Youth leaders at UN demand bold climate change action - Aljazeera link here
Swedish teenager Greta Thunberg opens the first ever Youth Summit on climate change at the UN headquarters.
"A day after climate strikes convulsed cities across the globe, with hundreds of thousands of young people opting to skip school and take to the streets instead, youth leaders have gathered at the United Nations to demand radical action on climate change. The UN invited 500 young activists and entrepreneurs to take part in Saturday's meeting - the first of its kind - at the body's headquarters in New York. It came days before a climate action summit scheduled to begin on Monday, which UN Secretary-General Antonio Guterres has called to seek greater commitments from world leaders on reducing their greenhouse gas emissions in line with the Paris accord to avert runaway global warming.
Among those in attendance on Saturday was 16-year-old Swedish activist Greta Thunberg, who started the climate strike movement with her lone protest in front of her country's parliament. "We showed we are united and young people are unstoppable," she said. Fellow activist Bruno Rodriguez, 19, who led school strikes in his native Argentina, warned that "climate and ecological crisis" was the "political, economic and cultural crisis of our time".
... The pair's comments came after masses of children skipped school on Friday to join global strikes that Thunberg said were "only the beginning" of the movement. Some four million people filled city streets around the world, organisers said, in what was billed as the biggest-ever protest against the threat posed to the planet by rising temperatures.
... Strike organisers 350.org said Friday's rallies were the start of 5,800 protests across 163 countries over the next week. The protests will coincide with a landmark UN report due to be unveiled next week which will warn global warming and pollution are ravaging Earth's oceans and icy regions in ways that could unleash misery on a global scale."

Global Climate Strike: Tens of thousands rally across the US - Aljazeera link here
At least 60,000 join teen activist Greta Thunberg's campaign in New York City, other US cities before UN summits
"New York City - Greta Thunberg arrived in the United States by sea three weeks ago after a rough journey across the Atlantic Ocean on a zero-emissions boat. Since then the Swedish teen activist has marched with the Fridays for Future demonstrators in New York City, testified before the US Congress and met former US President Barack Obama in Washington, DC.
On Friday, the fearless young Scandinavian warrior shepherded tens of thousands of students striking from school in New York with a loud refrain not just for their teachers, but for world leaders gathering at the UN Climate Action Summit next week.
"Fossil fuel CEOs will stop at nothing to squeeze every last drop of money from the earth," said Varshini Prakash, executive director of the Sunrise Movement, the US youth-led coalition calling for action on climate change. "[We] will strike again and again until we win."
Billed as the largest climate action in history, the New York marchers followed some 4,500 global rallies that began hours before in cities such as Kiribati, Sydney, New Delhi, Islamabad, Nairobi and London. Early unofficial estimates put the global total at more than three million participants."

'Americans are waking up': two thirds say climate crisis must be addressed - The Guardian link here
Major CBS News poll released as part of Covering Climate Now, a collaboration of more than 250 news outlets around the world to strengthen coverage of the climate story
"Two-thirds of Americans believe climate change is either a crisis or a serious problem, with a majority wanting immediate action to address global heating and its damaging consequences, major new polling has found. Amid a Democratic primary shaped by unprecedented alarm over the climate crisis and an insurgent youth climate movement that is sweeping the world, the polling shows substantial if uneven support for tackling the issue.
... “Americans are finally beginning waking up to the existential threat that the climate emergency poses to our society,” said Margaret Klein Salamon, a clinical psychologist and founder of the Climate Mobilization Project. “This is huge progress for our movement – and it’s young people that have been primarily responsible for that.” But while nearly all of those questioned accept that the climate is changing, there appears to be lingering confusion over why and scientists’ confidence over the causes.
There is a consensus among climate scientists that the world is heating up due to human activities such as burning fossil fuels for electricity generation and transportation, as well as cutting down forests. However, just 44% of poll respondents said human activity was a major contributor to climate change. More than a quarter said our impact was minor or nonexistent.
There is an even starker split on the findings of climate scientists. According to the CBS poll, 52% of Americans say “scientists agree that humans are a main cause” of the climate crisis, with 48% claiming there is disagreement among experts.
“This remains a vitally important misunderstanding – if you believe global warming is just a natural cycle, you’re unlikely to support policies intended to reduce carbon pollution, like regulations and taxes,” said Anthony Leiserowitz, director of the Yale Program on Climate Change Communication, which has made similar findings in its own, long-running polling.
“These results also again confirm a long-standing problem, which is that many Americans still believe scientists themselves are uncertain whether human-caused global warming is happening.
“Our own and others’ research has repeatedly found that this is a critical misunderstanding, promoted by the fossil fuel industry for decades, in order to sow doubt, increase public uncertainty and thus keep people stuck in the status quo, in a ‘wait and see’ mode.”
Similar to previous polls, the CBS research finds sharp ideological differences in attitudes to the climate crisis. While nearly seven in 10 Democratic voters understand that humans significantly influence the climate and 80% want immediate action, just 20% of Republicans think humans are a primary cause and barely a quarter want rapid action."

'Our land is no use any more': India's struggle to save its farms - Aljazeera link here
Land degradation and climate change are posing major threats to India's economy and farmers.
"... Land degradation is a phenomenon that Pappu, a labourer who brings his cattle to graze on what vegetation remains on the outskirts of Gurugram, knows all too well. He first came here several years ago from the neighbouring state of Rajasthan, forced to move when yields on his farm fell because of the rising salinity of the water supply. "Everything was fine and our yields were enough to sustain the family until this happened," Pappu, who's 50 and goes by one name, told Al Jazeera. He said most of the farmers in his village in Rajasthan gave up agriculture and migrated to Gurugram where they took up jobs as security guards, construction workers and day labourers.
... According to government data, nearly 30 percent of the land in India, or about 97 million hectares, is degraded. That's an area about the size of northern Europe. A major cause of land degradation is human activity. The World Health Organization cites "increasing and combined pressures of agricultural and livestock production (over-cultivation, overgrazing, forest conversion), urbanization [and] deforestation" as leading causes. Construction activity and the overuse of pesticides and chemical fertilisers for farming are also seen as contributors. Following famines in the late 1940s, fertilisers and pesticides helped India transform its agriculture sector by the early 1960s, a development that has come to be known as the Green Revolution. Ironically, the same chemicals have also had damaging effects on the soil. "We have reached a state where fertilisers have been used so much that it has led to a degradation of land quality," Saudamini Das, an economist at the Institute of Economic Growth in New Delhi, told Al Jazeera.
,,, The loss of land productivity can, in turn, contribute to climate change as the loss of plants makes it harder to draw excess carbon dioxide from the air. "Land degradation is a driver of climate change through emission of greenhouse gases and reduced rates of carbon uptake," the Intergovernmental Panel on Climate Change (IPCC) said in a report published last month.
,,, So what can governments and individuals do to restore their lands to health? Indian Prime Minister Narendra Modi said his government would commit to restoring 5 million hectares of degraded land by 2030, in addition to a previous commitment of 21 million hectares. But the UN says that won't be enough. It says India needs to restore at least 30 million hectares in the next decade to reverse land degradation by 2030."

World losing area of forest the size of the UK each year, report finds - The Guardian link here
Chance of ending deforestation by 2030 seems lower than when pledge was made five years ago
"An area of forest the size of the UK is being lost every year around the world, the vast majority of it tropical rainforest, with dire effects on the climate emergency and wildlife. The rate of loss has reached 26m hectares (64m acres) a year, a report has found, having grown rapidly in the past five years despite pledges made by governments in 2014 to reverse deforestation and restore trees.
,,, The New York declaration on forests was signed at the UN in 2014, requiring countries to halve deforestation by 2020 and restore 150m hectares of deforested or degraded forest land. But the rate of tree cover loss has gone up by 43% since the declaration was adopted, while the most valuable and irreplaceable tropical primary forests have been cut down at a rate of 4.3m hectares a year. The ultimate goal of the declaration, to halt deforestation by 2030 – potentially saving as much carbon as taking all the world’s cars off the roads – now looks further away than when the commitment was made.
... The report uses data up to 2018 in most cases, so the figures do not include the impact of the most recent burning in the Amazon. The report’s authors note that in June, deforestation rates in the Brazilian Amazon rose by 88% compared with the same month last year.
... Jo House, a reader in environmental science and policy at the University of Bristol, said: “Deforestation, mostly for agriculture, contributes around a third of anthropogenic CO2 emissions. At the same time, forests naturally take up around a third of anthropogenic CO2 emissions. “This natural sink provided by forests is at risk from the duel compounding threats of further deforestation and future climate change.
... One of the difficulties highlighted by the report is that of gaining private sector support and investment for keeping forests standing. While there are clear economic benefits to cutting down forests, in the form of timber production and expanded agriculture, there are few investments being made in keeping existing forests healthy. Another complicating factor is that many governments offer subsidies to agriculture, which provide perverse incentives for deforestation."

After bronze and iron, welcome to the plastic age, say scientists - The guardian link here
Plastic pollution has entered the fossil record, research shows
"Plastic pollution is being deposited into the fossil record, research has found, with contamination increasing exponentially since 1945. Scientists suggest the plastic layers could be used to mark the start of the Anthropocene, the proposed geological epoch in which human activities have come to dominate the planet. They say after the bronze and iron ages, the current period may become known as the plastic age.
The study, the first detailed analysis of the rise in plastic pollution in sediments, examined annual layers off the coast of California back to 1834. They discovered the plastic in the layers mirrors precisely the exponential rise in plastic production over the past 70 years. Most of the plastic particles were fibres from synthetic fabrics used in clothes, indicating that plastics are flowing freely into the ocean through waste water.
“Our love of plastic is being left behind in our fossil record,” said Jennifer Brandon, at the Scripps Institution of Oceanography at the University of California San Diego, who led the study. “It is bad for the animals that live at the bottom of the ocean: coral reefs, mussels, oysters and so on. But the fact that it is getting into our fossil record is more of an existential question.
... A study in 2016 showed a single clothes wash could release 700,000 microplastic fibres. “They are definitely not being disposed of properly,” Brandon said. “We are not filtering them out properly at household or waste treatment plant level. I think that is the next big frontier: what are we doing about our waste water and what we make our clothes out of, because clearly [the plastic] is washing straight into the ocean?”
Research is limited but eating plastic is known to harm marine creatures. Humans are believed to consume at least 50,000 microplastic particles a year through food and water. The health impact is unknown but microplastics can release toxic substances and may penetrate tissues."

UK facing EU outrage over ‘timebomb’ of North Sea oil rigs The Guardian link here
"Germany leads complaint against plan to leave polluted remains of Shell rigs in place
The British government is facing growing outrage from the European commission and five EU member states over its plans to leave some decommissioned oil rigs in the North Sea, with one senior German official describing the UK’s proposal as a “grotesque idea” that amounts to a “ticking timebomb”.
Several hundred oil drilling platforms in the North Sea are due to be decommissioned over the next three decades as they approach the end of their operational lifetime.
Disassembling the enormous pieces of infrastructure, each of which can be as tall as the Eiffel Tower, is a costly undertaking, and this year the UK government is intending to endorse plans by Shell to leave behind one steel jacket and the concrete bases beneath three of the platforms of its Brent oilfield installation.
The plans have raised alarm in Germany over the estimated 11,000 tonnes of raw oil and toxins remaining in the base of the three Brent installations, Bravo, Charlie and Delta, all erected in the East Shetland basin in the 1970s."

Hurricane Dorian: Catastrophic storm slams the Bahamas - Aljazeera link here
"Second-strongest Atlantic storm on record expected to continue to pound the Bahamas before moving northwest towards US.
In a slow, relentless advance, a catastrophic Hurricane Dorian kept pounding the northern Bahamas early on Monday, as one of the strongest Atlantic storms ever recorded left wrecked homes, shredded roofs, tumbled cars and toppled power poles in its wake.
The storm was stalled over Grand Bahama Island, packing maximum sustained winds of 249 kilometres per hour (155 mph) and moving at 2 km/h, the Miami-based National Hurricane Center (NHC) said in an advisory at 11am (16:00 GMT). Dorian was expected to pound Grand Bahama for much of the day.
... On Sunday, Dorian's maximum sustained winds reached 297 km/h (185 mph), with gusts up to 354 km/h (220 mph), tying the record for the most powerful Atlantic hurricane to ever make landfall. That equalled the Labor Day hurricane of 1935, before storms were named. The only recorded storm that was more powerful was Hurricane Allen in 1980, with 305 km/h (190 mph) winds, though it did not make landfall at that strength.
... South Carolina Governor Henry McMaster issued an order on Sunday for the mandatory evacuation of his state's entire coast. The order, which covers about 830,000 people, was to take effect at noon on Monday, at which point state troopers were to make all lanes on major coastal highways one-way heading inland."

Great Barrier Reef outlook now 'very poor', Australian government review says - The Guardian link here
Five-yearly report says climate change is escalating the threat and window of opportunity for action is now.
"The outlook for the Great Barrier Reef has deteriorated from poor to very poor according to an exhaustive government report that warns the window of opportunity to improve the natural wonder’s future “is now”.
The Great Barrier Reef Marine Park Authority’s outlook report, published every five years, finds coral reefs have declined to a very poor condition and there is widespread habitat loss and degradation affecting fish, turtles and seabirds.
It warns the plight of the reef will not improve unless there is urgent national and global action to address the climate crisis, which it described as its greatest threat."

The Amazon Is Burning at a Record Rate, And The Devastation Can Be Seen From Space - Science Alert website link here
"The "lungs of the planet" are burning. As thousands of fiery infernos rage across the Amazon rainforest, tropical vegetation, trees, and the fauna they house are being razed. Since August 15, more than 9,500 new forest fires have started across Brazil, primarily in the Amazon basin.
This year so far, scientists have recorded more than 74,000 fires in Brazil. That's nearly double 2018's total of about 40,000 fires. The surge marks an 83 percent increase in wildfires over the same period of 2018, Brazil's National Institute for Space Research reported. The largest state in Brazil, Amazonas, declared a state of emergency on Monday.Already, 2019 has the highest number of fires observed in a single year since researchers began keeping track in 2013 – and there are still four months to go.
As the world's largest rainforest, the Amazon plays a crucial role in keeping our planet's carbon-dioxide levels in check. Plants and trees take in carbon dioxide and release oxygen back into the air in their process of photosynthesis. This is why the Amazon, which covers 2.1 million square miles, is often referred to as the "lungs of the planet": The forest produces 20 percent of the oxygen in our planet's atmosphere.
Typically, the Amazonian dry season runs from July to October, peaking in late September. Wetter weather during the rest of the year minimizes the risk of fires at other times. But during the dry season, blazes can spark from natural sources, like lightning strikes. Farmers and loggers also purposefully set fire to the rainforest to clear swaths of the Amazon for industrial or agricultural use.
The fires raging in the Amazon now have widespread effects on the rest of Brazil. The smoke plumes from the blazes spread from the state of Amazonas to the nearby states of Pará and Mato Grosso, and even blotted out the sun in São Paulo – a city more than 2,000 miles (3,200 kilometers) away. On Monday, people in São Paulo reported on social media that the sky had gone dark between 3 and 4 pm local time."

Microplastics ‘significantly contaminating the air’, scientists warn - The Guardian link here
"Discovery of pollution in snowfall from the Arctic to the Alps leads to call for urgent research on potential human health impacts
Abundant levels of microplastic pollution have been found in snow from the Arctic to the Alps, according to a study that has prompted scientists to warn of significant contamination of the atmosphere and demand urgent research into the potential health impacts on people.
Snow captures particles from the air as it falls and samples from ice floes on the ocean between Greenland and Svalbard contained an average of 1,760 microplastic particles per litre, the research found. Even more – 24,600 per litre on average – were found at European locations. The work shows transport by winds is a key factor in microplastics contamination across the globe.
The scientists called for research on the effect of airborne microplastics on human health, pointing to an earlier study that found the particles in cancerous human lung tissue. In June, another study showed people eat at least 50,000 microplastic particles per year.
Many millions of tonnes of plastic are discarded into the environment every year and are broken down into small particles and fibres that do not biodegrade. These particles, known as microplastics, have now been found everywhere from high mountains to deep oceans and can carry toxic chemicals and harmful microbes. ..."

Arctic wildfires spew soot and smoke cloud bigger than EU. Plume from unprecedented blazes forecast to reach Alaska as fires rage for third month. - The Guardian link here
"A cloud of smoke and soot bigger than the European Union is billowing across Siberia as wildfires in the Arctic Circle rage into an unprecedented third month.The normally frozen region, which is a crucial part of the planet’s cooling system, is spewing carbon dioxide into the atmosphere and worsening the manmade climate disruption that created the tinderbox conditions.
A spate of huge fires in northern Russia, Alaska, Greenland and Canada discharged 50 megatonnes of CO2 in June and 79 megatonnes in July, far exceeding the previous record for the Arctic. The intensity of the blazes continues with 25 megatonnes in the first 11 days of August – extending the duration beyond even the most persistent fires in the 17-year dataset of Europe’s satellite monitoring system.
Mark Parrington, a scientist in the Copernicus Atmosphere Monitoring Service, said the previous record was just a few weeks. “We haven’t seen this before,” he said. “The fire intensity is still well above average.” He said the affected regions previously registered unusually high temperatures and a low level of soil moisture, which created the perfect conditions for ignition. Globally, June and July were the hottest months ever measured."

Toxic fish: Is climate change making cod & tuna dangerous to eat? - Aljazeera link here
"Harvard scientists say climate change is making fish toxic, and warn that eating tainted fish can cause brain damage. Climate change and overfishing are increasing levels of toxic mercury in cod and tuna - and this can cause neurological disorders in children and babies whose mothers eat fish while pregnant, a study by Harvard scientists said on Wednesday.
The concentration of methylmercury - an organic compound which can cause severe damage to the brain and nervous system - rose by 23 percent in cod and by 27 percent in bluefin tuna in the Atlantic Ocean's Gulf of Maine over about three decades, the study said. "Methylmercury is ... particularly harmful during the third trimester of pregnancy when the brain is developing most rapidly and for young children," said Elsie Sunderland, co-author of the paper, which was published in the journal Nature
... "It's not that everyone should be terrified after reading our paper and stop eating seafood, which is very healthy, nutritious food," said Sunderland, a professor of environmental chemistry at Harvard University's School of Public Health. "We wanted to show people that [climate change] can have a direct impact on what you're eating today, that these things can affect your health ... not just things like severe weather and flooding and sea-level rise."
... A 2018 Harvard study found coal-fired power plants are the top source of mercury emissions in the US, as burning coal releases pollution into the air, which then falls into soil and water where it is eaten by aquatic organisms and fish. "We need to reduce human emissions (of mercury) and the largest source in the United States presently, accounting for about 40 percent of emissions, is coal-fired utilities," Sunderland told the Thomson Reuters Foundation."

We must change food production to save the world, says leaked report - The Guardian link here
"Attempts to solve the climate crisis by cutting carbon emissions from only cars, factories and power plants are doomed to failure, scientists will warn this week.
A leaked draft of a report on climate change and land use, which is now being debated in Geneva by the Intergovernmental Panel on Climate Change (IPCC), states that it will be impossible to keep global temperatures at safe levels unless there is also a transformation in the way the world produces food and manages land.
Humans now exploit 72% of the planet’s ice-free surface to feed, clothe and support Earth’s growing population, the report warns. At the same time, agriculture, forestry and other land use produces almost a quarter of greenhouse gas emissions.
In addition, about half of all emissions of methane, one of the most potent greenhouse gases, come from cattle and rice fields, while deforestation and the removal of peat lands cause further significant levels of carbon emissions. The impact of intensive agriculture – which has helped the world’s population soar from 1.9 billion a century ago to 7.7 billion – has also increased soil erosion and reduced amounts of organic material in the ground.
... The new IPCC report emphasises that land will have to be managed more sustainably so that it releases much less carbon than at present. Peat lands will need to be restored by halting drainage schemes; meat consumption will have to be cut to reduce methane production; while food waste will have to be reduced."

'People are dying': how the climate crisis has sparked an exodus to the US - The Guardian link here
"As part of the Running Dry series, the Guardian looks at how drought and famine are forcing Guatemalan families to choose between starvation and migration.
... amid a deepening global climate crisis, drought, famine and the battle for dwindling natural resources are increasingly being recognized as major factors in the exodus.
... “Over the past six years, the lack of rainfall has been our biggest problem, causing crops to fail and widespread famine,” said the climate scientist Edwin Castellanos, the dean of the research institute at Guatemala’s Universidad del Valle.
... As a result, entire families have been migrating in record numbers: since October 2018, more than 167,000 Guatemalans travelling in family groups have been apprehended at the US border, compared with 23,000 in 2016.
Those who remain, often depend on money sent home by emigres, especially in rural areas, which received more than half the $9.2bn of remittances sent to Guatemala in 2018.
... Local political factors are also important. Water shortages and poverty are causally linked to the country’s skewed land distribution: roughly 2% of the population control 70% of all productive farmland. In Chiquimula, 71% of people live in poverty, and 40% in extreme poverty.
... Guatemala has the sixth-highest malnutrition rate in the world with at least 47% of children suffering chronic malnourishment. Malnutrition rates are even higher among the country’s 24 indigenous communities, rising to over 60% in Camotán.
... “This isn’t poverty – or even extreme poverty: this is a famine, and people are dying,” said Rodimiro Lantán from Comundich, a grassroots Ch’orti’ organisation helping communities reforest ancestral lands in an effort to prevent forced migration.
Families face an impossible choice: stay and risk starvation, or gamble everything on the perilous migrant trail. “They risk their lives if they stay – and if they go,” said Lantán.
One local who took that chance was Juan de Léon Gutiérrez, a 16-year old boy from a nearby village. In April, he died at a Texas children’s hospital just days after he was taken into US immigration custody – one of at least eight Guatemalan children to have died shortly after crossing the US border since May 2018."

Today is Overshoot Day: Earth Overshoot Day website link here
“Earth Overshoot Day marks the date when humanity’s demand for ecological resources and services in a given year exceeds what Earth can regenerate in that year. We maintain this deficit by liquidating stocks of ecological resources and accumulating waste, primarily carbon dioxide in the atmosphere. Earth Overshoot Day is hosted and calculated by Global Footprint Network, an international think tank that coordinates research, develops methodological standards and provides decision-makers with a menu of tools to help the human economy operate within Earth’s ecological limits.
To determine the date of Earth Overshoot Day for each year, Global Footprint Network calculates the number of days of that year that Earth’s biocapacity suffices to provide for humanity’s Ecological Footprint. The remainder of the year corresponds to global overshoot. Earth Overshoot Day is computed by dividing the planet’s biocapacity (the amount of ecological resources Earth is able to generate that year), by humanity’s Ecological Footprint (humanity’s demand for that year), and multiplying by 365, the number of days in a year:”

Arctic wildfires: What's caused huge swathes of flames to spread? - BBC News link here
"Wildfires are ravaging the Arctic, with areas of northern Siberia, northern Scandinavia, Alaska and Greenland engulfed in flames.
Lightning frequently triggers fires in the region but this year they have been worsened by summer temperatures that are higher than average because of climate change. Plumes of smoke from the fires can be seen from space.
Mark Parrington, a wildfires expert at the Copernicus Atmosphere Monitoring Service (Cams), described them as "unprecedented". How bad is it? There are hundreds of fires covering mostly uninhabited regions across eastern Russia, northern Scandinavia, Greenland and Alaska.
But smoke is affecting wider surrounding areas, engulfing some places completely. Cities in eastern Russia have noted a significant decrease in air quality since the fires started. The smoke has reportedly reached Russia's Tyumen region in western Siberia, six time zones away from the fires on the east coast.
In June, the fires released an estimated 50 megatonnes of carbon dioxide - the equivalent of Sweden's annual carbon output, according to Cams. How unuasual is this? Arctic fires are common between May and October and wildfires are a natural part of an ecosystem, offering some benefits for the environment, according to the Alaska Centers website. But the intensity of these fires, as well as the large area they have taken up, make these unusual. It is unusual to see fires of this scale and duration at such high latitudes in June," said Mr Parrington.
"But temperatures in the Arctic have been increasing at a much faster rate than the global average, and warmer conditions encourage fires to grow and persist once they have been ignited." Extremely dry ground and hotter than average temperatures, combined with heat lightning and strong winds, have caused the fires to spread aggressively. The burning has been sustained by the forest ground, which consists of exposed, thawed, dried peat - a substance with high carbon content.
Global satellites are now tracking a swathe of new and ongoing wildfires within the Arctic Circle. The conditions were laid in June, the hottest June for the planet yet observed in the instrumented era. The fires are releasing copious volumes of previously stored carbon dioxide and methane - carbon stocks that have in some cases been held in the ground for thousands of years.
Scientists say what we're seeing is evidence of the kind of feedbacks we should expect in a warmer world, where increased concentrations of greenhouse gases drive more warming, which then begets the conditions that release yet more carbon into the atmosphere. A lot of the particulate matter from these fires will eventually come to settle on ice surfaces further north, darkening them and thus accelerating melting. It's all part of a process of amplification."

Europe heatwave could 'enhance melting of Greenland ice sheet' - Aljazeera link here
"Ice has been melting at high levels over the last few weeks in Greenland, World Meteorological Organization says.
The United Nations weather agency has voiced "concern" that hot air producing a record-breaking heatwave across much of Western Europe is headed towards Greenland and that it could lead to a faster ice melt.
Heat records in France, Belgium, the Netherlands and Germany tumbled in recent days as hot air surged northwards from North Africa and Spain, sending the mercury soaring upwards of 40C.
World Meteorological Organization (WMO) spokesperson Clare Nullis said in the Swiss city of Geneva on Friday that forecasts suggest the air is heading towards Greenland.
This would result in "high temperatures and consequently enhanced melting of the Greenland ice sheet", Nullis said.
Ice has been melting at high levels over the last few weeks in Greenland, according to WMO.
Nullis cited data from Denmark's Polar Portal, which measures the daily gains and losses in surface mass of the Greenland ice sheet.
"In July alone, it lost 160 billion tonnes of ice through surface melting. That's roughly the equivalent of 64 million Olympic-sized swimming pools. Just in July. Just surface melt - it's not including ocean melt as well," Nullis said.
The Greenland Ice Sheet covers 80 percent of the island and has developed over many thousands of years, with layers of snow compressed into ice.
The dome of ice rises to a height of 3,000 metres and the total volume of the ice sheet is approximately 2.9 million cubic kilometres, which would raise global sea levels by seven metres if it melted entirely, according to the Polar Portal website.

Climate fears as the UK has second hottest day on record - The Guardian link here
"Cambridge was hottest spot at 38.1C, as Met Office issues storm and flood warnings overnight
Britain has experienced its hottest July day and second hottest day on record as the mercury hit 38.1C, the Met Office said.
The highest temperature recorded on Thursday was in Cambridge, which is only the second time temperatures over 100F have been recorded in the UK, according to the Met Office. Thursday’s record temperature surpassed the previous high for the month of 36.7C (98.06F) set at Heathrow in July 2015.
Sweltering temperatures could spark thundery downpours, with a yellow warning for thunderstorms issued for most of England except the south-west, and parts of Scotland, until 4am on Friday. The storms could lead to flash flooding, disruption of train and bus services and even power cuts.
Experts at the Met Office say the current weather pattern is driving hot air from the south, but there is “no doubt” the climate crisis is playing a role in driving what could be unprecedented temperature highs."

Climate change: Current warming 'unparalleled' in 2,000 years - BBC News link here
"The speed and extent of current global warming exceeds any similar event in the past 2,000 years, researchers say. ... The scientists say it shows many of the arguments used by climate sceptics are no longer valid.
When scientists have surveyed the climactic history of our world over the past centuries a number of key eras have stood out. These ranged from the "Roman Warm Period", which ran from AD 250 to AD 400, and saw unusually warm weather across Europe, to the famed Little Ice Age, which saw temperatures drop for centuries from the 1300s.
The events were seen by some as evidence that the world has warmed and cooled many times over the centuries and that the warming seen in the world since the industrial revolution was part of that pattern and therefore nothing to be alarmed about. Three new research papers show that argument is on shaky ground.
The science teams reconstructed the climate conditions that existed over the past 2,000 years using 700 proxy records of temperature changes, including tree rings, corals and lake sediments. They determined that none of these climate events occurred on a global scale. The researchers say that, for example, the Little Ice Age was at its strongest in the Pacific Ocean in the 15th Century, while in Europe it was the 17th Century. Generally, any longer-term peaks or troughs in temperature could be detected in no more than half the globe at any one time, The "Medieval Warm Period", which ran between AD 950 and AD 1250 only saw significant temperature rises across 40% of the Earth's surface.
Today's warming, by contrast, impacts the vast majority of the world. "We find that the warmest period of the past two millennia occurred during the 20th Century for more than 98% of the globe," one of the papers states. "This provides strong evidence that anthropogenic (human induced) global warming is not only unparalleled in terms of absolute temperatures but also unprecedented in spatial consistency within the context of the past 2,000 years."
What the researchers saw is that prior to the modern industrial era, the most significant influence on climate was volcanoes. They found no indication that variations in the Sun's radiation impacted mean global temperatures.
The current period, say the authors, significantly exceeds natural variability. "We see from the instrumental data and also from our reconstruction that in the recent past the warming rate clearly exceeds the natural warming rates that we calculated - that's another view to look at the extraordinary nature of the present warming," said Dr Raphael Neukom, from the University of Bern, Switzerland.
While the researchers did not set out to test whether humans were the chief influence on the current climate, their findings indicate clearly that this is the case. "We do not focus on looking at what's causing the most recent warming as this has been done many times and the evidence is always agreeing that it is the anthropogenic cause," said Dr Neukom. "We do not explicitly test this; we can only show that natural causes are not sufficient from our data to actually cause the spatial pattern and the warming rate that we are observing now."
Other scientists have been impressed with the quality of the new studies. "They have done this across the globe with more than 700 records over the past 2,000 years; they have corals and lakes and also instrumental data," said Prof Daniela Schmidt from the University of Bristol, UK, who was not involved with the studies. "And they have been very careful in assessing the data and the inherent bias that any data has, so the quality of this data and the coverage of this data is the real major advance here; it is amazing."
Many experts say that this new work debunks many of the claims made by climate sceptics in recent decades. "This paper should finally stop climate change deniers claiming that the recent observed coherent global warming is part of a natural climate cycle," said Prof Mark Maslin, from University College London, UK, who wasn't part of the studies. "This paper shows the truly stark difference between regional and localised changes in climate of the past and the truly global effect of anthropogenic greenhouse emissions."
The three papers have been published in the journals Nature (1) and Nature Geoscience (2), (3)."

World hunger on the rise as 820m at risk, UN report finds - The Guardian link here
Eliminating hunger by 2030 is an immense challenge, say heads of UN agencies
More than 820 million people worldwide are still going hungry, according to a UN report that says reaching the target of zero hunger by 2030 is “an immense challenge”.
The number of people with not enough to eat has risen for the third year in a row as the population increases, after a decade when real progress was made. The underlying trend is stabilisation, when global agencies had hoped it would fall.
Millions of children are not getting the nutrition they need. The UN says the pace of progress in halving child stunting and reducing the number of low birthweight babies is too slow, which jeopardises the chances of achieving another of the sustainable development goals.
Nearly half of all child deaths in Africa stem from hunger, study shows
The report is from the UN Food and Agriculture Organization, the International Fund for Agricultural Development, the UN Children’s Fund (Unicef), the World Food Programme and the World Health Organization.
While hunger remains widespread, obesity – also related to malnutrition – continues to rise in all regions. There are 338 million school-age children and adolescents who are overweight and 672 million obese adults. Asia and Africa, which have nine out of 10 of all stunted children and more than nine out of 10 of all wasted children worldwide, are also home to nearly three-quarters of all overweight children worldwide, largely driven by unhealthy diets.
One in seven babies around the world were born with low birthweight in 2015, the report says, many of them to adolescent mothers. That puts them at risk of poor development.
The world’s population has steadily grown, with most people living in urban areas. Technology has “evolved at a dizzying pace, while the economy has become increasingly interconnected and globalised”, say the heads of the UN agencies in a foreword to the report.
“Many countries, however, have not witnessed sustained growth as part of this new economy. The world economy as a whole is not growing as much as expected.”
Climate breakdown is affecting agriculture and the number of farmers has declined. “All of this has led to major shifts in the way in which food is produced, distributed and consumed worldwide – and to new food security, nutrition and health challenges.”
Hunger is increasing in countries where economic growth is lagging and there is income inequality.
“Our actions to tackle these troubling trends will have to be bolder,” the UN leaders say. “We must foster pro-poor and inclusive structural transformation focusing on people and placing communities at the centre to reduce economic vulnerabilities and set ourselves on track to ending hunger, food insecurity and all forms of malnutrition.”

Indian water train arrives with desperately needed relief for Chennai - CNN link here
"A train carrying millions of liters of water rolled into the southern Indian city of Chennai for the first time on Friday, providing desperately needed relief to residents who have been facing an acute water shortage for the past month.
The city, Tamil Nadu's state capital and one of India's biggest metropolitan areas, has been crippled by the shortage brought on by poor water management, last year's disappointing monsoon and continuous population growth.
... Harmandar Singh, a senior official for state services, officially greeted the service. He said there had been no significant rains for 180 to 190 days, and that last year's failed monsoon had contributed to the problem.
... For the past several months, city residents have been forced to rely on government and privately run water tankers that sweep through the streets throughout the day.
The new train service -- a regular supply that aims to bring in 10 million liters of water daily from a dam located about 360 kilometers (224 miles) away in Jolarpettai -- is expected to reduce the pressure on the strained city resources.
The arrangement "is likely to continue till the water situation improves in Chennai area," Indian Railways said in a statement.
Chennai's water problem is the latest reminder of India's impending water crisis.
Unpredictable weather patterns, brought on by climate change, coupled with shrinking groundwater levels caused by years of unregulated use have resulted in widespread droughts across the country.
Chennai is the first of India's major cities to try to combat this problem.
... Millions of city residents line up every morning in their neighborhoods to fill smalls pots of water from the water tankers provided by the state. Some get a daily ration, while others, such as residents from low-income neighborhoods, wait longer for their share due to an unsteady supply.
... Around 600 million of India's 1.3 billion people are currently facing an acute water shortage, according to a 2018 report released by Niti Aayog, a government-run think tank.
"This crisis is further driven by a poorly defined legal framework for groundwater that rests ownership with landowners and leads to unchecked extraction. This crisis is most acute in the Indian agriculture sector, where groundwater accounts for 63% of all irrigation water," the report said."

Fossil fuels increasingly offer a poor return on energy investment - Tech Explore website link here
"... Previously, the estimated ratios for energy return on investment (EROI) have favoured fossil fuels over renewable energy sources. Oil, coal and gas are typically calculated to have ratios above 25:1, this means roughly one barrel of oil used yields 25 barrels to put back into the energy economy. Renewable energy sources often have much lower estimated ratios, below 10:1.
However, these fossil fuel ratios are measured at the extraction stage, when oil, coal or gas is removed from the ground. These ratios do not take into account the energy required to transform oil, coal and gas into finished fuels such as petrol used in cars, or electricity used by households.
A new study, co-authored by scientists from the Sustainability Research Institute at the University of Leeds, has calculated the EROI for fossil fuels over a 16 year period and found that at the finished fuel stage, the ratios are much closer to those of renewable energy sources—roughly 6:1, and potentially as low as 3:1 in the case of electricity.
The study, undertaken as part of the UK Energy Research Centre programme and published today in Nature Energy, warns that the increasing energy costs of extracting fossil fuels will cause the ratios to continue to decline, pushing energy resources towards a "net energy cliff". This is when net energy available to society declines rapidly due to the increasing amounts of "parasitical" energy required in the energy production.
The researchers emphasise that these findings make a strong case for rapidly stepping up investment in renewable energy sources and that the renewables transition may actually halt—or reverse—the decline in global EROI at the finished fuel stage.
Study co-author Dr. Paul Brockway, an expert in energy-economy modelling at the School of Earth and Environment at Leeds, said: "Measuring energy return on investment of fossil fuels at the extraction stage gives the misleading impression that we have plenty of time for a renewable energy transition before energy constraints are a concern.
"Those measurements are essentially predicating the potential energy output of newly-extracted sources like crude oil. But crude oil isn't used to heat our homes or power our cars. It makes more sense for calculations to consider where energy enters the economy, and that puts us much closer to the precipice.
"The ratios will only continue to decline because we are swiftly reaching the point where all the easilyaccessible fossil fuel sources are becoming exhausted. By stepping up investment in renewable energy sources we can help ensure that we don't tip over the edge."
Study co-author Dr. Lina Brand-Correa, an expert in the social aspects of energy use on the Living Well within Limits (LiLi) project at Leeds said: "There is too much focus on the initial economic costs of transitioning to renewable energy.
"Renewable infrastructure, such as wind farms and solar panels, do require a large initial investment, which is one of the reasons why their energy return on investment ratios have been so low until now.
"But the average energy return on investment for all fossil fuels at the finished fuel stage declined by roughly 23 per cent in the 16 year period we considered. This decline will lead to constraints on the energy available to society in the not-so-distant future, and these constraints might unfold in rapid and unexpected ways.
"Once the renewable infrastructure is built and dependency on fossil fuel decreases, the energy return- on-investment for renewable sources should go up. This must be considered for future policy and energy infrastructure investments decisions, not only to meet climate change mitigation commitments but to ensure society continues to have access to the energy it needs."

One climate crisis disaster happening every week, UN warns - The Guardian link here
Developing countries must prepare now for profound impact, disaster representative says
"Climate crisis disasters are happening at the rate of one a week, though most draw little international attention and work is urgently needed to prepare developing countries for the profound impacts, the UN has warned.
Catastrophes such as cyclones Idai and Kenneth in Mozambique and the drought afflicting India make headlines around the world. But large numbers of “lower impact events” that are causing death, displacement and suffering are occurring much faster than predicted, said Mami Mizutori, the UN secretary-general’s special representative on disaster risk reduction. “This is not about the future, this is about today.”
This means that adapting to the climate crisis could no longer be seen as a long-term problem, but one that needed investment now, she said. “People need to talk more about adaptation and resilience.”
Estimates put the cost of climate-related disasters at $520bn a year, while the additional cost of building infrastructure that is resistant to the effects of global heating is only about 3%, or $2.7tn in total over the next 20 years."

Japan orders over a million to evacuate amid torrential rains - Aljazeera link here
"A total of 1.1 million people in Kagoshima and Miyazaki prefectures have been ordered to shelters, authorities say.
Authorities in Japan have issued evacuation orders for more than one million people in southern parts of the country hit by heavy rains, a year after deadly floods killed more than 200 people.
Small landslides were already being reported in parts of the affected area, public broadcaster NHK reported.
It said a total of 1.1 million people in Kagoshima and Miyazaki prefectures on the island of Kyushu had been ordered to shelters.
Landslides swept away several cars and buried a house in Kagoshima, the broadcaster said.
At least four people have been hurt, NHK reported later on its Twitter account, citing police and firefighters. In one case a car flipped onto its side in a mudslide, injuring a woman and her child, NHK said.
There were no official details on how many people had heeded the warnings to leave their homes.
At an evacuation centre in Kagoshima, elderly residents sat on the floor eating with their bedding and other belongings spread out around them.
The evacuation order is issued when a natural disaster is highly likely to occur and municipalities repeatedly urge residents to leave their homes, although the instruction is frequently ignored.
It is the most serious warning issued before a disaster actually occurs. The scale's highest level is activated once a disaster is declared and orders people to take measures to protect their lives.
About 868,000 people in Kagoshima, Kumamoto and Miyazaki prefectures are under a lower-level warning advising them to evacuate, according to NHK."

June was hottest ever recorded on Earth, European satellite agency announces - Independent link here
"Experts say climate change contributed to record-breaking temperatures across Europe
Last month was the hottest June ever recorded, the EU‘s satellite agency has announced.
Data provided by the Copernicus Climate Change Service (C3S), implemented by the European Centre for Medium-Range Weather Forecasts on behalf of the EU, showed that the global average temperature for June 2019 was the highest on record for the month.
The data showed European average temperatures were more than 2C above normal and temperatures were 6-10C above normal over most of France, Germany and northern Spain during the final days of the month, according to C3S.
The global average temperature was about 0.1C higher than during the previous warmest June in 2016.
Experts have said climate change made last week’s record-breaking European heatwave at least five times as likely to happen, according to recent analysis.
Rapid assessment of average temperatures in France between 26-28 June showed a “substantial” increase in the likelihood of the heatwave happening as a result of human-caused global warming, experts at the World Weather
Attribution group said.
The recent heatwave saw France record the hottest temperature in the country’s history (45.9C) and major wildfires across Spain, where temperatures exceeded 40C.
Germany, Poland and Czech Republic also recorded their highest temperatures for June last week."

India reels under worst drought in decades, heat kills dozens - Aljazeera link here
"Western state of Maharashtra witnesses worst drought in 47 years, while intense heat kills dozens in impoverished Bihar.
Almost half of India - an area home to more than 500 million people - is facing drought-like conditions while a blistering heatwave has killed dozens of people in the impoverished eastern state of Bihar.
As the country suffers its lowest rainfall ahead of a monsoon season in more than six decades, the western state of Maharashtra witnesses its worst drought in 47 years, forcing many to leave their lands and take shelter in relief camps, as they wait for monsoon rains.
India's hot season has been particularly harsh this year, with temperatures rising above 50 degrees Celsius in the western state of Rajasthan.
In Bihar, severe heat during the weekend killed at least 76 people, according to the dpa news agency.
Most deaths occurred in three districts of Bihar - Aurangabad, Gaya and Nawada - where temperatures hovered around 45 degrees Celsius as India entered the third week of searing heat.
On Sunday, Bihar Chief Minister Nitish Kumar announced a compensation of 400,000 rupees ($5,700) for the family of each heatwave victim, while federal Health Minister Harsh Vardhan asked people to not leave their homes until temperatures fell.
"Intense heat affects brain and leads to various health issues," he said.
A heatwave in 2015 left more than 3,500 dead in India and Pakistan."

Millions across South America hit by massive power cut - The Guardian link here
"Failure leaves people in Argentina and Uruguay without electricity
Tens of millions of people across South America were without electricity early on Sunday after a massive power failure left Argentina and Uruguay almost completely in the dark.
The Argentine newspaper Clarín said the “gigantic” power collapse – which it called the worst in Argentina’s recent history – had struck at just after 7am local time, affecting virtually the entire country as well as Uruguay, Paraguay and some cities in Chile.
“This is an unprecedented situation that will be thoroughly investigated,” the Argentine president, Mauricio Macri, vowed as authorities fought to restore electricity supply to the country’s 44 million residents.
Argentina’s energy secretariat blamed the blackout on a failure in the transmission of electricity from the Yacyretá hydroelectric dam on the Paraná River and said it was working towards a “complete restoration” of power. The reason for the breakdown was not immediately clear.
By Sunday afternoon Macri claimed electricity had been restored to about half of the country’s users. However, authorities admitted they still could not explain what had gone wrong.
The energy secretary, Gustavo Lopetegui, described the “very serious” outage as “extraordinary” but admitted it could take up to a fortnight to understand exactly why the country had suffered a “complete disconnection” and who might be to blame.
...Clarín said Sunday’s outage paralysed part of the transport system in Argentina’s capital, Buenos Aires, stopping trains from circulating and knocking out traffic lights. Video footage showed heavy rain beating down on the city’s eerily quiet streets.
...Buenos Aires water company AySA asked residents to conserve water because the outage meant its distribution system was not functioning.
...The incident comes just over three months after a series of historic blackouts began to blight crisis-stricken Venezuela, plunging millions of its citizens into the darkness for days at a time.
Venezuela’s president, Nicolás Maduro, blamed those failures on US-backed saboteurs he claimed were waging “an electrical war” against his administration. But Maduro’s opponents and most specialists said corruption and poor maintenance of Venezuela’s electrical grid were the true explanations.
Millions of Brazilians were affected by a massive blackout in 2009 that authorities said was caused by a failure in the transmission of electricity from the Itaipu hydroelectric dam."

The climate crisis is our third world war. It needs a bold response. Joseph Stiglitz - The Guardian link here
"Critics of the Green New Deal ask if we can afford it. But we can’t afford not to: our civilisation is at stake.
Advocates of the Green New Deal say there is great urgency in dealing with the climate crisis and highlight the scale and scope of what is required to combat it. They are right. They use the term “New Deal” to evoke the massive response by Franklin Delano Roosevelt and the United States government to the Great Depression. An even better analogy would be the country’s mobilization to fight World War II.
Critics ask, “Can we afford it?” and complain that Green New Deal proponents confound the fight to preserve the planet, to which all right-minded individuals should agree, with a more controversial agenda for societal transformation. On both accounts the critics are wrong.
Yes, we can afford it, with the right fiscal policies and collective will. But more importantly, we must afford it. The climate emergency is our third world war. Our lives and civilization as we know it are at stake, just as they were in the second world war."

The world needs topsoil to grow 95% of its food – but it's rapidly disappearing - The Guardian link here
Without efforts to rebuild soil health, we could lose our ability to grow enough nutritious food to feed the planet’s population.
The world grows 95% of its food in the uppermost layer of soil, making topsoil one of the most important components of our food system. But thanks to conventional farming practices, nearly half of the most productive soil has disappeared in the world in the last 150 years, threatening crop yields and contributing to nutrient pollution, dead zones and erosion. In the US alone, soil on cropland is eroding 10 times faster than it can be replenished.
If we continue to degrade the soil at the rate we are now, the world could run out of topsoil in about 60 years, according to Maria-Helena Semedo of the UN’s Food and Agriculture Organization. Without topsoil, the earth’s ability to filter water, absorb carbon, and feed people plunges. Not only that, but the food we do grow will probably be lower in vital nutrients.
The modern combination of intensive tilling, lack of cover crops, synthetic fertilizers and pesticide use has left farmland stripped of the nutrients, minerals and microbes that support healthy plant life. But some farmers are attempting to buck the trend and save their lands along with their livelihoods.

Why the Guardian is changing the language it uses about the environment - The Guardian link here
"From now, house style guide recommends terms such as ‘climate crisis’ and ‘global heating’
The Guardian has updated its style guide to introduce terms that more accurately describe the environmental crises facing the world.
Instead of “climate change” the preferred terms are “climate emergency, crisis or breakdown” and “global heating” is favoured over “global warming”, although the original terms are not banned.
“We want to ensure that we are being scientifically precise, while also communicating clearly with readers on this very important issue,” said the editor-in-chief, Katharine Viner. “The phrase ‘climate change’, for example, sounds rather passive and gentle when what scientists are talking about is a catastrophe for humanity.”
“Increasingly, climate scientists and organisations from the UN to the Met Office are changing their terminology, and using stronger language to describe the situation we’re in,” she said.
The United Nations secretary general, António Guterres, talked of the “climate crisis” in September, adding: “We face a direct existential threat.” The climate scientist Prof Hans Joachim Schellnhuber, a former adviser to Angela Merkel, the EU and the pope, also uses “climate crisis”.
In December, Prof Richard Betts, who leads the Met Office’s climate research, said “global heating” was a more accurate term than “global warming” to describe the changes taking place to the world’s climate. In the political world, UK MPs recently endorsed the Labour party’s declaration of a “climate emergency”.
The scale of the climate and wildlife crises has been laid bare by two landmark reports from the world’s scientists. In October, they said carbon emissions must halve by 2030 to avoid even greater risks of drought, floods, extreme heat and poverty for hundreds of millions of people. In May, global scientists said human society was in jeopardy from the accelerating annihilation of wildlife and destruction of the ecosystems that support all life on Earth."

Australia faces 'world-first' climate change human rights case - Aljazeera link here
"Torres Strait Islanders say Australia's failure to tackle climate change puts their homeland and culture in danger.
Indigenous people from the low-lying Torres Strait Islands off Australia's northeast coast will file a landmark complaint with the United Nations on Monday, accusing the government of breaching their human rights by failing to tackle climate change.
The eight Torres Strait Islanders will tell the UN Human Rights Committee in the Swiss city of Geneva that rising seas caused by global warming are threatening their homelands and culture, according to lawyers representing the group.
ClientEarth, an environmental law non-profit organisation that is backing the case, said it was the first to be lodged with the UN linking alleged government inaction on climate change to the violation of human rights."

Mariana Trench: Deepest-ever sub dive finds plastic bag - BBC News link here
"An American explorer has found plastic waste on the seafloor while breaking the record for the deepest ever dive.
Victor Vescovo descended nearly 11km (seven miles) to the deepest place in the ocean - the Pacific Ocean's Mariana Trench.
He spent four hours exploring the bottom of the trench in his submersible, built to withstand the immense pressure of the deep.
He found sea creatures, but also found a plastic bag and sweet wrappers.
... Humanity's impact on the planet was also evident with the discovery of plastic pollution. It's something that other expeditions using landers have seen before.
Millions of tonnes of plastic enter the oceans each year, but little is known about where a lot of it ends up.
The scientists now plan to test the creatures they collected to see if they contain microplastics - a recent study found this was a widespread problem, even for animals living in the deep."

India's pollution is killing millions, yet it's not a poll agenda - Aljazeera link here
"Climate change appears in poll manifestos of leading parties for the first time, but experts say it's not enough
...India, the world's fastest growing economy, is currently holding its seven-phase general elections. Over 900 million eligible voters are expected to cast their votes in the elections, which end on May 19.
While a number of national issues, including issues of national security and economy, have been in the headlines throughout the ongoing elections, there is barely any discussion over the country's pollution crisis in the campaigns.
India's toxic air claimed 1.24 million lives in 2017 - 12.5 percent of total deaths recorded that year in the country, according to a study published in Lancet Planetary Health. The study said more Indians died due to pollution than cancer, tuberculosis, AIDS and diabetes put together.
The 2018 Global Environmental Performance Index placed India at 177 out of 180 countries, down more than 20 spots from 155 in 2014.
In March this year, another study showed that India is home to 15 of the world's 20 most polluted cities. All four satellite cities surrounding New Delhi - Gurugram, Ghaziabad, Faridabad and Noida - figured in the top six while the national capital itself, home to nearly 30 million people, was placed at 11 out of 20.
Yet, Indian politicians seeking a place in India's 543-member lower house of parliament hardly ever talk about the deadly pollution around them in their campaign speeches.
"Pollution is not an issue for political parties because these leaders are not affected by it. The prime minister's residence is spread across hectares and is full of greenery. What problem is he facing due to air pollution?" asked Priya, who goes by her first name."

Only a third of world’s great rivers remain free flowing, analysis finds - The Guardian link here
"Dams, levees, hydropower and habitat degradation behind fragmentation on huge scale, finds global assessment.
Only a third of the world’s great rivers remain free flowing, due to the impact of dams that are drastically reducing the benefits healthy rivers provide people and nature, according to a global analysis.
Billions of people rely on rivers for water, food and irrigation, but from the Danube to the Yangtze most large rivers are fragmented and degraded. Untouched rivers are largely confined to remote places such as the Arctic and Amazonia.
The assessment, the first to tackle the subject on a worldwide level, examined 12m kilometres of rivers and found that just 90 of the 246 rivers more than 1,000km (621 miles) long flowed without interruption."

Human society under urgent threat from loss of Earth's natural life - The Guardian link here
"Scientists reveal 1 million species at risk of extinction in damning UN report
Human society is in jeopardy from the accelerating decline of the Earth’s natural life-support systems, the world’s leading scientists have warned, as they announced the results of the most thorough planetary health check ever undertaken.
From coral reefs flickering out beneath the oceans to rainforests desiccating into savannahs, nature is being destroyed at a rate tens to hundreds of times higher than the average over the past 10m years, according to the UN global assessment report.
The biomass of wild mammals has fallen by 82%, natural ecosystems have lost about half their area and a million species are at risk of extinction – all largely as a result of human actions, said the study, compiled over three years by more than 450 scientists and diplomats.
Two in five amphibian species are at risk of extinction, as are one-third of reef-forming corals, and close to one-third of other marine species. The picture for insects – which are crucial to plant pollination – is less clear, but conservative estimates suggest at least one in 10 are threatened with extinction and, in some regions, populations have crashed. In economic terms, the losses are jaw-dropping. Pollinator loss has put up to $577bn (£440bn) of crop output at risk, while land degradation has reduced the productivity of 23% of global land.
The knock-on impacts on humankind, including freshwater shortages and climate instability, are already “ominous” and will worsen without drastic remedial action, the authors said.
“The health of the ecosystems on which we and other species depend is deteriorating more rapidly than ever. We are eroding the very foundations of economies, livelihoods, food security, health and quality of life worldwide,” said Robert Watson, the chair of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (Ibpes). “We have lost time. We must act now.”"

'Low rains, a heatwave. Then floods': Bad harvest pushes North Korea to the brink - The Guardian link here
"Millions of North Koreans are being forced to rely on meagre rations after the nation's worst harvest in a decade.
The country is 1.36m tonnes of food short following a series of weather disasters, compounded by longstanding international sanctions.
A UN assessment found North Koreans had been surviving on just 300g (10.5 oz) of food a day so far this year.
In previous years rations have been cut so low only during the "lean season" - the last few months before harvest.
About 70% of the North Korean population rely on food rations, according to UN figures. They have fallen from 550g in early January to 300g per person. There are fears they could be cut further before the next harvest, which is still six months away.
"It used to be they only reached this low level in July, August, and September," said Mario Zappacosta, a senior economist at the UN's Food and Agriculture Organisation (FAO), who visited North Korea last month.
"If the international community does not take action somehow, and quickly, there are some social groups who will suffer - the kids, the pregnant women, lactating mothers," he said."

‘Do it now’: UK must set zero-carbon target for 2050, say official advisers - The Guardian link here
"Committee says legally binding target is necessary, achievable and could spur global action.
The UK government must immediately set a legally binding target to cut greenhouse gas emissions to zero by 2050, its official advisers have said, signalling an end to the nation’s role in driving climate change.
Doing so will be challenging, said the Committee on Climate Change, meaning the end of petrol and diesel cars and gas boilers, less meat on plates, quadrupling clean electricity generation and planting an estimated 1.5bn trees.
It will require tens of billions of pounds of investment every year, the CCC said – about 1-2% of Britain’s GDP. But not acting would be far more costly and the changes would deliver a cleaner and healthier society, the advisers said, as well as potentially bolstering the UK economy and jobs.
The CCC’s request for urgent action comes after Labour, Scottish National party and the Welsh assembly declared a climate emergency. It also follows a week of high-profile protests by the Extinction Rebellion group and Greta Thunberg, the Swedish teenager who inspired the global school strikes, telling the UK government that its support for fossil fuels and airport expansion is “beyond absurd”.
The UK is forecast to miss existing carbon targets in 2025 and 2030. Hitting zero emissions in 2050 will require a leap in the ambition of government policy, particularly on heating and transport.
The zero emissions goal would fulfil the pledge made by the UK when it signed the Paris agreement in 2015 to limit the rise in global temperature to as close to 1.5C above pre-industrial levels as possible. In October, the world’s scientists warned of severe global impacts above this rise.
The CCC target includes flying and shipping and all greenhouse gases, and allows no offsetting of emissions abroad, making it the toughest of any major economy. The CCC said it could prove a vital catalyst in unlocking matching pledges from other countries. The current plans of the world’s nations would lead to 3C of warming and catastrophic damage.
The CCC’s recommendation was welcomed by many politicians, business leaders, energy and water companies, doctors and farmers. Some green groups, including WWF, called for zero emissions by 2045, while Extinction Rebellion activists have said 2025. The CCC said the 2050 date could be brought forward if good progress was made.
The former environment secretary John Gummer, now Lord Deben, the chair of the CCC, said the zero emissions target for 2050 must be passed into law immediately. “We [must] do it now. The urgency is not just a matter of a shortness of time, but the quicker you do it, the cheaper it is.”
Referring to the climate protests, he added: “Recent events have shown how strongly people feel.”
Chris Stark, the chief executive of the CCC, said planning to cut emissions rapidly could begin as soon as the zero emissions target was set. “I would like to see it happen as soon as possible, preferably before the big UN summit in September,” he added.
António Guterres, the UN secretary general, is demanding nations bring ambitious pledges to that summit to deliver the action needed.

UK Parliament declares climate change emergency -BBC News link here
"MPs have approved a motion to declare an environment and climate emergency.
This proposal, which demonstrates the will of the Commons on the issue but does not legally compel the government to act, was approved without a vote.
Labour leader Jeremy Corbyn, who tabled the motion, said it was "a huge step forward".
Environment Secretary Michael Gove acknowledged there was a climate "emergency" but did not back Labour's demands to declare one.
The declaration of an emergency was one of the key demands put to the government by environmental activist group Extinction Rebellion, in a series of protests over recent weeks.
Addressing climate protesters from the top of a fire engine in Parliament Square earlier, Mr Corbyn said: "This can set off a wave of action from parliaments and governments around the globe.
"We pledge to work as closely as possible with countries that are serious about ending the climate catastrophe and make clear to US President Donald Trump that he cannot ignore international agreements and action on the climate crisis." "

'Climate change 'cause of most under-reported humanitarian crises' Report says few headlines sparked by food crises that ravaged Madagascar, Ethiopia and Haiti' - The Guardian link here
"Climate change was responsible for the majority of under-reported humanitarian disasters last year, according to analysis of more than a million online news stories.
Whole populations were affected by food crises in countries ravaged by by drought and hurricanes such as Ethiopia and Haiti, yet neither crisis generated more than 1,000 global news stories each.
In Madagascar, more than a million people went hungry as corn, cassava and rice fields withered under drought and severe El Niño conditions. Almost half the country’s children have been stunted, but their suffering sparked few headlines.
Sven Harmeling, the climate change lead for Care International, which commissioned the report, said: “Not only are the people who live in the world’s poorest countries most vulnerable to climate change, but they are also the least equipped to address its increasing impacts. Media must not turn a blind eye to such crises and the role of climate change.”
Asad Rehman, the executive director of War on Want, blamed a “climate change reporting that prefers pictures of polar bears to those we are killing with our inaction"

'World's richest 1% get 82% of the wealth', says Oxfam - BBC News link here
The gap between the super rich and the rest of the world widened last year as wealth continued to be owned by a small minority, Oxfam has claimed.
Some 82% of money generated last year went to the richest 1% of the global population while the poorest half saw no increase at all, the charity said.
Oxfam said its figures - which critics have queried - showed a failing system.
It blamed tax evasion, firms' influence on policy, erosion of workers' rights, and cost cutting for the widening gap.
Oxfam has produced similar reports for the past five years. In 2017 it calculated that the world's eight richest individuals had as much wealth as the poorest half of the world.
This year, it said 42 people now had as much wealth as the poorest half, but it revised last year's figure to 61. Oxfam said the revision was due to improved data and said the trend of "widening inequality" remained."

‘More Glaciers in East Antarctica Are Waking Up’ - NASA Earth Observatory link here
“If the thick ice cover over East Antarctica were to melt, it would reshape coastlines around the world through rising sea levels. But scientists have long considered the eastern half of the continent to be more stable than West Antarctica. Now new maps of ice velocity and elevation show that a group of glaciers spanning one-eighth of the East Antarctic coast have been losing some ice over the past decade.
Glaciologists have warned in recent years that Totten Glacier—the fastest moving ice in East Antarctica—appears to be retreating due to warming ocean waters. Totten contains enough ice to raise sea level by at least 3.4 meters (11 feet). Researchers have now found that four glaciers to the west of Totten, plus a handful of smaller glaciers farther east, are also losing ice.”

'Global food system is broken, say world’s science academies' - The Guardian link here
“Radical overhaul in farming and consumption, with less meat eating, needed to avoid hunger and climate catastrophe. The global food system is broken, leaving billions of people either underfed or overweight and driving the planet towards climate catastrophe, according to 130 national academies of science and medicine across the world. Providing a healthy, affordable, and environmentally friendly diet for all people will require a radical transformation of the system, says the report by the InterAcademy Partnership (IAP). This will depend on better farming methods, wealthy nations consuming less meat and countries valuing food which is nutritious rather than cheap. The report, which was peer reviewed and took three years to compile, sets out the scale of the problems as well as evidence-driven solutions. The global food system is responsible for a third of all greenhouse gas emissions, which is more than all emissions from transport, heating, lighting and air conditioning combined. The global warming this is causing is now damaging food production through extreme weather events such as floods and droughts.”

'Is An Oil Supply Crunch Inevitable?' - NASDAQ link here
"Global oil demand will peak by 2040, according to a new report, although oil supply shortages could emerge before then.
... On the supply side, the U.S. accounts for about three-quarters of the increase in global oil production through 2025, an astounding figure. But shale starts to fade in terms of importance after that date, with OPEC regaining its position as the main source of supply growth.
In fact, the IEA said that even as U.S. shale continues to grow, there is a danger in the oil market becoming overly dependent on shale. After the oil price crash in 2014, the oil industry severely cut back on spending. That has translated it into fewer discoveries and fewer new projects being developed.
... Overall, the IEA’s message is that oil demand will grow in the medium-term before flattening out and ultimately hitting a peak by 2040. But in the interim, the shortfall in spending by oil companies could translate into a supply shortage in the mid-2020s."

'Oil Market Reliance on U.S. Shale Potential Is Risky, IEA Says' - Blombergy link here
"There’s a risk the world is becoming too reliant on the rapid growth of U.S. shale oil, its foremost energy adviser has warned.
Without a raft of new approvals for non-shale projects, oil production from U.S. shale plays must more than triple by 2025, to an eye-popping 15 million barrels a day, to satisfy global demand, according to the International Energy Agency’s latest World Energy Outlook.
That’s as upstream projects, including large deepwater developments and those targeting sandstone reservoirs onshore, have been affected by the industry only just emerging from a worst-in-a-generation slump.
The trouble is, it’s unlikely shale can grow to that extent. Even if producers are able to overcome infrastructure bottlenecks that have muted growth this year, they’d need to invest far more and bring in a higher number of rigs than they did when oil prices peaked at $115 a barrel in 2014."

'New Arctic Lakes Could Soon Be a Major Source of Atmospheric Methane' - NASA link here
“For centuries, a massive store of carbon has been locked underground in the Arctic's permanently frozen soil known as permafrost. As Earth's climate continues to warm, that carbon has begun to leach into the atmosphere, the result of microbes waking up and digesting once-frozen organic materials.
A new NASA-funded study focuses on a mechanism that could accelerate the release of this atmospheric carbon, the result of thermokarst lakes. These lakes form when thawing permafrost causes the ground to slump, creating a depression that collects rain and snowmelt and perpetuates a cycle of further permafrost thaw.”

‘Sea level rise due to Antarctic ice melt has ‘tripled over past five years’ - CarbonBrief link here
The rate of sea level rise resulting from the melting of the Antarctic ice sheet has tripled over the past five years, according to new research from a global team of scientists. The study, published in Nature, finds that ice loss from Antarctica has caused sea levels to rise by 7.6mm from 1992-2017, with two fifths of this increase occurring since 2012. At a press conference held in London, scientists said the results suggest that Antarctica has become “one of the largest contributors to sea level rise”. A glaciologist not involved in the paper tells Carbon Brief that the findings show “there now should be no doubt that Antarctica is losing ice due to regional climate change, likely linked to global warming”.

"The Trump Administration today moved to weaken fuel economy standards for automobiles, saying the current ones are inappropriate and wrong. The long-anticipated move is a win for auto manufacturers, which had lobbied for lower fuel-economy standards. It's also a rejection of one of former President Barack Obama's biggest efforts to combat climate change by curbing greenhouse gas emissions. In making the announcement, Scott Pruitt, head of the Environmental Protection Agency, accused Obama of making incorrect assumptions when setting the standards, which led to them being set "too high." The Obama administration, working with California, aimed to nearly double the fleet wide average fuel economy for passenger cars and SUVs to more than 50 miles per gallon by 2025."

‘Huge oil spill left after burning tanker sinks off China’ - BBC News link here
“Chinese ships are racing to clean up a giant oil spill after an Iranian tanker sank in the East China Sea. The 120 sq km (46 sq mile) oil slick is thought to be made up of heavy fuel that was used to power the vessel. The Sanchi oil tanker sank on Sunday and officials say all its crew members are dead. It was carrying 136,000 tonnes of ultra-light crude oil from Iran which generates a toxic underwater slick that would be invisible from the surface. Both the fuel and the ultra-light oil could cause devastating damage to marine life. The Sanchi and a cargo ship collided 260km (160 miles) off Shanghai on 6 January, with the tanker then drifting south-east towards Japan. It caught fire after the collision and burnt for more than a week before sinking off China's east coast.”

'Extraordinary' levels of pollutants found in 10km deep Mariana trench - The Guardian link here
"Presence of manmade chemicals in most remote place on planet shows nowhere is safe from human impact, say scientists,
Scientists have discovered “extraordinary” levels of toxic pollution in the most remote and inaccessible place on the planet – the 10km deep Mariana trench in the Pacific Ocean.
Small crustaceans that live in the pitch-black waters of the trench, captured by a robotic submarine, were contaminated with 50 times more toxic chemicals than crabs that survive in heavily polluted rivers in China.
“We still think of the deep ocean as being this remote and pristine realm, safe from human impact, but our research shows that, sadly, this could not be further from the truth,” said Alan Jamieson of Newcastle University in the UK, who led the research.
“The fact that we found such extraordinary levels of these pollutants really brings home the long-term, devastating impact that mankind is having on the planet,” he said.
Jamieson’s team identified two key types of severely toxic industrial chemicals that were banned in the late 1970s, but do not break down in the environment, known as persistent organic pollutants (POPs). These chemicals have previously been found at high levels in Inuit people in the Canadian Arctic and in killer whales and dolphins in western Europe."

"There is no reason at all why capitalism could not survive without slow or even no growth.... I think it's perfectly possible that economic growth cannot go on at its current rate forever. This does not mean that productivity will cease to increase our quality of life; it means that people might find it increasingly costly to tum productivity into the kinds of things they are now accustomed to buying with their earnings. ..It is possible that the United States and Europe will find that, as the decades go by, either continued growth will be too destructive to the environment and they are too dependent on scarce natural resources, or that they would rather use increasing productivity in the form of leisure .... There is nothing intrinsic in the system that says it cannot exist happily in a stationary state"
