What is permafrost? What happens when permafrost thaws? This animation, based on research by scientists at the Alfred Wegener Institute, answers these questions. Understanding this problem, and its connection to global climate change, is of vital importance at a time when the thawing Arctic tundra is creating massive craters and bringing back diseases like anthrax.
From The Guardian: In 2006, former U.S. Vice-President Al Gore triggered a worldwide debate about climate change with his Oscar-winning documentary, An Inconvenient Truth. Now, he’s back with a rousing follow-up for the age of climate change denial under Trump. Fellow climate champion and U.S. presidential candidate Bernie Sanders recently discussed the film with Gore.
It is not often that an article about climate change becomes the most hotly debated item on the internet. But David Wallace-Wells’ lengthy essay published in New York Magazine did exactly that. The full text of the essay –admittedly a worst-case scenario- which has kicked up a firestorm of debate online, along with selected responses.
The Washington Post reports: Scientists have announced that a much-anticipated break at the Larsen C ice shelf in Antarctica has occurred, unleashing a massive iceberg that is more than 2,200 square miles in area and weighs a trillion tons. Also, Nagraj Adve on why India must heed the cracking of this Haryana-sized Antarctic ice shelf.
From Common Dreams: Humanity has just three years left to drastically reduce greenhouse gas emissions before risking a climate-safe world. After roughly 1°C of global warming driven by human activity, ice sheets are melting, summer sea ice is disappearing in the Arctic and coral reefs dying from heat stress— entire ecosystems are starting to collapse.
From Forbes Magazine: With all of the knowledge of future mapping, do the world’s financial leaders know something we don’t? Consider how many of the richest families have been grabbing up massive amounts of farmland around the world. All property far away from coastal areas and in locations conducive to self-survival, farming and coal mining.
Dave Lindorff writes: The concern is that if the Arctic Ocean waters were to warm even slightly, as they will do as the ice cap vanishes in summer, at some point the clathrates which have currently trapped massive amounts of methane will suddenly dissolve releasing tens of thousands of gigatons of methane in huge bursts.
Sonam Wangchuk, the real life inspiration of the character “Phunsuk Wangdu” in Bollywood hit “3 idiots”, recently led an expedition to Sikkim’s Lhonak lake, which has been declared dangerous. Their objective was to install a siphoning system to drain the lake and prevent climate disaster, probably the first project of its kind in the world.
Chris Mooney reports: A recent report showed Greenland lost 1 trillion tons of ice mass between 2011 and 2014. A new NASA study shows that key areas where glaciers have been melting have actually experienced a reduction in gravitational pull, which has in turn reduced sea levels, confirming an age old prediction of climate science.
Sayantan Bera reports: Data from the ministry of water resources show that in end March, water levels in 91 major reservoirs in the country was at just 25% of capacity—30% lower than last year, and 25% less than the average storage in a decade. The situation is acute in the western parts of the country.
The world may be much closer to an abrupt and catastrophic climate shift than previously thought. That’s the warning from modern climate science pioneer James Hansen. His latest research suggests that polar ice sheet disintegration may cause sea level rise enough to drown coastal cities, not in a few centuries, but in a few decades.
The Centre has proposed modification of green laws to impose a fine up to Rs 20 crore on major environment violators, who would also have to pay a daily fine of Rs 1 crore if the damage continues. Another green law will prevent violators from taking shelter under a legal cover for non-payment of fines.
If any of us have fixed geographical notions of the nation-state, the rise and fall of sea levels everywhere ought to give us pause. Not just in warnings about the future, but also lessons from the past. Once, England and France were contiguous landmass… our borders are drawn not by us, but by the oceans.
