From Financial Times: Antarctica is changing fast, including sections of the massive ice sheet that covers it. This holds so much water that if it ever melted completely, global sea levels would rise by nearly 60m. The race to understand Antarctica has become more urgent. Also watch, the documentary ‘The Antarctica Challenge: A Global Warning.’

From Grist.org: Two Antarctic glaciers act as a plug holding back enough ice to pour 11 feet of sea-level rise into the world’s oceans —an amount that would submerge every coastal city on the planet. Finding out how fast these glaciers will collapse is one of the most important scientific questions in the world today.
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 The Daily Conversation: This video shows the top 10 countries threatened by the 6 meter sea level rise we are almost guaranteed to see in the not-too-distant future, according to the projected pace of global warming and ice melt in Greenland and Antarctica. India is No. 3 on the list, and China No. 1.
In West Antarctica, a huge ice shelf called Larsen C has developed a rift 175 kilometres long and half-a-kilometre wide, which could soon set loose an iceberg the size of Haryana, at over 5,000 sq. km. We need to pay more attention because it could potentially gravely impact India in the near and long term.
Newsner reports: During a National Geographic-commissioned photo expedition to the Arctic, photographer James Balog and his team were examining a glacier when their cameras caught something out of the ordinary. This rare footage has gone on record as the largest glacier calving event ever captured on film, and presents a dire warning of things to come.
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.

Scroll.in It’s hot out. Everywhere. Even at the poles of the earth. We already know that 2014 was thewarmest year on record and also that sea surface temperatures reached a record high. This has meant storms, droughts, raised sea levels and heat waves and other extreme weather events that have been caused by global warming. Among the most
OMG… Greenland’s ice sheets are melting fast The Guardian UK An urgent attempt to study the rate at which Greenland’s mighty ice sheets are melting has been launched by Nasa. The aim of the six-year project, called Oceans Melting Greenland (OMG), is to understand how fast the world’s warming seas are now eroding the edges
Continued destruction of Earth’s plant life places humans in jeopardy Science Daily Unless humans slow the destruction of Earth’s declining supply of plant life, civilization like it is now may become completely unsustainable, according to a paper published recently by University of Georgia researchers in the Proceedings of the National Academy of Sciences. “You can think
Arctic sea ice extent hits record low for winter maximum The Guardian, UK Arctic sea ice has hit a record low for its maximum extent in winter, which scientists said was a result of climate change and abnormal weather patterns. The US National Snow and Ice Data Centre (NSIDC) said on Thursday that at its
