“Precipitous” fall in Antarctic sea ice since 2014 revealed – “The rapid decline has caught us by surprise and changes the picture completely”

By Damian Carrington 1 July 2019 (The Guardian) – The vast expanse of sea ice around Antarctica has suffered a “precipitous” fall since 2014, satellite data shows, and fell at a faster rate than seen in the Arctic. The plunge in the average annual extent means Antarctica lost as much sea ice in four years […]

Global sea level rise with the Thwaites Glacier and the ice of the West Antarctic Ice Sheet. Graphic: PRI

Scientists race against time to find out if Antarctica’s Thwaites Glacier is doomed – “This is where rapid change is really happening, and we’re actually standing and looking at the bit that’s rapidly changing”

By Carolyn Beeler 13 May 2019 (PRI) – Peter Sheehan, an oceanographer on the Nathaniel B. Palmer, was one of the first people on Earth to get this view of Thwaites Glacier — the part that juts out to sea. He’s pored over plenty of Google images of ice shelves, but there’s nothing like the […]

Sea level rise could displace millions of people within two generations

By Jonathan Bamber and Michael Oppenheimer 20 May 2019 (The Conversation) – Antarctica is further from civilisation than any other place on Earth. The Greenland ice sheet is closer to home but around one tenth the size of its southern sibling. Together, these two ice masses hold enough frozen water to raise global mean sea […]

A quarter of West Antarctic ice is now unstable – “A wave of thinning has spread rapidly across some of Antarctica’s most vulnerable glaciers, and their losses are driving up sea levels around the planet”

A quarter of West Antarctic ice is now unstable – “A wave of thinning has spread rapidly across some of Antarctica’s most vulnerable glaciers, and their losses are driving up sea levels around the planet”

16 May 2019 (University of Leeds) – In only 25 years, ocean melting has caused ice thinning to spread across West Antarctica so rapidly that 24 percent of its glacier ice is now affected, according to a new study. By combining 25 years of European Space Agency satellite altimeter measurements and a model of the […]

Ozone hole mystery: Illegal sales of insulating chemical in China found to be source of rising CFC-11

By Matt McGrath 8 July 2018 (BBC News) – Cut-price Chinese home insulation is being blamed for a massive rise in emissions of a gas, highly damaging to the Earth’s protective ozone layer. The Environmental Investigations Agency (EIA) found widespread use of CFC-11 in China, even though the chemical was fully banned back in 2010. […]
