Calving icebergs cause earthquakes in Greenland and Antarctica

By Chris Mooney 25 June 2015 (Washington Post) – If Greenland goes, it is becoming clear that it won’t go quietly. Scientists have already documented entire meltwater lakes vanishing in a matter of hours atop the vast Greenland ice sheet, as huge crevasses open beneath them. And now, they’ve cast light on the mechanisms behind […]

Ancient Antarctic ice shelf nearing complete collapse – ‘What is really surprising about Larsen B is how quickly the changes are taking place’

By Carol Rasmussen14 May 2015 (NASA/JPL) – A new NASA study finds the last remaining section of Antarctica’s Larsen B Ice Shelf, which partially collapsed in 2002, is quickly weakening and is likely to disintegrate completely before the end of the decade. A team led by Ala Khazendar of NASA’s Jet Propulsion Laboratory in Pasadena, […]

Global warming begins in Arctic and moves southward, half-mile slice of West Antarctica ice core reveals

12 May 2015 (SDSU) – SDSU scientists analyzed a half-mile slice of Western Antarctica ice core to help determine that climate change begins in the Arctic and moves southward, according to chemistry professor Jihong Cole-Dai of the SDSU Ice Core and Environmental Chemistry Lab. Since 2006, the SDSU research team have been part of a […]

Sea levels are rising at faster clip as polar melt accelerates, new study shows

By Joby Warrick11 May 2015 (Washington Post) – Global sea levels are climbing at a faster rate than previously thought, according to a new analysis that underscores scientists’ concerns about the impact of melting glaciers and ice sheets near the Earth’s poles. The new research published Monday in the journal Nature Climate Change shows that […]

The big melt: Antarctica’s retreating ice may re-shape Earth – ‘We have to stop it; or we have to slow it down as best as we can’

By Luis Andres Henao and Seth Borenstein28 February 2015 CAPE LEGOUPIL, Antarctica (Associated Press) – From the ground in this extreme northern part of Antarctica, spectacularly white and blinding ice seems to extend forever. What can’t be seen is the battle raging thousands of feet (hundreds of meters) below to re-shape Earth. Water is eating […]

Image of the Day: Satellite view of rift propagation across Larsen C ice shelf, January 2015

ABSTRACT: An established rift in the Larsen C Ice Shelf, formerly constrained by a suture zone containing marine ice, grew rapidly during 2014 and is likely in the near future to generate the largest calving event since the 1980s and result in a new minimum area for the ice shelf. Here we investigate the recent […]

Antarctic ice loss tripled in the last 10 years – ‘The mass loss of these glaciers is increasing at an amazing rate’

3 December 2014 (AFP) – The melt rate of glaciers in the fastest-melting part of Antarctica has tripled over the past decade, researchers said Tuesday in an analysis of the past 21 years. Glaciers in the Amundsen Sea in West Antarctica are losing ice faster than another part of Antarctica and are the biggest contributor […]

Melting Away: Beautiful polar photos tell a haunting story about global warming – ‘I stopped going because it felt so futile’

By Jakob Schiller  11 November 2014 (Wired) – When Camille Seaman started photographing icebergs and other arctic wonders, she wasn’t thinking about climate change. She simply found the frozen landscape and white vistas visually stunning. Still, you can’t help but associate her images with the ongoing conversation about climate change. Seaman, 45, says she too […]

Sebastião Salgado: His camera takes us to the world ‘We must preserve’

By Rena Silverman19 September 2014 (NPR) – They’re silvery and stunning — and their beauty bears a message. “Genesis” is a new exhibit of more than 200 black-and-white images from the noted Brazilian photographer Sebastiao Salgado. He wants to show us what the world and its peoples look like now, how climate change has already […]

Greenland ice loss doubles from late 2000s – Greenland and Antarctica together are losing 500 cubic kilometers of ice each year – ‘To us, that’s an incredible number’

By Jonathan Amos20 August 2014  (BBC News) – A new assessment from Europe’s CryoSat spacecraft shows Greenland to be losing about 375 cu km of ice each year. Added to the discharges coming from Antarctica, it means Earth’s two big ice sheets are now dumping roughly 500 cu km of ice in the oceans annually. […]
