By MICHAEL FIELD26 February 2011 (Stuff) – An Antarctic ice shelf used as a runway is breaking away, forcing an emergency airlift to close summer operations on the continent. The situation is being complicated by the Christchurch quake which is limiting operations at Christchurch Airport. Staff at New Zealand’s Scott Base and the US’s McMurdo […]
24 February 2011 (AFP) – LIMA — A glacier on Peru’s Huaytapallana Mountain shed half its surface ice in just 23 years, officials said Wednesday, reinforcing concerns of climate change’s growing threat to fresh water resources. “Recent scientific studies indicate that between June 1983 and August 2006, the glacier has lost 50 percent of its […]
By Isabel de Bertodano15 February 2011 AMECAMECA, Mexico — Glaciers that crown a Mexican volcano could disappear by 2015 with scientists pointing to global warming as a chief cause of their demise. Until recently, the glacial field on Iztaccihuatl, a dormant volcano and one of two white-capped peaks that can be seen from Mexico City, […]
By Yereth Rosen; editing by Steve Gorman and Greg McCuneSat Feb 12, 2011 12:43pm EST ANCHORAGE, Alaska (Reuters) – Thawing permafrost is triggering mudslides onto a key road traveled by busloads of sightseers. Tall bushes newly sprouted on the tundra are blocking panoramic views. And glaciers are receding from convenient viewing areas, while their rapid […]
Anomaly map of Greenland melting days for 2010 derived from passive microwave data. Hatched regions indicate where MAR-simulated meltwater production exceeds the mean by at least two standard deviations. Abstract: Analyses of remote sensing data, surface observations and output from a regional atmosphere model point to new records in 2010 for surface melt and albedo, […]
ScienceDaily (Jan. 26, 2011) — Hotter summers may not be as catastrophic for the Greenland ice sheet as previously feared and may actually slow down the flow of glaciers, according to new research. A letter published in Nature on 27 January 2011 explains how increased melting in warmer years causes the internal drainage system of […]
The figure shows the standardized melting index anomaly for the period 1979 – 2010. In simple words, each bar tells us by how many standard deviations melting in a particular year was above the average. For example, a value of ~2 for 2010 means that melting was above the average by two times the ‘variability’ […]

Caption by Kathryn Hansen and Michael CarlowiczJanuary 19, 2011 In October 2009, a series of flights over Antarctica led to the discovery of a hidden feature beneath a floating ice shelf. Scientists participating in NASA’s Operation IceBridge mapped the water depth and seafloor topography beneath Pine Island Glacier and found a deepwater channel—a likely pathway […]
By Alister Doyle, Environment Correspondent; editing by David StampOSLO | Sun Jan 16, 2011 8:45pm GMT (Reuters) – Shrinking ice and snow cover in the Northern Hemisphere is reflecting ever less sunshine back into space in a previously underestimated mechanism that could add to global warming, a study showed. Satellite data indicated that Arctic sea […]
