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 […]
By Jonathan HarwoodJanuary 14, 2011 Scientists have discovered more evidence of global warming after the sun rose two days early in Greenland, apparently because melting glaciers have lowered the horizon. The polar night usually ends on January 13, but this year residents of Ilulissat, the third largest settlement in Greenland, were surprised to see dawn […]
By Johann HariMonday, Jan. 10, 2011, at 6:51 AM ET When Jonathan Watts was a child, he was warned: “If everyone in China jumps at exactly the same time, it will shake the earth off its axis and kill us all.” Three decades later, he stood in the gray sickly smog of Beijing, wheezing and […]
New paper in Nature Geoscience examines inertia of carbon dioxide emissions Contact: Jennifer Myers, myers@ucalgary.ca, University of Calgary 9-Jan-2011 New research indicates the impact of rising CO2 levels in the Earth’s atmosphere will cause unstoppable effects to the climate for at least the next 1000 years, causing researchers to estimate a collapse of the West […]
