By Wynne Parry, LiveScience Senior Writer17 April 2011 In the high latitudes, climate change projections must take a new factor into account: Ice. In the Arctic, the loss of sea ice is likely to have dramatic repercussions, including greater erosion, which can present problems for the people and economic activity in this region, according to […]
Caption by Mike Carlowicz, with background from Alan BuisMarch 26, 2011 According to a new NASA-funded satellite study, the Greenland and Antarctic ice sheets are losing mass at an accelerating pace and are overtaking ice loss from mountain glaciers and ice caps to become the dominant contributor to global sea level rise. The graph above […]
ScienceDaily (Mar. 8, 2011) — The Greenland and Antarctic ice sheets are losing mass at an accelerating pace, according to a new NASA-funded satellite study. The findings of the study — the longest to date of changes in polar ice sheet mass — suggest these ice sheets are overtaking ice loss from Earth’s mountain glaciers […]
Caption by Holli Riebeek24 February 2011 How could melting ice thousands of miles away possibly affect you? A recent study published in Nature Geoscience provides one answer to that question. Mark Flanner at the University of Michigan and his collaborators used satellite data to measure how much changes in snow and ice in the Northern […]
February 21, 2011 (PhysOrg) – The contribution of Greenland to global sea level change and the mapping of previously unknown basins and mountains beneath the Antarctic Ice Sheet are highlighted in a new film released by Cambridge University this morning. The work of glaciologist Professor Julian Dowdeswell, Director of Cambridge University’s Scott Polar Research Institute, […]
Planktic foraminiferal data and temperature reconstructions of upper Atlantic Water in the eastern Fram Strait over the past ~2100 years from sediment core MSM5/5-712-1. Thin lines are raw data, bold lines are three-point running means. Black triangles on the age scale mark calibrated accelerator mass spectrometry 14C ages. (A) Fluxes of polar and subpolar planktic […]
By Alister Doyle, Environment Correspondent; editing by Ralph BoultonFri Jan 28, 2011 5:33am EST OSLO (Reuters) – A North Atlantic current flowing into the Arctic Ocean is warmer than for at least 2,000 years in a sign that global warming is likely to bring ice-free seas around the North Pole in summers, a study showed. […]
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’ […]
