At both poles, ice melt is speeding up
U. LEEDS (UK) / CALTECH (US) — Ice sheet melting has increased over time and, altogether, Greenland and Antarctica are now losing more than three times as much ice as they were in the 1990s. (more…)

More melting may slow glacier flow
U. LEEDS (UK) — Hotter summers may not be as catastrophic for the Greenland ice sheet as previously feared and may actually slow down the flow of glaciers. (more…)

Arctic cores signal ‘unique’ climate shift
U. COLORADO (US)—An analysis of sediment cores indicates that biological and chemical changes occurring at a remote Arctic lake are unprecedented over the past 200,000 years and likely are the result of human-caused climate change. (more…)
