Sea Level Rise Could Be Twice As High As Projected

University of Buffalo
Lead author: Beata Csatho
Where published: Journal of Glaciology

If current climate models from the IPCC included data from ice dynamics in Greenland, the sea level rise estimated during this century could be twice as high as what they are currently projecting ... the changes we are seeing now are bigger than can be accounted for by normal, annual perturbations in climate

Climate May Undergo Sudden Shifts

University of East Anglia

Tim Lenton
Where published:
Proceedings of the National Academy of Sciences

Our findings suggest that a variety of tipping elements could reach their critical point within this century under human-induced climate change ... The greatest threats are tipping of the Arctic sea-ice and the Greenland ice sheet, and at least five other elements could surprise us by exhibiting a nearby tipping point.

Antarctic Ice Loss Speeds Up

NASA Jet Propulsion Laboratory, U. California
Lead author: Eric Rignot
Where published: Nature Geoscience

Ice loss in Antarctica increased by 75 percent in the last 10 years due to a speed-up in the flow of its glaciers and is now nearly as great as that observed in Greenland, according to a new, comprehensive study
