A pair of scientific studies find we can still probably avert extreme sea level rise -- but also show how little scientists still understand about the biggest threat, Antarctica.

If world leaders and policy makers cant find a way to reduce emissions and limit warming to 2 degrees Celsius, new models suggest runaway Antarctic ice losses will trigger dramatic sea level rise.

New Modeling of the Antarctic Ice Sheet Shows Rapid and Unstoppable Sea Level Rise if Paris Agreement Targets Overshot Study led by UMass Amherst’s Rob DeConto is the first to use physics-based model of ice sheet to test Paris Agreement targets May 5, 2021 Helheim Glacier.

New research, published today in Nature, models the impacts on the Antarctic Ice Sheet of several different global warming scenarios and the resulting...

If the Paris Agreement Fails, Sea Levels Could Rise 10 Metres Share Photo: Chris Larsen, AP If we keep on the path we’re on, Antarctica might be really, truly toast. A new study shows that the continent might hit a tipping point within this century if we don’t keep warming in check, and we might be in for dozens of feat of sea level rise as a result. The study, published on Wednesday in Nature, uses computer models to see how the Antarctic ice sheet would respond if the globe warmed 1.5 deg...

ambitiously slash carbon emissions in the coming decades. Sea levels, of course, won’t instantly rise by tens of feet: Miles-thick ice sheets take many centuries to thousands of years to melt. But, critically, humanity is already setting the stage for a relatively quick return to Pliocene climes, or climes at least significantly warmer than now. It’s happening fast. When CO2 naturally increases in the atmosphere, pockets of ancient air preserved in ice show this CO2 rise happens gra...
