Greenland’s melting ice sheet will likely contribute almost a foot to global sea level rise by the end of the century.
Well, there are several sources of sea level rise. One that’s underappreciated is the thermal expansion of the oceans. As we warm the atmosphere, we warm the water, and it expands, just like most things. The second-largest cause of sea level rise is now Greenland. It used to be the small glaciers. And by “small,” we mean those in the Alps, in the Himalayas, in Alaska. But Greenland is overtaking that.
Well, you know, each one of these studies shows things to be just a little bit worse than we hoped. Antarctica right now is a big question mark. We don’t want it to get a lot worse. So, the question is: Well, will it? And a similar study should be done there. The world’s small glaciers are melting at just an unprecedented rate and will continue to be a major factor in sea level rise. You know, we have to think about the climate change that’s still coming.

Sea levels expected to rise due to irreversible melting of a Greenland ice sheet - KCBS Radio: On-DemandA huge sheet of ice in Greenland is melting at a rate that couldn't be stopped even if all greenhouse gas emissions halted across the globe. A newly published paper predicts that more than 3% of that ice sheet will melt between now and the end of the century, triggering almost a foot of sea level rise. For more, KCBS Radio news anchor Liz Saint John spoke with Richard Alley, Pennsylvania State University geosciences professor and expert on ice sheets.
