OMG measurements of Greenland give us a glimpse of future sea rise | John Abraham

The Oceans Melting Greenland project is taking important measurements to determine how fast sea levels will rise

If you meet a group of climate scientists, and ask them how much sea levels will rise by say the year 2100, you will get a wide range of answers. But, those with most expertise in sea level rise will tell you perhaps 1 meter (a little over three feet). Then, they will immediately say, "but there is a lot of uncertainty on this estimate." It doesn't mean they aren't certain there will be sea level rise - that is guaranteed as we add more heat in the oceans. Here, uncertainty means it could be a lot more or a little less.

Why are scientists not certain about how much the sea level will rise? Because there are processes that are occurring that have the potential for causing huge sea level rise, but we're uncertain about how fast they will occur. Specifically, two very large sheets of ice sit atop Greenland and Antarctica. If those sheets melt, sea levels will rise hundreds of feet.
