Warming Ocean Layers Will Prove Disastrous for Ice Sheets

Warming Ocean Layers Will Prove Disastrous for Ice Sheets

“If you put an ice cube in a warm room, it will melt in several hours. But if you put an ice cube in a cup of warm water, it will disappear in just minutes.” This is the problem facing the Polar ice sheets over the rest of the 21st century, according to new research which shows that warming of the ocean’s subsurface layers will speed up the melting of the ice sheets by melting underwater of Greenland and Antarctica. The research, led by the University of Arizona, shows that such melting will only increase the speed at which the sea level increases. “To my knowledge, this study is the first to quantify and compare future ocean warming around the Greenland and the Antarctic ice sheets using an ensemble of models,” said lead author Jianjun Yin, a UA assistant professor of geosciences, although, we reported here at Planetsave the other day about a similar study which looked at...
