Ice Age Melting Teaches Us About the Future


CLaSP Associate Professor Jeremy Bassis’s ice dynamics work on the role the ocean plays in ice sheet melting was covered in Mashable.


Excerpt From Original Article:

New findings from the University of Michigan explain an Ice Age paradox and add to the mounting evidence that climate change could bring higher seas than most models predict.

The study, published in Nature, shows how small spikes in the temperature of the ocean, rather than the air, likely drove the rapid disintegration cycles of the expansive ice sheet that once covered much of North America.

The behavior of this ancient ice sheet — called Laurentide — has puzzled scientists for decades because its periods of melting and splintering into the sea occurred at the coldest times in the last Ice Age. Ice should melt when the weather is warm, but that’s not what happened.
