New study in Nature reveals rapid global temperature redistribution

School of Earth and Climate Sciences Professor Karl Kreutz, along with former UMaine graduate students Bess Koffman, Dan Breton, and Dominic Winski and Honors student Eliza Kane, participated in a recently published study of the West Antarctic Ice Sheet divide core. The study reveals that abrupt climate change that began in Greenland spread in ~200 years to the Antarctic, with ocean currents responsible for transferring the heat.

In that same issue is a paper co-authored by Kreutz’s former UMaine Honors student Matthew Kohler, now at the University of Washington. Matt’s study uses nitrogen isotopes to evaluate the origin of biological nitrogen fixation billions of years ago in Earth’s history.
