Phys.org  September 13, 2021 A team of researchers in the US (MIT, Woods Hole Oceanographic Institution, University of Arizona, University of Hawaii, Desert Research Institute) collected glacial ice core samples from nearly 50 sites spanning the Greenland ice sheet to reconstruct changes in windiness across the North Atlantic dating back to the eighth century. Model projections forecast a northward migration of the North Atlantic jet stream which could render the jet stream significantly different within a matter of decades. The ice core layers tell us about how much precipitation fell each year and about the temperatures that airmasses were exposed […]
