Polar ice sheets are melting and contributing to a global rise in sea-level. This study looked at changes in Greenland’s ice sheet from April 2002 to August 2011 and found that active areas of ice loss were concentrated on the southeastern and northwestern coasts, with ice mass in the center of Greenland steadily increasing over the decade.

Efforts to predict North Atlantic hurricane activity should focus on improving the ability of global climate models to capture the processes that control patterns of sea surface temperature change through better modeling of cloud physics, atmospheric convection, oceanic processes, the role of aerosols, and overall improvements in spatial resolution of the models, according to a new study by Gabriele Villarini, a postdoctoral research associate in the Department of Civil and Environmental Engineering at Princeton University, and Gabriel A. Vecchi, a scientist at the U.S. National Oceanic and Atmospheric Administration’s Geophysical Fluid Dynamics Laboratory in Princeton.
