Increasing Antarctic snowfall may offset sea-level rise

From THE EARTH INSTITUTE AT COLUMBIA UNIVERSITY By mid-century, more Antarctic snowfall may help offset sea-level rise Increasing precipitation masked by natural variability — for now When Antarctica’s air temperature rises, moisture in the atmosphere increases. That should mean more snowfall on the frozen continent. So why hasn’t that trend become evident in Antarctica’s surface…

Expanding Antarctic sea ice linked to natural variability

From the NATIONAL CENTER FOR ATMOSPHERIC RESEARCH/UNIVERSITY CORPORATION FOR ATMOSPHERIC RESEARCH BOULDER — The recent trend of increasing Antarctic sea ice extent — seemingly at odds with climate model projections — can largely be explained by a natural climate fluctuation, according to a new study led by the National Center for Atmospheric Research (NCAR). The…
