Forecast is for more snow in polar regions, less for the rest of us (Journal of Climate)

By Cather­ine Zan­donella, Office of the Dean for Research

A new cli­mate model pre­dicts an increase in snow­fall for the Earth’s polar regions and high­est alti­tudes, but an over­all drop in snow­fall for the globe, as car­bon diox­ide lev­els rise over the next century.

The decline in snow­fall could spell trou­ble for regions such as the west­ern United States that rely on snowmelt as a source of fresh water.

The pro­jec­tions are the result of a new cli­mate model devel­oped at the National Oceanic and Atmos­pheric Admin­is­tra­tion (NOAA) Geo­phys­i­cal Fluid Dynam­ics Lab­o­ra­tory (GFDL) and ana­lyzed by sci­en­tists at GFDL and Prince­ton Uni­ver­sity. The study was pub­lished in the Jour­nal of Climate.
