Forecast is for more snow in polar regions, less for the rest of us (Journal of Climate) Posted on February 22, 2013

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.

About Mike
A resident of the “30 square miles surrounded by reality,” I spend most of my time teaching economics and statistics to undergraduate students. I enjoy, naturally, economics and business, but also science (I was once an astronomical observatory assistant), politics, photography, food, travel and sports. Madison has grown quite a bit since 1978 when Governor Lee Dreyfus made that remark. According to Wikipedia, Madison is 67.3 square miles of land and 16 square miles of water. Visit for one of my favorite views of the isthmus. Or, why not come visit us!
