Polar Regions Will See More Snow Over Next Century, Less Everywhere Else

A newly-developed National Oceanic and Atmospheric Administration (NOAA) climate model predicts that increasing carbon dioxide (CO2) levels will lead to less snowfall in most areas of the world – including the United States – over the next 100 years.

In fact, research conducted by Sarah Kapnick of the Princeton University Atmospheric and Oceanic Sciences (AOS) program and Thomas Delworth, a senior physical scientist at the NOAA’s Geophysical Fluid Dynamics Laboratory (GFDL), forecasts that only the polar regions and the Earth’s highest altitudes will receive more snow 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,” Catherine Zandonella, Office of the Dean for Research at the New Jersey-based university, reported on Friday.

The AOS/GFDL model revealed that atmospheric CO2 levels could double later on this century, leading to considerable reductions in winter precipitation is most regions. According to Zandonella, in North America, the northeastern coast and the mountainous regions of the western part of the continent will be the hardest hit, with snowfall levels dropping to less than half of their current levels.
