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.
