Winter Climate Change

Global warming affects weather in all seasons. Hubbard Brook scientists have measured winter conditions for over five decades and learned that shorter periods of snow and ice cover are forcing significant changes in the structure and function of Northeast forests.

Dr. Tim Fahey
Severe soil freezing occurred in mid-winter, 2006 at HBR. Ironically, a warming climate is likely to result in more soil freezing in northeastern forests because the insulating effect of the mid-winter snowpack may be lost.
Don Buso
Experimental snowpack removal resulted in soil freezing and subsequent high fluxes of nitrate from soils at HBR.
