Snow Is Good by Dr. Peter Groffman. Most people pay attention to climate change in the summer, when faced with heat waves, hurricanes, and severe thunderstorms. In the northeast, climate warming is actually more marked in the winter, and the loss of snow cover can have a ripple effect on tree growth and groundwater recharge. Cary Institute scientist Dr. Peter Groffman will discuss how mild winters threaten soil productivity, plant growth, and freshwater resources. Admission free.
