Northern Ecosystems are Shaped by Snow

by David S. Schimel 12 September 202313 September 2023

Changing climate in the Arctic leads to a shorter snow season but deeper snow in the depths of winter. Under the insulating snow, biological processes are accelerated leading to higher nutrient availability and carbon losses.
