Northern Ecosystems are Shaped by Snow
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.

A Multidecadal View of Oceanic Storage of Anthropogenic Carbon
A decline in the ratio of ocean carbon accumulation to atmospheric carbon dioxide growth between 1994-2004 and 2004-2014 suggests a reduction in the sensitivity of the ocean carbon sink.
