It is well known that northern ecosystems store a high proportion of the world's soil carbon. Substantial loss of this carbon in response to climate warming may significantly increase the amount of atmospheric carbon dioxide, an important greenhouse gas that has been responsible for climate warming in recent decades. The response of soil carbon to warming also plays important roles in the response of vegetation in Alaska, which has implications for animals in the boreal forest. In this talk, Dr. McGuire will explore the linkages of soil carbon to the goods and services that ecosystems in Alaska provide to society.
