Global Warming In The Tundra

But in the tundra, the vast treeless region in the Far North. As permafrost thaws it releases carbon dioxide and methane, which in turn contributes to global.

However, warming decreased the carbon sink in lightly grazed tundra, but had no effect in heavily grazed tundra. Thus, tundra with a long history of intensive grazing showed a weak response to climate warming.
