Tracking the scent of warming tundra
(PHYSorg.com Biology)

Climate change is causing subarctic tundra to warm twice as fast as the global average, and this warming is speeding up the activity of the plant life. Researchers from the University of Copenhagen, Denmark, and the Helmholtz Zentrum München, Germany, have now elucidated how this warming affects the tundra ecosystem and the origin of an increased amount of volatile compounds released from the tundra.
