It's Not Your Father's Tundra Anymore

Canadian researchers are using satellite photos to show how climate change is prompting vegetation from southern Canada to creep into the tundra, possibly threatening the northern ecosystem. Areas that were normally occupied by herbs, for example, are becoming occupied by shrubs. The tree line is migrating northward. These changes have implications on wildlife and the people who depend on wildlife in the North.

Geologists' Debate Sparks Debate

The International Geological Congress in Oslo, Norway this month apparently took a break from struggling with science in favor of hosting a reality TV segment on “climate change debate.”

Characterized by RealClimate. org as “a step backwards towards confusion,” and hailed in the denier community as evidence of open-mindedness, the panel included a grab-bag of international “skeptics” including Dr. Henrik Svensmark of the Danish National Space Centre (“even though he's not a geologist, and said that he didn't understand what he was doing on the panel”).
