No Greener Greenhouse

Trees don't suck as much as hoped. In an paper published in the journal Nature, Swiss scientists challenge the belief held by some that rising levels of atmospheric CO2 will make the Earth a greener greenhouse. The belief that forests act as carbon sinks is a key aspect of the Kyoto protocol. Heavily forested nations such as Canada lobbied hard for the recognition that forest and agricultural land management practices that absorb and store carbon dioxide from the atmosphere contribute significantly towards achieving the Kyoto greenhouse gas (GHG) emissions limitation and reduction targets. These beliefs may be overstated. "Some scientists and politicians cling to the idea that a carbon-dioxide-rich future might favour the greening of planet Earth. It's time to disillusion them," says Christian Körner, one of the scientists who authored the paper.
