Which Forests Are The Best Carbon Sinks? New Study Says Old Growth Deserves A New Look

Contrary to the national "carbon budgets" as outlined in the Kyoto Protocol, a new analysis in Nature suggests that old growth forests are "carbon sinks" and they continue to absorb carbon dioxide from the atmosphere and mitigate climate change for centuries. Old growth forests around the world are not protected by international treaties and have been considered of no significance in the Kyoto Protocol. That perspective was largely based on findings of a single study from the late 1960s and these scientists now say it needs to be changed. An analysis of 519 different plot studies found that about 15 percent of the forest land in the Northern Hemisphere is unmanaged primary forests with large amounts of old growth, and that rather than being irrelevant to the Earth's carbon budget, they may account for as much as 10 percent of the global net uptake of carbon dioxide.
