The claim that old-growth forests play a significant role in climate mitigation, based upon the argument that even the oldest forests keep sucking CO2 out of the atmosphere, is being refuted by researchers at the University of Copenhagen. The researchers document that this argument is based upon incorrectly analyzed data and that the climate mitigation effect of old and unmanaged forests has been greatly overestimated. Nevertheless, they reassert the importance of old-growth forest for biodiversity.
