Tree death worldwide linked to warming climate
Trees dying at alarming rates is no small concern: trees absorb one-third of human carbon dioxide emissions, and they release this greenhouse gas at death. Our scientists study why and where trees are dying and how their death is caused by a changing climate—and vice versa.
Using the first globally comprehensive data set and our global monitoring system, we predict losses of many forests worldwide by 2100 and discovered wildfires caused by climate change add to the global-warming problem in a dangerous cycle.
