Biogeochemical feedbacks between the terrestrial biosphere and the atmosphere could be important in modulating future climate change, according to a review article published online this week in Nature Geoscience.
Biogeochemical cycles, such as the carbon cycle, are strongly affected by climate change and other human activities. Almut Arneth and colleagues provide a first estimate of the warming caused by feedbacks between the biosphere and atmosphere over the twenty-first century. They find that biogeochemical feedbacks will warm the planet and potentially negate the cooling effect resulting from carbon dioxide fertilization of terrestrial ecosystems.
