Drought impacts

Background Droughts have major impacts on fluxes between land and the atmosphere, agricultural production, and the carbon cycle. Future projections of drought magnitude and frequencies are surprisingly divergent and interpretations of trends from Earth System Model outputs have drawn conflicting pictures of drought impact trends in a heating climate.

Background There is a current scientific debate if the intensity of the recent 2003, 2015, and 2018 droughts is exceptional in the context of the last millennium. Based on tree-ring reconstructions, some authors find them to be within the range of natural variability (Ionita et al.

Summary Terrestrial primary productivity and carbon cycle impacts of droughts are commonly quantified using vapour pressure deficit …
