A new study indicates that the world will experience more frequent and more extreme drought and aridity than currently experienced in the coming century, exacerbated by both climate change and land-atmosphere processes. The researchers demonstrate that concurrent soil drought and atmospheric aridity are largely driven by a series of land-atmosphere processes and feedback loops. They also found that land-atmosphere feedbacks would further intensify concurrent soil drought and atmospheric aridity in a warmer climate.
