New research shows that wild swings from severe drought to heavy rains are becoming more common with climate change in many parts of the world and that feedback loops from the land itself are likely contributing to the trend. The research looked at four decades of meteorological and hydrological data on a global level and found seven regional hotspots around the world where the trend was getting worse: eastern North America, Europe, East Asia, Southeast Asia, southern Australia, southern Africa, and southern South America.
