Study Finds Unexpected Decadal Decline in Global Evapotranspiration, Links It to Moisture Limitation in Southern Hemisphere

Green Car Congress

Most climate models have suggested that evapotranspiration, which is the movement of water from the land to the atmosphere, would increase with global warming because of increased evaporation of water from the ocean and more precipitation overall. Data indeed show that some areas are wetter than they used to be. Jung et al.
