Climate Change Is Intensifying the Water Cycle, New IPCC Report Finds

Circle of Blue

This trend will continue as glacial melting, decreased rainfall, and a “thirstier” atmosphere jeopardize sources of freshwater in some parts of the globe. The Intergovernmental Panel on Climate Change, a group of the world’s leading climate scientists, released its sixth climate assessment on Monday.
