Using ensemble hydrological simulations, an international team of researchers (USA – Michigan State University, Japan, Austria, Germany, UK, Greece, Switzerland, China, Belgium, the Netherlands) shows that climate change could reduce TWS (Terrestrial water storage ) in many regions, especially those in the Southern Hemisphere. Strong inter-ensemble agreement indicates high confidence in the projected changes that are driven primarily by climate forcing rather than land and water management activities. Declines in TWS translate to increases in future droughts. By the late twenty-first century, the global land area and population in extreme-to-exceptional TWS drought could more than double, each increasing from 3% during 1976–2005 to 7% and 8%, respectively. Their findings highlight the importance of climate change mitigation to avoid adverse TWS impacts and increased droughts, and the need for improved water resource management and adaptation…read more.
