Heavy rains not just in the US: current Monsoon in South Asia

08/31/2017 - Devastating rainfall is being observed not just in Texas, USA, but also due to the Monsoon in South Asia. On this issue, the Potsdam Institute for Climate Impact Research issued a statement by Anders Levermann from the Potsdam Institute for Climate Impact Research, Professor at the University of Potsdam and Adjunct Scientist at Columbia University's LDEO, New York:
Heavy rains not just in the US: current Monsoon in South Asia

"Tropical storm Harvey in the US brings terrible rains - and so does the current Monsoon in South Asia. Reportedly, many million people are displaced and more than a thousand died from floods in certain parts of India, Nepal, Bangladesh. This shouldn't be overlooked. Monsoon dynamics are complex, but the science shows that its variability is likely to increase with climate change. Monsoon rainfall will become more extreme if greenhouse-gas emissions are not reduced. Just like with the US storm, a warmer atmosphere can take up more moisture which then can be released in torrential rains. Climate computer simulations have predicted this and now get sadly confirmed by the observed devastating monsoon rains."
