(PhysOrg.com) -- In a paper highlighted in Nature Climate Change today, Nigel Arnell, Director of the Walker Institute for Climate System Research at the University of Reading, and colleague Detlef van Vuuren from the Netherlands Environmental Assessment Agency found that stringent measures to reduce greenhouse gas emissions could half the adverse impacts of climate change on water scarcity by 2100, although some models suggest impact reductions as low as 15%. The large range exists because climate models do not agree on exactly how rainfall will change in the future.
