BERLIN (AP) -- Scientists say millions more people around the world are threatened by river floods in coming decades due to climate change.
Researchers in Germany say greater flood defenses are particularly needed in the United States, parts of India and Africa, Indonesia and Central Europe.
River floods are already one of the most widespread and damaging forms of natural disasters around the world.
Using computer simulations, scientists at the Potsdam Institute for Climate Impact Research say the number of people affected by the worst 10 percent of river flooding will increase by up to 156 million in Asia alone by 2040.
The study published Thursday in the journal Science Advances concludes that flood risks will rise regardless of efforts to curb climate change because of greenhouse gases already emitted in past decades.
