Climate change could revive medieval megadroughts in US Southwest

A new study provides the first comprehensive theory for why there were clusters of megadroughts in the American Southwest during Medieval times. The authors found that ocean temperature conditions plus high radiative forcing -- when Earth absorbs more sunlight than it radiates back into space -- play important roles in triggering megadroughts. The study suggests an increasing risk of future megadroughts in the American Southwest due to climate change.
