DES MOINES, Iowa (AP) — More than 130 scientists from Iowa colleges and universities say this year's drought is consistent with a warmer climate predicted as part of global climate change and more droughts can be expected.

Scientists and researchers from 27 Iowa colleges and universities signed the Iowa Climate Statement released Monday. It says a warming climate causes wet years to be wetter and dry years to be hotter and dryer. Those extremes lead to more flooding and drought, and Iowa has experienced both in recent years.

The state was hard hit this year when drought spread across two-thirds of the country.

The scientists say warming will continue as global emissions increase and greenhouse gases accumulate, and they expect a growing number of droughts as soon as the 2020s.
