Deaths and health problems from floods, drought and other U.S. disasters related to climate change cost an estimated $14 billion over the last decade, researchers said on Monday.

"When extreme weather hits, we hear about the property damage and insurance costs," said Kim Knowlton, a senior scientist at Natural Resources Defense Council and a co-author of the study. "The healthcare costs never end up on the tab."

The study in the journal Health Affairs looked at the cost of human suffering and loss of life due to six disasters from 2000-2009.
