Study: Global drought not linked to climate change

Posted: Updated:
CHICAGO (FOX 32 News) -

That's what research published in the journal Nature states.

Senior Fellows from Australian National University have found that worldwide drought conditions have changed very little since the 1950's.

Previous assessments of global drought have relied on the Palmer Drought Severity Index. But that only accounts for temperatures and does not consider sunlight, humidity or winds.

"There is more than just temperatures, and that's where we went wrong," says researcher Michael Roderick.

Fellow researchers say the new approach addresses a well-known problem with drought measurement in the scientific community. "On average, a warmer world is a wetter world."

Maybe Kevin Costner's version of Waterworld had it right all along!
