Indian monsoons may fail more often due to climate change: Study

OSLO (REUTERS) - The Indian monsoon is likely to fail more often in the next 200 years threatening food supplies, unless governments agree how to limit climate change, a study showed on Tuesday.

The monsoon rains could collapse about every fifth year between 2150 and 2200 with continued global warming, blamed mainly on human burning of fossil fuels, and related shifts in tropical air flows, it said.

"Monsoon failure becomes much more frequent" as temperatures rise, Dr Anders Levermann, a professor of dynamics of the climate system and one of the authors at the Potsdam Institute for Climate Impact Research, told Reuters.

India's monsoon, which lasts from June to September, is vital for India's 1.2 billion people to grow crops such as rice, wheat and corn. India last faced a severe widespread drought in 2009 and had to import sugar, pushing global prices to 30-year highs.
