Global warming linked to flooding rains

Scientists studying the tropics have found a strong link between warm periods and an increase in the most extreme downpours, reports said on Friday.

A study by Richard P Allan of the University of Reading, in the United Kingdom, and Brian J Soden at the University of Miami, in the United States, showed a rise in the heaviest tropical rains twice that produced by computer models used to assess how climate change could change rainfall, the New York Times reported.

Experts warned that flooding would hit developing countries hardest, with poor drainage systems grinding cities to a halt.

"Flash flooding can cause damage to settlements and societies. It can contaminate ground water, drinking supplies, with potential health effects," Allan told Reuters.
