Two scientific studies appearing in Thursday's edition of the journal Nature were the first to directly link warming climate conditions and greenhouse emissions to major flooding and heavy rains.

One study on the Northern Hemisphere showed that the likelihood of extreme precipitation on any day rose about 7 per cent in the last half of the 20th century.

A second study by Myles Allen of the University of Oxford in Britain and his colleagues found that human-caused climate change had nearly doubled the risk of extremely wet weather that caused floods.

Until now, climate scientists have projected that temperature increases would be accompanied by heavy rains, but studies had been unable to lay out such stark connections, the authors of the studies said.

Both studies used new sophisticated computer models that analysed data on climate, temperature and carbon emissions, which are blamed for global warming.

'Climate models have improved a lot since 10 years ago when we basically couldn't say anything about rainfall,' said Gabriele Hegerl, a climate researcher and author of the first study along with her colleagues at the University of Edinburgh.

In that study, data was compared from weather stations in the Northern Hemisphere.

Allen's study focussed on floods in England and Wales during 2000.

'What has been considered a 1-in-100-years event in a stationary climate may actually occur twice as often in the future,' Allen said in a summary of his summary published by Nature online.
