Global warming 'to bring torrential rain and flooding' Scientists say torrential rain and flooding may be the most serious consequence of global warming for millions of people in the southern hemisphere over the next 100 years. A new study shows that the Asian southwest monsoon has become more intense during the last four centuries, probably as a result of warming in northern latitudes. The findings suggest it will continue to strengthen during the coming century as man-made greenhouse gases force up temperatures in the north. About 65% of the world's population live in monsoon regions and are highly vulnerable to changes in the weather. Too little rain during weak monsoons can lead to crop failures while strong monsoon downpours can cause flooding, crop damage, and population displacement. Scientists in the United States and India based their findings on fossils of microscopic sea creatures. Winds blowing along the coast of the Arabian Sea during monsoons cause an upwelling of water which increases the abundance of the animals. The stronger the monsoon, the greater the numbers of the organisms. Sea sediment cores containing the fossils from along the coast of Oman provided a unique record of monsoons dating back more than 1,000 years. Writing in the journal Science, the researchers said the evidence showed the monsoon had intensified over the past four centuries as the northern hemisphere warmed. Chief researcher David Anderson, of the Institute of Arctic and Alpine Research at the University of Colorado, Boulder, said there was an apparent link between Eurasian snow cover and increasing monsoon strength.
