Environment: Intense rainfall due to global warming could raise flood riskClimate scientists have issued a fresh warning over the future risk of flooding after research showed heavy rainstorms are likely to become even more intense than predicted.Rainfall is expected to increase with global warming global warming, the gradual increase of the temperature of the earth's lower atmosphere as a result of the increase in greenhouse gases since the Industrial Revolution. because the atmosphere can hold more water as it heats up, but the extent to which rainfall patterns will change in the future has been unclear. Writing in the US journal Science, researchers warn regions that are already vulnerable to flooding will be hit hardest by rainstorms in the future, and that previous predictions may have underestimated how intense these rainstorms will be. Researchers from Reading and Miami Universities Miami University, main campus at Oxford, Ohio; coeducational; state supported; chartered 1809, opened 1824. The library has extensive collections in literature and American history, including the William Holmes McGuffey Library and Museum and the Edgar W. used satellite data from 1987 to 2004 to see how natural changes in surface and air temperatures caused by El Niño weather events influenced rainfall over the tropics tropics, also called tropical zone or torrid zone, all the land and water of the earth situated between the Tropic of Cancer at lat. 23 1-2°N and the Tropic of Capricorn at lat. 23 1-2°S. . They found a clear link, with countries experiencing far more rainfall as temperatures rose. "When we first looked, we saw that the warm periods were associated with the periods of heaviest rainfall, but when we looked more carefully, we found the models underestimated what the satellite data showed by a factor of two to three," said Richard Allan Richard Allan (born 11 February 1966) was the Liberal Democrats Member of Parliament for Sheffield Hallam from the general election of Thursday the 2 May 1997 until the dissolution of Parliament on 11 April 2005. , who led the study. If other researchers are able to confirm the findings, it suggests areas already prone to flooding may experience far more problems as global temperatures rise.
