Global warming will bring stronger storms

Washington - Violent storms and tornadoes may become more common as the earth's climate warms, a study by Nasa scientists showed Thursday.

Researchers at Nasa's Goddard Institute for Space Studies developed what they say is the first climate model able to estimate how the strength of storms changes as the atmosphere warms.

The researchers applied global computer models - which evaluate when weather conditions are likely to lead to storms - to a hypothetical climate five degrees Fahrenheit (two degrees Celsius) warmer than the current climate.

"The model suggests that the most violent severe storms and tornadoes may become more common with warming," the study found. - Sapa-AFP
