Climate change: Hurricanes more and more powerful

A new computer modeling work, led by Thomas Knutson of Princeton University (New Jersey), links global warming with the intensity of future hurricanes. Of course, this study is not the first to predict this kind of consequence in case of increase of greenhouse gases in the atmosphere.

Nevertheless, these latest results, published in the Journal of Climate, are based on different models of climate change developed in laboratories around the world. And whatever the theories adopted, the 1300 simulations revealed the same underlying trend: more and more powerful hurricanes. In 2080, the warmer oceans will thus generate climatic phenomena that have never been recorded before, with strong winds and heavy rainfall. Although the risks of particularly destructive tropical storms are higher, the data can not predict if their frequency will increase or decrease, because many parameters are involved. It will be some time before climatologists lead to more accurate forecasts.
