Tropical Cyclones and Climate ChangeTropical Cyclones and Climate Change
Intergovernmental Panel on Climate Change (2007):
• As of now, ‘there is no clear trend in the annual numbers of tropical cyclones’.
• Under ongoing global warming, however, ‘it is likely that f t t i l l ill b i t ithfuture tropical cyclones will become more intense, with larger peak wind speeds and more heavy precipitation…’.
