Researchers say the biggest and most damaging hurricanes are now three times more frequent than they were 100 years ago.
Using a new method of calculating the destruction, the scientists say the increase in frequency is "unequivocal".
Previous attempts to isolate the impact of climate change on hurricanes have often come up with conflicting results.
But the new study says the increase in damage caused by these big cyclones is linked by global warming.
Hurricanes or tropical cyclones are one of the most destructive natural disasters. The damage inflicted by Hurricane Katrina in 2005 was estimated to be $125bn, roughly 1% of US GDP.
