As the climate warms, rising sea levels will mean more damage from hurricane storm surge.
What scientists know well, and what's left to learn, about extreme weather and climate change.
The peak of hurricane & tropical storm activity doesn’t usually come until Sept. 10. And, on average, there tend to be significantly more storms after the peak than before it.
Pacific hurricanes form off Mexico and head northwest into wide open ocean, so they don't usually do much damage to the continental U.S.
Data shows hurricanes marked an increase in overall destructive power since 1970, driven by an increase in ocean temperature.
The Power Dissipation Index for hurricanes has been on the rise since 1970, along with sea surface temperatures.
This season was the least active since 1982 and the sixth-quietest since 1950.
The current level of understanding makes it hard to say for certain how climate change will influence Atlantic hurricanes in the future.
