Tropical cyclones are fairly random animals, and they respond to the random nature of the atmosphere at any given time, but certainly, this steady warming of the ocean that's been happening in the Atlantic because of the combination of greenhouse gas increases and the particulate pollution decreases, that has a profound effect — and the changes to the particulate pollution have a much more dramatic effect on the hurricanes.

Aerosol decrease may lead to good health, but on the other hand, hurricane risk increases. This is where good things accompany bad things. It's kind of like pros and cons. tropical cyclones are fairly random animals, and they respond to the random nature of the atmosphere at any given time.

There's evidence that tropical cyclones are more likely to stall.

Simply put, warmer air holds more water vapor.
