Hurricane Andrew hit Florida in August 1992, and was the last category five hurricane to hit the US. CO2 was just barely over 350 ppm at the time.
It has been almost seven years since a major hurricane hit the US, the longest such period in US history. It has also been seven years since Florida was hit by a hurricane, the longest such period in Florida history.
By contrast, during the year 1886 the US was hit by seven hurricanes, including two major hurricanes. Hansen says that 1886 was one of the coldest years on record.
Well, that just proves 350 is a safe level.

“The severity of Hurricane Andrew can also be blamed by Mount Pinatubo’s climate change.”
