If we let climate change run its course, this could be a fairly typical winter 30 or 40 years from now.

We're vulnerable to begin with, and climate change exacerbates the vulnerability.

The hurricanes we are seeing are indeed a direct result of climate change and it's no longer something we'll see in the future, it's happening now.
