Yes.
The deserts will expand. Then they will recede.
It will get warmer. Then it will get colder.
It will get drier. Then it will get wetter.
Its called weather.
So what?
Think of all the tundra that will be warm and toasty after this process is complete! I personally can't wait to go golfing in the 70 degree weather near the north pole!
