BS it’s getting warmer.
I’m going to build an ark if it doesn’t quit raining soon.

First of all, I don't believe that "the Earth" has a climate. There are lots of climate zones, and they are changing all the time. They get colder, they get warmer, they get wetter, they get dryer. It probably is true that most places are warmer than they were 200 years ago. It's CERTAINLY true that New Hampshire is warmer than it was 10 000 years ago.
This begs the question, "what does this have to do with mankind, and specifically with "greenhouse gasses"?
The assertion that recent changes (as opposed to all the other changes) are "caused" by humans is deeply unscientific, and anyone who believes that science supports this concept is a scientific illiterate.
The problem this poses with Romney is that his stock-in-trade is convening the "experts" to get "the answer", free of any nasty, political motivations.
In a case like this one, where the "experts" are the problem, he is helpless.
