Nobody doubts gravity, so it doesn't make sense to declare belief or disbelief in gravity to put one's self on a certain side of the gravity issue, because there is no gravity issue. People double global warming, so it makes sense to declare belief or disbelief in global warming to put one's self on a certain side of the global warming issue, since it's actually an issue of contention. It doubly makes sense if you want to alleviate the knee-jerk responses that will dismiss what you're about to say since people seem to respond emotionally rather than logically to such a contentious issue. Prefacing the side you're on in this case is like going up to a guard dog at your friend's house and saying "It's ok buddy, I'm on your side. Don't worry." in a soft non-threatening voice.
