To expand a bit on my previous comment, the sad part is that even though we know that the topic is not really controversial scientifically, we somehow, subconsciously, refer to it as one.
Yea the true controversy isn't weather the climate is changing but rather the rate at which it is occurring and the degree to which humans should intervene to take corrective action.
All something needs to be controversial is for there to be a great deal of public disagreement about it. Climate change definitely qualifies. Unfortunately, this has just about nothing to do with factual basis, evidence, etc.
