"Name-calling (e.g. childish overuse of the word ""troll"" for anyone who urges caution or offers a slightly different POV) is a form of bullying and has no place in this kind of debate.  It is laughable for someone whose first resort is to label a new voice a ""troll"" and then talk about promoting ""ignorant"" POVs.

We live in a fascinating time - we are extrapolating given current facts into future trends that may have grave consequences for us all.  ""Global warming"", though, has come to mean more than specifically just the undoubted heating up of the globe in the last few years.  What is debatable, however, is the future - will it continue?  This is where fact meets theory.  Supoose next year the earth starts to cool again for several decades, then warms again, then cools again. What are we to make of it?  We are trying to make sense of this as we go along, but we cannot call a future event a ""fact"" just yet.  That we have got warmer is a fact.  That we will continue to get warmer is a theory.
