The problem with all these predictions of the end of the world is simply that we don't have a lot (relatively speaking) of data to build a climate model on. We have around 200 years worth of data, but can only guarentee the accuracy of the last 40 years or so worth of data. So, essentially, we are predicting the actions of a system that has operated for millions of years based on a couple of hundred years of data (160 of which is possibly not accurate).

To me, it seems a bit like predicting the personality of a person you've only just met based on their actions in the first 2 minutes.
