Ok, for a debunking of the (very old) scientific points made in the programme see the excellent Real Climate site - actually written by climate scientists - at:

You will also find the oceanographer Carl Wunsch on that site, claiming that he was "completely misrepresented" in the programme and is considering a formal complaint. The Independent reports on this and the fact that Martin Durkin, the producer of the documentary has long been thoroughly discredited here:

The same Martin Durkin - the man who claims he was just trying to put the other side of the debate - has now emailed a four letter tirade to academics who dared to question the veracity of his programme's claims, as reported by the Times here:

It also turns out that three of the individuals featured in the programme were individuals who are actually no longer working at the universities with which they were captioned, and hence have no academic accountability:

Amusingly enough, I also noticed that at the programme's own website
