Climate change on Panorama

Last week's Panorama programme on BBC1 was about the science of climate change. Now Panorama is a far more tabloid style programme than was the case when I used to watch it 30 years ago. However, I was interested that the supposedly disagreeing scientists all seemed to beleive that the world is warming. The only people who didn't believe in global warming were members of the public. Small sample size, for sure, but interesting none the less. The controversy amongst the scientists seemed to be the validity of the "hockey stick" global temperature graph.
