One of the main points against the CO2 and other greenhouse gases being the cause of global warming was that all the models predict that the troposphere would heat up faster than the air lowere down. The programme stated that this was not what was happening: the air lower down was heating up faster than the troposphere so the greenhouse gases were not warming up the planet.

Although I've always been sceptical of the causes of global warming (in my opinion you can make a mathematical model fit any argument you want it to) I'd much rather live on a planet without man-made pollution whether it causes global warming or not.
