The Great Global Warming Swindle
Clive:
Absolutely nothing at all Simon. Temperatures were much higher in medieval times than they are now which is why they were able to grow exotic fruits in the UK. It showed that raised carbon dioxide levels follow warm periods not the other way around! Most CO2 emanates from volcanos and the sea. Man only accounts for 0.5% of CO2 production in the world today.

All claim it to be caused by the Sun or volcanos.

That isn't true, you have met me. I'm pretty sure though that you will find lots of scientists who believe that global warming is actually a non-man made effect but it is being accelerated by mankind. I personally feel that the variability of the Sun arguement is fair but I see no evidence for it being much more intense over the last 20 years or so... plus the fact that C02 has risen in the same period dramatically would really make me suspect. Anyway I didn't see the tv show so can't comment more. I always take what I see on the mass media with a huge pinch of salt. The BBC are not biased at all are they...

yes but clive, the C02 levels were not a huge as they are now. If you look back at the ice core samples we currently have the highest C02 levels on record. I'm not sure I believe the arguement of us only produce 0.5% of the C02 and even if that is the case.. how much of the world's C02 absorbers have we destroyed over the last century?

The BBC may be biased towards promoting the idea of man casuing global warming Sam but this programme was made by C4 and their documentaries are usually accurate and well made.
Clive:
Sam I think you really need to see that programme so that you can evaluate it for yourself. All producers have their own agenda when they set out to make a TV programme but there were some real scientific heavyweights from all disciplines featured in The Great Global Warming Swindle. I honestly haven't heard any astronomer or geologist supporting the idea that global warming is man made. Did you mention it in your talk last year? No! I rest my case!! :wahh:
