Crock of the week – CO2 lags behind temperature


Finally, Peter Sinclair nails probably the most deceptive and cynical piece of deliberately misleading BS that the professional denier/inactivist/sceptics use to fool the gullible.

It’s the argument based on the Vostok ice core records that clearly show that (in most cases) when the climate changed naturally, in the past, first the temperature started rising then, about 800 years later, the atmospheric CO2 levels went up.

The deniers ruthlessly use this cherry-picked piece of evidence along these lines – they claim that as CO2 always lagged temperature rise in the past, then the observed increase in CO2 we are seeing since the start of the industrial revolution must have been caused by a natural temperature change cycle that started before that and that the global warming we are measuring (that even the deniers no longer deny is happening) is just a continuation of this natural cycle. S. Fred Singer is probably the worst denier in this regard because he publishes books about it and other denier classic canards.

This “CO2 lags temperature” argument was ruthlessly misrepresented in “The Great Global Warming Swindle” by carefully deceptive editing – the scientist who was exploited by the producer has completely disavowed what the programme made him appear to say!
