The Relationship between Atmospheric Carbon Dioxide Concentration and Global Temperature for the Last 425 Million Years

By Paul Homewood


You may recall the BBC’s Royal Institution Christmas Lecture on, yes you’ve guessed it, climate change. It presented this graph purportedly proving that temperature changes (yellow) followed CO2 changes (white):




As I pointed out at the time, the bits of string were horridly fake and misleading.

Perhaps, instead of treating children like, well children, they might have given them the facts:





This is all highly technical, apart from the last sentence. But the Conclusions do not beat around the bush:


“Atmospheric concentration of CO2 is not correlated with temperature.”

“The absence of correlation proves conclusively the absence of causality

It can’t be any clearer than that.

I think the BBC owes its audience an abject apology for misleading them so seriously. And perhaps next time they should get a proper scientist to host their Christmas Lecture.
