Nick, I read this

Does this meet your criteria?
Now these guys don't agree with my opinion but, in an effort to rebuff the arguments of skeptics like me, they offer no hard scientific proof to link climate change to man made emissons.
They cannot explain why there was no warming between 1945 and 1976, or how the lower atmosphere isn't warming in sympathy with the surface; they also state that sunspot activity has been exceptional for the last 70 years compare to the last 11,000 yet ignore it as a factor because it doesn't fit in with the 'modelling'.
The best they can come up with is that man made emissions of greenhouse gases are 'Probably' the cause of climate change
- well Carlsberg claim that their lager is Probably the best in the world but it most certainly ain't
