@Franck R Sorry was my cherry-picking data too global for you. I know I quoted the IPCC but it's reports are novels really. This is how it works: The world's leading climate scientists are given that title by cynical politicians. They do not essentially write the final version of the IPCC report. It is reverse engineered. The Summary for Policymakers is thrashed out by a very large group of politicos at the UN. Line by line. Remember, these are not scientists, but government lackies. Then they go back to information the scientists gave them and change it. The scientific statements must conform to the political ones, not the other way around.
The IPCC was set up to find man-made global warming and when you look for something you find it, and indeed they have on the face of it, but when you look deeper you find a dearth of real evidence.
Take AR5, that says all observed warming (0.66°C) since 1950 is due to combined anthropogenic forcing (Fig. 10.5, IPCC core writing team, page 6). This relies upon modelling, or rather multi-modelling. In fact when you lift the curtain it relies on 15 models (Fig. 10.4, page 882). These models are all over the place. The models' results are not consistent with the assumption that there is a clear connection between GHGs and warming. GISS-EH-2 is particularly 'not well constrained' as the terminology goes. "Scaling factors" then have to be applied so things fit with the HadCRUT dataset. Some of the scaling factors are even negative! Explain why that has to be done!
