There is very high confidence that uncertainties in cloud processes explain much of the spread in modelled climate sensitivity.

I laughed when I read this. It is so disingenuous, it's shameful.

It's taken from the executive summary of the chapter evaluating climate models in the IPCC 5th Assessment Report. I won't start on models honest! but I will say that unlike you and me who would "evaluate models" by subtracting the observed temperature from the calculated temperature at numerous points along the time-axis, they "evaluate models" by comparing them to the models used in the 4th Assessment Report!! I shit you not. Unsurprisingly, they evaluate the new models as being better than the old models. They don't say the new models aren't very good at all.

They don't say no-one knows much about cloud processes. They don't say the models are so poor they disagree badly with each other. NOTE that they do bury these two facts in subordinate clauses within a sentence that extols their very high confidence in such-and-such. Very high confidence is a good thing, right?! Isn't it?! Well when you parse it, the such-and-such is actually a statement of the bleeding obvious. Expressing very high confidence in the bleeding obvious is the height of sophistry.

Everyone involved in the climate hysteria should be thrown in a very large pit.
