“But the new report says the true figure since 1951 has been only 0.12C per decade – a rate far below even the lowest computer prediction.”

Okay, I am certainly no climatologist but I DO have some small background in precision measurement. I steadfastly refuse to believe that anyone can measure the average annual temperature of the entire Earth with that degree of precision and judging from reports I have seen concerning the location of many temperature measurement stations and the way that certain ones are just thrown out I doubt that they can even come within plus or minus one whole degree per year, let alone .12 degree over an entire decade. At that rate it would take eighty plus years to increase one degree. That has to be signal noise, not measurement.
If anyone cares to educate me on this I am open but otherwise I call BS on the whole thing.
Their level of accuracy is another matter.
You should, on that last. I know a fair amount about thermometry and Thermodynamics, and the fundamental reality is that we have only had satellite temperature measurement to the point where we have anything like a decent world average temperature for a few handfuls of years. I still don’t trust the adjusted earth stations, and going back further, the tree ring nonsense is complete flights of fancy, when it comes to helping get global average temps to a tenth of a degree F.
