The UK's HadCRUT3 global temperature dataset has been the IPCC's gold-standard for its political-agenda "science" reports - unfortunately for the IPCC, the HadCRUT dataset also confirms the disappearance of global warming, replaced by a very slight cooling trend

Further, it was estimated by the consensus "experts" that a large increase in human emissions over the last 15 years would bring the world hellish warming. It has not happened.
The climate scientists and their associated climate agencies were immensely wrong, as the adjacent chart indicates.
As can be seen, over the first 15-period, prior to 1998, there was a strong warming trend (+1.4 degrees per century). As a result, the experts said human CO2 was the cause. They then emphatically predicted that this warming trend would continue and even accelerate. But it didn't - instead it decelerated.
As the chart depicts, the last 15 years ending 2012 has seen a very slight decline in temperatures, wiping out the strong positive warming trend completely. This small cooling trend in surface temperatures is also supported by the satellite observations of the atmosphere. The global warming was wiped out even though total human CO2 emmisions were a third larger - 110 billion tons more than prior 15-year span.
In the meantime, they debate amongst themselves about how befuddled they are concerning the lack of warming, obviously confirming what skeptics knew all the time - their bizarre anti-CO2 phobia and rigid consensus constraints have long blinded them to scientific truth.
