Ignoring and ‘explaining’ the pause in global warming

While the climate cult continues the drumbeat of doom, they still cannot explain why global warming has “paused”

Back in their glory days of  2007 the United Nation’s International Panel on Climate Change (IPCC) released their fourth assessment report on global warming. Here is what they had to say about the short-term outlook on global temperatures:
For the next two decades, a warming of about 0.2°C per decade is projected for a range of SRES emission scenarios. Even if the concentrations of all greenhouse gases and aerosols had been kept constant at year 2000 levels, a further warming of about 0.1°C per decade would be expected. {10.3, 10.7} …
So the IPCC unequivocally claimed that their models, regardless of which CO2 scenario used, projected that temperatures would rise at a 0.2 C pace for the next two decades. To put that in perspective according to the IPCC the actual per decade increase in global temperatures for the period 1970-1998 was .17 C. This means that the IPCC was projecting an accelerating increase in global temperatures of .03 degrees for the next two decades beyond what it had been the previous two decades.
That was their projection. They even went so far as to maintain that there was already so much CO2 in the climate system that just maintaining it at 2000 levels would still result in a 0.1 C per decade increase. Which is telling yet irrelevant since they also knew  that CO2 was not being maintained at 2000 levels. At the time of the IPCC’s 2007 report atmospheric CO2 levels had increased from 369.14 ppm in January of 2000 to 382.49 by January of 2007.
How do you square that official projection with this statement by Kevin Trenberth a lead author of that report who in 2009 wrote,  “The fact is that we cannot account for the lack of warming at the moment and it’s a travesty that we can’t.” Trenberth was not talking about a one or two-year blip in the global warming narrative, he was talking about what was then over a decade long slowdown in global warming and which now has reached a 17 year “hiatus.”
It is obvious that the “scientists” who for decades were promoting the theory of man-made global warming knew that it wasn’t (warming) while they promoted the idea that it was. At least not anywhere near the “catastrophic” levels they want us to believe.
Between 1998 and 2012 global temperatures  increased at a per decade rate of 0.04 C  or one fifth of the IPCC projection (-.16 C) and decelerated from earlier warming by 0.13 C. So not only did the globe not warm as the IPCC predicted it would, it has not even kept pace with the previous warming, by a long shot.
In 2013 as it became increasingly obvious that global warming was not indeed happening and the scientific branch of the climate cult frantically began to make excuses for their failed projections and some in the cult were feeling, well misled.
David Shukman, Science editor at the BBC and a lifelong member of the cult who for years vociferously and without hesitation had promoted the idea that man’s emissions of carbon dioxide were a harm to the planet wrote the following (emphasis added):
On top of that, the scientists say, pauses in warming were always to be expected.
This is new – at least to me. It is common sense that climate change would not happen in a neat, linear way but instead in fits and starts.
But I’ve never heard leading researchers mention the possibility before.
But our jilted cultist went even further. Not only did he complain about this lack of “transparency” by his fellow members of the cult he actually hinted at the possibility that the foundation for their well crafted belief structure might be flawed.
But what about another possibility – that the calculations are wrong?
What if the climate models – which are the very basis for all discussions of what to do about global warming – exaggerate the sensitivity of the climate to rising carbon dioxide?
Leading up to the great admission that global warming had paue, nowhere in all the released studies or countless press releases had there been any mention of a “pause” or future pause in global warming. All the charts released showed a linear rise in temperatures corresponding to increased CO2 emissions....
