Climate Change Endgame In Sight?

From go-to guy Steven Hayward, at Power Line:
In my Weekly Standard cover story about the fallout from the “Climategate” email scandal three years ago, I offered the following question by way of prediction:
Eventually the climate modeling community is going to have to reconsider the central question: Have the models the IPCC uses for its predictions of catastrophic warming overestimated the climate’s sensitivity to greenhouse gases?
The article then went on to survey emerging research (U.S. government funded!) casting doubt on high estimates of climate sensitivity, along with alternative explanations on some climate factors, such as “black carbon.”  The question in my mind the time was how long this would take to begin to break out into the “mainstream” scientific and media world.

That day appears to have arrived.  The new issue of The Economist has a long feature on the declining confidence in the high estimates of climate sensitivity.  That this appears in The Economist is significant, because this august British news organ has been fully on board with climate alarmism for years now.  A Washington-based Economist correspondent admitted to me privately several years ago that the senior editors in London had mandated consistent and regular alarmist climate coverage in its pages.

The problem for the climateers is increasingly dire.  As The Economist shows in its first chart (Figure 1 here), the recent temperature record is now falling distinctly to the very low end of its predicted range and may soon fall out of it, which means the models are wrong, or, at the very least, that there’s something going on that supposedly “settled” science hasn’t been able to settle.  Equally problematic for the theory, one place where the warmth might be hiding—the oceans—is not cooperating with the story line.  Recent data show that ocean warming has noticeably slowed, too, as shown in Figure 2 here.
