Anthony Watts published an illustration and an excerpt of the draft of the IPCC’s Summary for Policymakers due out later this month. See the WUWT post Excerpts from the Leaked Summary for Policy Makers. Included with his post is the IPCC’s Figure SPM.1. See my reduced size copy in Figure 1. Based on the numbering, that’s the first illustration policymakers and the public will see when they open the IPCC’s Summary for Policymakers.
That lead-off illustration is obviously one of the IPCC’s focal points. It includes:
- in the top graph of cell a, annual surface temperature anomalies from 3 suppliers (who all rely on the same source data, so it’s overkill) from 1850 to 2012;
- in the bottom graph of cell a, decadal surface temperatures from the same suppliers for the same time period; and
- in cell b, a surface temperature trend map on a Robinson projection, in which the contour levels have been tweaked so that it appears the Earth is ready to burst into flames.
(Original from WUWT post is here.)
The IPCC then goes into a detailed discussion of the warming of global surface temperatures.
With all of the discussions of the recent hiatus period, this is what the public and policymakers will take away from their discussion:
Blah, blah blah.
And this is what the public and policymakers will concentrate on and understand from Figure SPM.1. (See my Figure 2)
STATUS OF MY BOOK CLIMATE MODELS FAIL
I’ve redone about 40 graphs from scratch and completely rewritten 2 of 10 sections—all at the recommendation of the (non-technical) person doing the proofreading. And I’m more than halfway done incorporating the other recommended changes to the text, which make it much easier to read. (I’m having to tone down the language of the person doing the proofreading—she is becoming more and more critical of climate models being used by the IPCC as she progresses through the book and sees how poorly they simulate sea ice, precipitation and surface temperatures.) All in all, I believe Climate Models Fail will be published and available in pdf and Amazon Kindle formats before the IPCC releases their SPM for AR5.
