I haven’t posted much lately because I’ve been hard at work on my new book. It’s titled Understanding Statistics, and I expect to finish in a week or two. I’ll be sure to post here when I do, hoping that lots of you will buy it. Even if you don’t need one for yourself, you might know somebody who would enjoy and make good use of it. Who knows, maybe 20 of you will send a copy to Anthony Watts. Maybe he would learn something from it. Irony of the richest kind.
Clearly, David Whitehouse has enough rope. To hang himself.
The WUWT blog has a post by David Whitehouse (of the “Global Warming Policy Foundation”) discussing global temperature data. It features this graph from the leaked copy of the not-yet-completed 5th assessment report (AR5) of the IPCC (Intergovernmental Panel on Climate Change):
Two fake skeptics of global warming, Willie Soon and Nils-Axel Morner, have written a commentary in the Washington Times about sea level rise in which they use the most shoddy “science” imaginable to claim that sea level rise data is based on shoddy science.
November marks the end of the “climatological” year, which extends from Dec. through Nov. rather than Jan. through Dec. as the calendar year. Since NASA GISS has updated their global temperature estimate through November, we can compute the global average annual temperature for the climatological year.
And here it is (animated GIF, you may have to click the graph to see the animation):
A new paper by Rahmstorf et al. compares observed climate changes, specifically global temperature and sea level rise, to projections from IPCC reports. The result: temperature is rising in outstanding agreement with IPCC projections, while sea level is rising faster than expected.
