Video: Climate Models Used By the IPCC for AR5 Are…

In honor of the IPCC releasing the Summary for Policymakers of their 5th Assessment Report today, I thought I’d present something to you that the IPCC would rather the public and policymakers didn’t know.

My new book Climate Models Fail includes numerous tidbits of information that I have not presented in any blog posts to date.  One of them is included in the following video. The video starts with quick discussions of the global warming plateau, and the additional model failures to properly simulate precipitation and sea ice area—things many of you already know.

Then, after those brief overviews, the video returns to surface temperatures, specifically sea surface temperatures.   I discuss what appears to be a very odd way the climate modelers compensated for their failures to simulate the multidecadal variability of the North Atlantic.  It’s one of those d’oh, slap-your-forehead things.  Have I got your interest yet?

Spoiler Alert:  If you’ve purchased Climate Models Fail already, but haven’t yet reached Section 7, and would rather read this discussion where it’s presented in the book, then don’t watch the following video.

Climate scientists/modelers know very well the rate at which global sea surface temperatures have actually warmed.  What’s discussed in the video and in the book is the only explanation I have for their blatant failure to model anything close to the observed warming rate of global sea surface temperatures over the past 30 years (other than total incompetence on the parts of the modelers).

And what it boils down to is…..…the climate models used by the IPCC for their 5th Assessment Report are crap.  No ifs, ands, or buts.


If you haven’t yet purchased a copy of Climate Models Fail, there are all sorts of goodies in it. What I’ve presented in the video is an example.

    Climate models used by the IPCC are Bullshit!

    – Penn and Teller episodes I’d like to see.

    They already did a global warming episode 🙂 (possibly NSFW)

    Fine video, Bob. Your excellent graphs make it BLATANTLY obvious, indeed, that the IPCC’s climate models are CRAP!. Heh.

    Thanks for sharing the Penn and Teller global warming episode, Beer Holiday. Refreshingly forthright (although, yes, the language was pretty bad in places — I finally had to leave it — the vulgar language underscores the disgusting reality of what the IPCC is and does).

  6. can the Skeptics unite, to speak with one voice; as an official opposition to IPCC?
