Not the IPCC (“NIPCC”) Report

If you’re growing impatient for model-bashing, no fear; there’s a whole chapter for you (Chapter 4: “Climate Models are Not Reliable”), which offers up the usual mix of straw man descriptions of how climate models actually work, and red herrings about supposedly missing feedbacks and processes. Fortunately, RealClimate wiki provides some one-stop rebuttal shopping.

The falsely-titled chapter 5 (“The Rate of Sea-Level Rise is Unlikely To Increase”) rests upon incorrect claims that sea level rise projections are exaggerated, and or that the IPCC supposedly lowered their projections of future sea level rise. Chapter 6 (“Do Anthropogenic Greenhouse Gases Heat the Oceans?”), if we take it literally, asks a rather embarrassing question (‘No grasshopper! The greenhouse gases are ‘gases’. They heat the atmosphere and surface and a warmer atmosphere transfers some of that heat to the ocean below. You still have much to learn.’). Chapter 7 (“How Much Do We Know About Carbon Dioxide in the Atmosphere?”) answers the question it asks with the usual nonsense about how the increase in CO2 is probably natural, or that we can’t trust the CO2 record, and that CO2 isn’t rising as quickly as projected anyhow. And chapters 8 and 9 offer the requisite disclaimer for contrarians that, even after you’ve debunked everything they’ve said so far, and come to the inescapable conclusion that anthropogenic climate change is (1) real, and that (2) future changes will be profound if we continue with business as usual, ‘it will be good for us anyway’..

In concluding, We’d like to level with our readers. Some of us thought that the “NIPCC” report was so self-evidently nonsense that we shouldn’t even give it the benefit of any publicity. But it does give a great opportunity to give the RealClimate ‘wiki’ a test ride. We hope to expand this resource in the future, and we’d actually welcome some additional outside help. (In fact, much of it is already due to some dedicated volunteers. Thanks!). So if you have a desire and the time to help organise this effort, drop us a line and we’ll set you up.

    Mike, photons carry energy whether they’re infrared, visible, ultraviolet. When a photon is absorbed by a molecule — earth or water, mostly — that energy changes form, causing the molecule to vibrate in many different ways. A vibrating molecule with others near it bangs on nearby molecules, making those vibrate and move. “Brownian motion” is those molecules banging on one another, and you can see that in a microscope or video. In a solid or dense gas or liquid the energy averages out _really_fast_ (and the average of that energy is the temperature we notice). Some of those vibrating molecules emit photons too — at the temperature of the surface of the planet.

    That’s how solar energy becomes warmth on Earth.

    I should have just given you a pointer to a better explanation instead of trying to retype one from memory, this is the “long answer because I didn’t have time to give you a brief answer” problem with blogs; perhaps someone else will do that.
