+John Christy Fails to Show that Climate Models Exaggerate CO2-induced Warming

The outline for this post is as follows:
  1. Summary and Objections to the Myth
  2. Elaboration on the Myth
  3. Elaborations on the Objections
  4. Posts Providing Further Information and Analysis
  5. References
If you want the "tl;dr" for this post, then I suggest reading sections 1 and 2. Alternatively, if you are familiar with John Christy's claims on tropospheric temperature trends, then simply skip ahead to section 2.

Each numbered point in section 1 corresponds with a numbered portion of section 3. So there is no need to read this entire post; instead, you can look at section 1 to see which numbered point you find interesting, and then go to the corresponding numbered portion in section 3 for further details.

This is the "+References" version of this post, which means that this post contains my full list of references and citations. If you would like an abbreviated and easier to read version, then please go to the "main version" of this post.

References are cited as follows: "[#]", with "#" corresponding to the reference number given in the References section at the end of this post.




1. Summary and Objections to the Myth



Climate scientists John Christy and Richard McNider published a paper examining warming in the lower atmosphere. They use this analysis to argue that climate models exaggerate [1; 9] a parameter known as climate sensitivity [2 - 7; 21]; this implies that the models over-estimate warming caused by carbon dioxide (CO2) [1]. Christy+McNider's claim that models over-estimate climate sensitivity is the myth I focus on in this blogpost.

+Myth: No Hot Spot Implies Less Global Warming and Support Lukewarmerism

1.  The Myth and Its Flaw



Climate models predict that in moist tropical areas, a region of the lower atmosphere will warm more than Earth's surface. This is known as the "hot spot". The myth states that the lack of a hot spot implies that various factors will not substantially increase global warming to the levels seen in climate models. Thus the lack of a hot spot means that mainstream scientists over-estimate future global warming.

Climate models predict that in moist tropical areas, a region of the lower atmosphere will warm more than Earth's surface. This is known as the "hot spot" [1, pages 14 and 14; 3; 15, page 6; 58]. The myth proposes that John Christy, a climate scientist, thinks that there is no evidence of a hot spot.
