John Christy and Atmospheric Temperature Trends

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


John Christy is a climate scientist, with a particular focus in atmospheric temperature trends. Some sources present Christy as being an intellectually serious "skeptic" of carbon-dioxide-induced (CO2-induced), man-made climate change [7; 26 - 31]. Yet Christy has repeatedly misled Congress and the public. Christy's most egregiously misleading statements include:

+John Christy, Climate Models, and Long-term Tropospheric Warming

The outline for this post is as follows:

1. Introduction
2. Summary of the Objections
3. Elaboration on the Objections
4. 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 2 corresponds with a numbered portion of section 3. So there is no need to read this entire post; instead, you can see which numbered point you find interesting in section 2, and then for further details you can skip to the corresponding numbered portion in section 3.

Beginning of a new series

In the upcoming weeks, I'll be making a series of posts on climate science. Before I start, I want to state this upfront:

I have no expertise in climate science, so you're not getting an expert's opinion here (my expertise is in immunology, and to a lesser extent, philosophy). Instead, my goal is to cite reputable sources of scientific information in order to address some common public misconceptions about climate science. I'll also throw in some of my own views, based on the scientific research I read.

Hope people find this series helpful.
