The Charney Report Revisited

The Charney Report Revisited

Guest Post by Willis Eschenbach

Over on Twitter, Michael Tobis made the claim that the 1979 Charney report entitled “Carbon Dioxide and Climate: A Scientific Assessment”  was a “triumph of 20th century meteorological science”, in part for predicting “surface warming tending to be concentrated in polar regions”

This got me to thinking and when I think, I think about actual observations. So I went and got the UAH MSU satellite data for the temperatures of the lower troposphere (the part of the atmosphere closest to the surface).

Using that data, I calculated the temperature trends by 1° latitude band for the area that the satellite covers (85 North to 85 South). Here is that result:

Figure 1. Temperature trends 1979 – 2018 by 1° latitude band.
UAH MSU T2LT (lower troposphere) satellite data.

A “triumph of 20th-century meteorological science”?

Hardly … this result is totally unlike what Charney et al. predicted. Not just a little different. Not even in the same ballpark.

My very best regards to everyone on a sunny summer day … going outside now to get some work done.
