Fields of study of IPCC authors



Curious about the people who were telling us to change our way of life because of a changing climate, I decided to research one qualification of the authors of one of the most recent IPCC reports. The qualification I chose was the fields in which they were educated.

It seemed odd that the most prevalent field of study among the group was economics.

A fair number included physics degrees in their biographies.

A few studied philosophy.

I did find one person who had been schooled as a meteorologist. and one with a PhD in climate science. The next most relative was PhD in atmospheric chemistry.  It seemed odd to me that these were all listed as draft contributing authors.

There were none that I could find other than that one who had the word climate any place in their education histories. There were no degrees in geology, climatology, paleoclimatology, atmospheric dynamics, solar physics, historical climatology  or geophysics.

Granted, they are a very scholarly and well published group that are deserving of a lot of respect, but why are there not a lot of actual climate scientists amongst the lot. Could it be that most of those who have actually studied in the field are not convinced of the dangers of a warming climate.

There is no doubt that these are very intelligent and well educated people and that their opinions are valuable, but when it come down to it, they seem to be commenting outside of their expertise. In the end it is only their opinion and perhaps not an adequate base for spending trillions of dollars of tax payer money or making massive disruptive changes to global society.

In Wikipedia there is published a list of scientists, each with credentials in one or more climate science disciplines. I am certain it is not complete, and many bona fide climate scientists are likely omitted. What is notable is that, not a single one is on the list of authors posted here. Nor is a single one of the authors on the wiki list.

What follows is a list of the authors with their individual education histories. It is not 100% complete but is as close as I could get with a couple of days research. This information is not guaranteed as to accuracy and I apologize if I got the wrong person when searching or if I have made other errors. Most of the list is copy and paste, so there may be other errors for which I am not responsible. I encourage anyone who cares to, to do their own research or to expand on mine.
