I accept that climate change is happening. I don't use the term "believe in climate change" because that implies that their is some uncertainty about the issue.
Thank you for posting the link to this essay, it was a pretty interesting read. I did note that all the points were refuted by people with more credibility and lucidity than me in the comments section of the article, and that it should not be confused with a peer reviewed article due to its broad scope and limited depth.
My only contribution would be to note that both of the authors of the essay François-Marie Bréon(who is erroneously listed as director for research CNRS) and Jean Poitou published this out of IPSL lab in france. Sounds really smart heh? bbuuuttt, IPSL doesnt have a physical lab in France. They list two contact addresses at prestigious french universities, but the neither university had heard of them when I emailed them. Bon!
Also, if you go through the IPSL site they don't actually do anything. They don't have any published papers or research. Compare their site to CNRS and see what I mean.
Also, if you try to phone them there is no answer.
I wouldn't claim that IPSL was a vehicle designed to lend credibility to an otherwise unremarkable essay.
I just know what else it could be for.
Also, I couldn't find an original untranslated version of the essay. Both of the co-authors are French, and it written in France. Usually scientific papers are written in your native tongue, and then translated.
Just my 2C
