Your correspondent is now a climate commentator. Self-identifying is accepted methodology. 

If you were even half sensible you would stop reading now to go and read Numbers Don’t Lie: 71 Things You Need to Know About the World (2020) by Distinguished Professor Emeritus Vaclav Smil. He has done the maths. 

I don’t know anything about the climate but that never stopped anyone. In the strict academic sense of the word, this article is bullshit.
