A detailed discussion of how they spent a lot of time engaged in repeating well-worn falsehoods is here
For the confused, the article is talking about the Institute for Economic Affairs IEA, a neoconservative think thank focusing on free market economics, and not the more well known International Energy Agency.
I was actually confused why IKEA was contributing somehow forming a connection between them and large scale logging… until I read your comment and re-read the title.
Ya, I read a lot about disasters so when I first read it added an A and thought it was referring to the International Atomic Energy Agency, (IAEA) which studies and helps clean up after radiation incidents like broken or stolen radioactive medical equipment, reactor excursions, and other such incidents.
After I reread the acronym I was like I could swear the IEA was an energy agency that published a lot of stats on green energy and yet their talking about neoconservative economics?
At least think tanks like The (White) Heritage Foundation have somewhat memorable names and don’t use a legitimate organization’s name.
