I'll have to dig back through my paper notebooks going back over about 20 years. (My ex-wife was a virtue signaler, and I had started to be sceptical. I used a university library, but I don't live near a university any more.)

But I doubt very much the conclusions have changed, especially given the world's dependence on Chinese manufacturing and China's dependence on coal.
