Bernie Lewin has posted another of his must-read climate history pieces, this time looking at the history of claims about detection and attribution of temperature changes to mankind. His point is that claims that "Exxon knew" back in the 1970s are absurd when set in the context of what climate science was saying on the subject of an anthropogenic influence ten, or even twenty years later.
It's beautifully written and confirms Bernie's place as an important historian of global warming science. You must be able to get a very comical juxtaposition by reading Bernie's erudite thoughts after perusing the effusions of a "proper" historian like Naomi Oreskes.
