The Union of Concerned Scientists has released a report entitled The Climate Deception Dossiers.
For nearly three decades, many of the world's largest fossil fuel companies have knowingly worked to deceive the public about the realities and risks of climate change.
Their deceptive tactics are now highlighted in this set of seven "deception dossiers"—collections of internal company and trade association documents that have either been leaked to the public, come to light through lawsuits, or been disclosed through Freedom of Information (FOIA) requests.
So now we have some idea of "What fossil fuel companies knew and when they knew it". Full report available here [pdf].

That's better than media reporting on a lot of controversial subjects. For example, in most media coverage of scientific subjects, they'll have on 1 scientist and 1 spokesweasel for the company or industry that the science makes look bad - the spokesweasel need not supply any actual evidence or studies, and is often completely full of it. And that's why a lot of people in the US believe that there's a serious debate on subjects that have been settled science for years (and in some cases over a century).
