The comment you were replying to was talking about funding. If you could develop a scientifically plausible model to defend the "burning fossil fuels is not so bad, actually" thesis, your funders would include the oil companies and the greater petrochemical industry. There is a lot more money to fund projects there than... anywhere else in the world, really, by a wide margin.

well oil companies funded "lead fuels are safe" research...

...and it really did backfire (in public relations, politics, etc)

now... I don't think they can actually fund 'research-for-their-profit' -- I mean, would you believe "petro is good for earth" research coming from oil companies, even after the 'lead is good or neutral' research?
