The chemistry Ph.D., but it's worse than that--it would be unusual to be hired as a professor without putting in several years as a post-doc. They would probably make less than what they would have made in private industry with a B.S.

EDIT for Dr Jello: Which "party schools" are you talking about, Caltech? Stanford? MIT? Oxford? Princeton?

Seeing that schools that teach so-called "global warming" are typically party schools, and oil firms hire the cream of the crop from top Universities, clearly the right answer is Chem PhD's working for the oil industries. Plus they actually produce products that people can use.

most very likely the pawn for Big Oil

here's one:

Robert Carter: -In 2012, documents acquired from The Heartland Institute revealed that Carter was paid a monthly fee of $1,667 (USD), "as part of a program to pay 'high-profile individuals who regularly and publicly counter the alarmist [anthropogenic global warming] message'." While Carter did not deny that the payments took place, he declined to discuss the payments. Carter has denied that his scientific opinion on climate change can be bought.

The title doesn't matter much when it comes to negotiation. It's how they present themselves based on experience, skills, and other qualifications. But to give you an idea based on the usual pay for such jobs, see http://bitly.com/16MVx97 and http://bitly.com/Y115CQ .

does money under the table from big oil count?

The oil shill of course. Lies are funded by private sector money which doesn't have to be accounted for
