One of the more unfortunate memes that makes an appearance whenever climate science is discussed is the accusation that, by hyping their results, climate scientists are ensuring themselves steady paychecks, and may even be enriching themselves. A Google search for "global warming gravy train" pulls out over 50,000 results (six of them from our forums).
It's tempting to respond with indignation; after all, researchers generally are doing something they love without a focus on compensation. But, more significantly, the accusation simply makes no sense on any level.
You can't make a bundle pushing the consensus
So, are there big bucks to be had in climate science? Since it doesn't have a lot of commercial appeal, most of the people working in the area, and the vast majority of those publishing the scientific literature, work in academic departments or at government agencies. Penn State, home of noted climatologists Richard Alley and Michael Mann, has a strong geosciences department and, conveniently, makes the department's salary information available. It's easy to check, and find that the average tenured professor earned about $120,000 last year, and a new hire a bit less than $70,000.
That's a pretty healthy salary by many standards, but it's hardly a racket. Penn State appears to be on the low end of similar institutions, and is outdone by two other institutions in its own state (based on this report). But, more significantly for the question at hand, we can see that Earth Sciences faculty aren't paid especially well. Sure, they do much better than the Arts faculty, but they're somewhere in the middle of the pack, and get stomped on by professors in the Business and IT departments.
