'Follow the money' works in a number of cases,

from Globular Warmering True Believer scientists & politicians to just plain corrupt politicians.
What has also almost entirely escaped attention, however, is how Dr Pachauri has established an astonishing worldwide portfolio of business interests with bodies which have been investing billions of dollars in organisations dependent on the IPCC’s policy recommendations.

These outfits include banks, oil and energy companies and investment funds heavily involved in ‘carbon trading’ and ‘sustainable technologies’, which together make up the fastest-growing commodity market in the world, estimated soon to be worth trillions of dollars a year.

The couple accumulated millions in GM holdings in the early 2000s through Debbie Dingell's job, by far the largest portion of the family's personal wealth, public records show. At the same time, John Dingell was Detroit's staunchest ally, fighting against emissions and fuel-economy standards that could have hurt the short-term profitability of automakers.

Kind of like Rep. Barney Frank(Corrupt As You Can Be-Evil Party-MA) sleeping with somebody on the board of Fannie Mae while he was one of the 'regulators' of FM.

Speaking of FM and Freddie Mac, and Frank insisting "I had nothing to do with the problem!", when was it starting?

"New research by Edward Pinto, a former chief credit officer for Fannie Mae and a housing expert, has found that from the time Fannie and Freddie began buying risky loans as early as 1993, they routinely misrepresented the mortgages they were acquiring, reporting them as prime when they had characteristics that made them clearly subprime or Alt-A. [Emphasis added]

"[A]s early as 1993." Hmm. Doesn't that put this alleged routine misrepresentation well before Designated Fall Guy Franklin Raines' tenure as head of Fannie Mae--and back into the watch of Getting-Away-With-It-Because-I'm-Well-Connected-and-Spread-It-Around Mondale campaign manager and initial Obama veep-vetter Jim Johnson? I think it does! (Johnson was CEO of Fannie Mae from 1991-1998.) ... P.S.: 'Misrepresented the mortgages ...." Isn't misrepresenation some kind of, I dunno ... fraud or ... crime?
Why, yes, it is! And lets' see, 1993... wasn't Bill Clinton President then? And for the next eight years? But Bush & Co. are responsible for all this, huh?

Yeah.

Right.
