The scientists have no ability to profit from Global Warming, to the contrary, since big business and so many politicians want it to be a fairy tale, or at least ignored, anyone saying it exists and has the data to prove it knowingly puts turns themselves into a target.
Those emails, when reviewed in their entirety, show nothing wrong with the data collection and processing, nor with the conclusions of the climatologists. Of course to those who don't understand the specifics, or worse, do understand but wants to hide it, a half assed deception using partial and out of context quotes can easily manipulate many people. This has been proven time and time again, just look at Fox 'News' viewers.
As to any scientific field wide conspiracy, it'll never happen, and by the very nature of the process of peer review and competition to discover or publish, can't happen. Unlike political parties, the largest group of scientists that can work together to pull one over is a single research group. (Size of research groups vary, but are never very large.) No scientific field is comprised of only one group. And because of this, even if a group tried to fake something, the others would find out and blow the whistle. Happens all the time, though most of them I've heard about with fake research or conclusions have been with Chinese and North Korean claims. For that matter, those charlatans were outed by the rest of the world scientists pretty much immediately. The B.S. detectors worked right off the bat, but it took a week or two for the denouncements to get published because it takes time to write them, have enough research backing it up to prove your point, and getting it published. On the other hand, factless B.S., or baseless B.S. can be spewed out as fast as con man, err, Fox News Anchor can read the teleprompter.
Have you ever heard someone say, "Extraordinary claims require extraordinary proof."?
Scientists work, live, and breath that very credo. To violate it is anathema to their entire way of thinking. That's not to say a few don't go nuts for some reason and violate it, but to a scientist that kind of stuff is like a mass murderer. They have to be stopped as quickly as possible, and it's a good thing that such a minuscule percentage of the populace (way less than 1%) ever does such atrocities.
Media Personalities and Politicians rarely if ever follow that credo. They spew lies, misrepresentations, and obfuscations like Niagra Falls does water. So tell me, who are you going to trust on matters of science? Someone that has a vested interest and ethics in being correct, no matter how embarrassing it might be, or someone that could care less about the truth, but wants to manipulate things to gain more power, money, and influence, if not all three.
Also, don't forget, the scientists study their fields for many years. How long do you think politicians, pundits, or other media types study those same fields?
So if you for some reason think the non-scientists know more about a scientific field than it's scientists, then I would suggest that the next time you need surgery, don't dare go to a surgeon, go find an auto-mechanic or airline host and have them do your surgery, after all, by your reasoning, they must know more than the trained expert.
