They aren't "fudging" numbers. This is climate data, it's HARD to deal with. You're talking about millions, even billions of measurements over periods of centuries. There are more moving parts to this data than you can possible conceive of.
Indeed, and this is a problem when science tangles up with politics. Here we ware saying it's hard to deal with and requires quite a lot of corrections and processing, while the left of politics runs a coercive campaign that you should be called a pariah if you are not convinced by our data and therefore their policies. In science, our credibility is dragged under far more by agreeing politicians trying to co-opt us than by political opponents disagreeing with us. (Disagreement is part of the process; but being dragged into a sharp tongued campaign about why you must vote for higher taxes on big business or otherwise you're a horrible person is not a part of science, and makes us look like a bunch of corrupt fudgers trying to raise our grant funding by cosying up to the left). To a great deal of the public, environmental movement is not the rebel alliance, but Moff Tarkin trying to tighten his grip.
And companies that make profits off of fossil fuels have armies of people scouring their data for the tiniest errors. Surprise surprise they find some on occasion.
This is essentially irrelevant. I work in a less controversial discipline, but if someone finds a flaw in one of my papers, "but you were paid by someone to look for it" would not remove the flaw or change how I should address it. Fossil fuel companies are paying people to scour science for errors -- excellent, good on them, it will help us improve the quality of our publications. So far as the public discussion is concerned, however, it is not the fossil fuel companies whose reputations are in questioned (everyone already thinks Big Oil is a bunch of rotters) so pointing accusing fingers at them does us much more harm than good.
when they can explain historical data that contradicts the theory...
It doesn't. It's dead on.
That's a rhetorical dodge. The models are based on historical data, and are a moving target, so just stating that the historical data concurs with our latest models is hardly surprising. The question, which is not answered so simplistically, is whether our computer models are overfitted or properly predictive. (Hopefully the latter, but we seem never to make that clear in these sorts of discussions.)
As it is, he fudging is so blatant that "climate science" is nothing of the sort...it's a Trojan horse for the same lod tired leftist government takeoff of economies. That trick never works.
Plenty of scientists are republicans or even further right. Yet, less than 10 (that's ten0 out of hundreds of thousands, disagree with the simple finding that humans are altering the average global temperature of the planet.
You're misreporting that rather badly. A small proportion of climate scientists disagree, but plenty of other scientists do. Vastly more than 10 (no I'm not going to "out" my colleagues, but yes I do personally know plenty). It's very important not to misrepresent the views of the field as being the views of everyone in every other field too. Otherwise it seems like we're dishonestly trying to gloss over the selection factor (if you've taken up a career in that part of science over any other, you probably think it's important).
Either all the wind turbine makers and solar panel manufacturers have a hell of a lot more money than we thought and are using it to bribe the scientific community on a scale unprecedented in human history, or we really do have a problem.
The problem we have, particularly as scientists, is that the political left has tried to co-opt us. Academics are naturally a little left-leaning (more of the free marketeers among us go into industry labs than universities), so too many of us have let them get away with this. The right of politics is centred on individual freedom from the state; the left is centred on collective action and solidarity (more publicly funded services and redistribution). The left is politically dependent on applying social pressure that you as an individual ought to be a part of collective action. "For the sake of the planet" is an emotive and strong argument from that angle, so the left side of politics has taken it up, all guns blazing. "For the sake of the planet" we must raise taxes on the industries we collectively disagree with and subsidise those we approve of. "For the sake of the planet" individual transportation (cars) must be economically discouraged and collective transportation (public transportation) subsidies must increase. "For the sake of the planet" the state (collective action) must spend more to employ people in science and environmental management, while private investment (for-profit corporate labs and private land ownership) must be distrusted and discouraged... We have become the tool of choice for the left to argue for greater control of the economy by the state. And it has been at the cost of science's credibility as an apolitical endeavour.
