I always laugh when people claim there’s some vast, worldwide conspiracy of scientists who made up climate change in an attempt to get pots of money and/or force the world to submit to a totalitarian government made up of crazed scientists.
For one thing, there’s not a lot of money in science. Researchers have to compete with many others to gain access to what research funds are available, and those funds are spent on infrastructure, staffing, and consumables: doing the research, in other words, rather than providing crystal goblets and solid gold plates for scientists to dine from.
For another, trying to get a bunch of scientists to organise for any reason is like herding cats – they’re fiercely independent and mostly totally engrossed in their work. They’d also rather have root canal surgery than do any more administration than is absolutely necessary, so the idea of them willingly choosing to rule the world is quite ridiculous.
Finally, the idea that any substantial group of scientists would choose to lie about their research, or would be allowed to get away with it, is also ludicrous. Scientists do what they do because they’re passionate about it, not because they want to institute a new world order. Even if one or more wanted to lie, the system of peer review makes it highly unlikely that they’d get away with it.
And while peer review is not perfect, scientists who attempt to replicate flawed work soon find that it’s flawed (and they do try: scientists will always test anything and everything). Proving the entire scientific establishment wrong is a great way to build a stellar reputation fast, compared to the decades spent building a reputation on solid incremental work.
There are a plethora of other denier arguments, so here you’ll find a collection of articles where you’ll find rebuttals to these arguments, some useful graphs, and an interesting article about the source of much climate denier publicity.
