In other words, they acted just like all the anti-AGW people are acting right now.
There were scientists who believed the continents were static, but there were not thousands of papers "proving" that was true. There were scientists who didn't believe in microorganisms, but there were not thousands of papers "proving" they don't exist. There were scientists who believed in the aether, but there were not thousands of papers "proving" it existed.
In every case of this nature the anti-AGW try to cite, a large number of scientists assumed that something was true when it was not. Then some rebel got up and said "i think it works in some different manner!" and caught a lot of flak for it, which is unfortunate but part of the human condition. However despite the arguments and entrenched positions and pride and stubbornness, when actual science started being done the truth came out. In all the cases once papers started being published the vast majority of them supported the viewpoint that we have not generally come to conclude is the correct one. Microorganisms exist, the continents do move, and there is no aether.
The anti-AGW people seem to be arguing that this is the sole case in history where as more and more science has been done, more and more scientists have apparently faked their results in order to support mistaken beliefs. In some cases they argue that it's because they're being funded by "pro-AGW" bodies, in particular governments, when the corporations who are firmly anti-AGW have far deeper pockets and have actually been caught funding scientists to promote certain views.
In short, it's good to have an open mind, but not so open that your brain falls out. When new ideas come out it doesn't hurt to question them, but the anti-AGW people long since passed the point of reasonable doubts being aired and moved into denialism and conspiracy theories.
