> Once new evidence was found, the new explanation was quickly adopted into the scientific consensus (so it remained the best model for reality). The problem with a direct comparison in this case, that we ought to accept the consensus and be as dismissive about anthropogenic climate change skeptics as we are about someone who still claims that the Sun revolves around the Earth, is that in the case of stomach ulcers, the result is easily testable and reproducible. Much harder for something as complex as the climate. Additionally, this issue is laden with political consequences on both sides so it's hard to accept objectivity on either side (very difficult for someone to obtain a grant inside the academic mainstream to study something that is contrary to accepted opinion, and very difficult for someone to obtain a grant from industry to study something that is in line with accepted opinion. not to mention the potential effects for fossil fuel and alternative energy companies)
