First up, I'm a climate change skeptic. That is because I'm skeptical about everything, I mostly believe in much of what I read about climate, but if presented with a coherent argument and evidence, I'd drop the idea in the mental trashcan that hold the (since disproved) Law of Conservation of Parity, "Active Oxygen", (doesn't exist either) and the non-quantum "laws" of cause and effect I learned as a child.
I am a scientist, not in any way an eminent one, but to me that is a discipline and a set of rules by which we try to work out the nature of the universe (if it really exists) and thus I will not believe anything of any kind ever that is "true because a lot of people believe it".
Even if 100% of people who are called "climate change scientists" (in itself a badly defined term and seemingly more a reflection of the political views of a writer than an objective state), I would not believe in Climate Change the way Christians believe in Christ, Moslems believe in Allah or so many believe in the literal truth of holy books, or the Hitch Hikers Guide to the Galaxy.
Part of my being a scientist is that I've tried to understand some of its history and one of the clearest patterns has been that just because a lot of people believe in something like flatness of the world, that germs were just the imaginings of over-excitable europeans or as Lord Kelvin (as in the unit of temperature) and nearly all 19th century physicists that the Sun could not be more than a few million years old because no energy source could power it that long, that doesn't mean it is true.
Every time some well meaning fool says "it must be true because a lot of people I agree with, agree with me", or fudges scientific data to get a result that makes them feel good about themselves in front of their peers, then we damage science itself.
