Like any religion, climate change has its share of fanatics, heretics, and agnostics. With all the arguments that go on I now realize it shares another characteristic with religion - all points of view are unprovable.
The believers quote the evidence, the deniers claim those sources are unreliable, including the official line taken by governments. If you can't trust your government, who are you going to believe? Whatever evidence appears from any imaginable source, the other side with rubbish it, and so the argument never ends.
There are too many fanatics that damage the real debate. There is more than one solution - personally I think we should look at technologies to engineer a solution, to modify the climate and/or better cope with a changing environment, rather than put all efforts into the single-minded persuit of trying to avoid a problem that may already be too late to stop. There's a subculture of people who want everyone to religiously practice self-denial and live a pre-industrial utopian existance - even if we were to invent a way to fix everything tomorrow.
I will not live long enough to see for myself whether this whole thing was true. Perhaps the climate is changing, but the rate is in question. Perhaps it is man's fault, perhaps a natural cycle.
It becomes a question of morality - do we take action that may save us, or that may be futile and hold us back. Just like a religion I do not know and indeed cannot know which God to worship, and so I put my head down and try to fit in.
Do we put all our efforts into reducing CO2 output? Can we protect our way of life and the earth's massive population forever? I don't think climate change threatens the existance of the human race. We are a tough species, we will adapt and survive, through an ice age or the opposite. It's just a matter of how many people die. Then again, if it turns out to be a fantasy and money spent managing emissions is really a waste, others will continue to die every day from starvation, lack of clean water, disease - things that could be prevented using the money we spend on reducing emissions.
I think the climate change idea is very fashionable, perhaps too much. A lot is spent on it that could do more immediate good elsewhere. A lot of people are making money from it, and when that happens you can never tell what to believe.
