Michael Crichton made an interesting observation in 2003. I think it only partly explains why the science has been corrupted so badly by those pushing AGW (the other part being those trying to leverage the issue for economics both personal gain by creating a tradeable commodity via cap-and-trade as well as wealth redistribution):
"I think that you cannot eliminate religion from the psyche of mankind. If you suppress it in one form, it merely re-emerges in another form:”
You can not believe in God, but you still have to believe in something that gives meaning to your life, and shapes your sense of the world. Such a belief is religious.
Today, one of the most powerful religions in the Western World is environmentalism. Environmentalism seems to be the religion of choice for urban atheists. Why do I say it’s a religion? Well, just look at the beliefs. If you look carefully, you see that environmentalism is in fact a perfect 21st century remapping of traditional Judeo-Christian beliefs and myths.
There’s an initial Eden, a paradise, a state of grace and unity with nature, there’s a fall from grace into a state of pollution as a result of eating from the tree of knowledge, and as a result of our actions there is a judgment day coming for us all. We are all energy sinners, doomed to die, unless we seek salvation, which is now called sustainability. Sustainability is salvation in the church of the environment. Just as organic food is its communion, that pesticide-free wafer that the right people with the right beliefs, imbibe.
Eden, the fall of man, the loss of grace, the coming doomsday—these are deeply held mythic structures. They are profoundly conservative beliefs. They may even be hard-wired in the brain*, for all I know. I certainly don’t want to talk anybody out of them, as I don’t want to talk anybody out of a belief that Jesus Christis the son of God who rose from the dead. But the reason I don’t want to talk anybody out of these beliefs is that I know that I can’t talk anybody out of them.
These are not facts that can be argued.
These are issues of faith."
**And followers of that faith definitely try and silence the heretics, or discount them as biased.

However, the core guidance of the Church of being good stewards, as another poster mentioned, remains - conserving resources and minimizing waste to ensure the earth’s resources are shared as fairly as possible now and preserved for the future generations.
