@Proton2: I don't think we have the luxury to just sit it out. We are spending trillions of dollars on this non-issue. Even if it was an issue, that money is not going to make a bit of difference even by their own assessments.
I just think it could have been better spent, better to have not spent it at all as we are in a crisis.
What difference does it make if trillions are being spent to solve environmental problems as opposed to anything else? The goal is to make the quality of life better for the inhabitants of this planet. You make it sound like "spending money" causes wealth to vanish into thin air. That's not the case at all. When money is spent, it gets moved around, which is actually a good thing. As far as I'm concerned there's no such thing as wasteful spending. What is wasteful is unnecessary consumption of natural resources. If the goal of spending all this money is to reduce or eliminate consumption of natural resources, I say "waste" all the money that you can to achieve this goal. Money never disappears, but natural resources do.
I think if you are a true environmentalist, you should have a firm belief in the capitalist system. Only thing that can clean up the environment is wealth.
The (current) process of creating wealth destroys the environment.
