I understand. That said, in retrospect, we seem to be well ahead of "X will happen by Year Y" predictions. I guess my point is, better safe than sorry. Because as it is, we're fast-tracking to worst case.
You won't find the answer and that should make the most critical thinkers amongst you to question how much you actually can rely on much of these predictions about the future 30-80 years out.
It seems like that would be a great place to start if you want to convince people that they should spend a lot of money on something that isn't even demonstrated to be a problem we can't handle already now.
What are you ready to do, who's money and freedoms are you ready to spend on being "safe rather than sorry"?
This is the real question we should be asking ourselves.
I said nothing about CO2, who and/or why.
