Can you point to any scientifically demonstrated conclusion on how much humans affect climate via CO2 emissions? It's definitely some, but how much?

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.
