YOU read too much into the argument, buddy.
Let's say the rest of the world continues on and does NOTHING, but the US acts as a "leader", and institutes a program to reduce CO2 emissions. Quantify what that sacrifice would be, how much it would cost and what the effect actually would be. Give a range of plans with different costs and benefits, and propose it. Jumping up and down like a child screaming the "sky is falling" doesn't help. Use that scientific method you claim to love so much, and bundle it with some math and good reasoning, if you can.
I think there is low hanging fruit which would cost little and reduce emissions. Start there.
