Remember, the US Senate voted against Kyoto 95-0.
The above remarks assume that human contributions to so-called greenhouse gasses in fact contribute significantly to global warming. I'm not convinced that's true. The above remarks also assume that any climate change that occurs will have deleterious effects overall. No one has any good idea about that, I'm confident.
Even with these two assumptions, though, curbing emissions through voluntary adopting poverty-- the green approach-- or through technology-- Samuelson's approach-- is not an option.
