If the "warmies" were sincere & serious...
They'd be up in arms over Solyndra & other "green" scams that just divert resources from ostensible efforts to solve the problem, to the pockets of well-connected crooks.
They would want to see any domestic restrictions/taxes on combustion energy accompanied by proportionate duties on imports of goods manufactured by CO2-generating energy, lest all the manufacturing simply flee overseas, & as much CO2 is made as ever. Strange how they're just OK with Chinese CO2!
They would not be attracted by schemes shown to maximize statism & tax burdens while haviong negligible effect on CO2 levels or "warming" like "cap & trade".
