‘Where does she think electricity comes from? Unicorn farts?’
Well...if the environuts actually got a brain somewhere and boosted the use of nuclear power, that would be a realistic way to reduce CO2 emissions. Granted, that looks quite unlikely at the moment.
‘And how does one go about reducing something that doesn’t exist?’
CO2 exists, and if nothing else ocean acidification is a real effect. Personally I think manmade global warming is a minor effect, and probably on hold for 20-30 years due to the current solar Grand Minimum. Regardless, there’s nothing wrong with letting natural market forces, as opposed to heavy-handed government subsidies (sigh), move things towards cleaner and more efficient technologies.
What I’d like to see is better analysis of the overall environmental impact of cars like the Volt. I recall a study that said that you could buy a Hummer and drive it for about 100K miles before reaching the total equivalent environmental impact of a new Prius hybrid, mainly due to battery manufacture.
There is also of course the “death factor” of driving a small car on roads alongside plenty of larger vehicles. Natural selection may work against the environuts to some extent...
I tend to agree although ocean pH varies widely and the fauna and flora adapt. The real warming from manmade CO2 increases is small and mostly beneficial. Like you said, the low solar activity puts us at risk of cooling right now.
