NYT- 'When you talk about S.U.V.s and building bigger houses, you’re really talking about people’s consumption choices. Do you think changing those is an easier goal than decarbonizing?'

Vaclav Smil 'Well, we changed people’s consumption by letting them have their S.U.V.s. We can change people the other way. We could say, To save the planet people should drive smaller cars. If you drive a smaller car, you get a rebate. If you drive an S.U.V., you pay a surcharge. There are many ways to go around bringing rational goals.'

Smil acknowledges the problem of climate change- he is questioning the realism of the targets and means of achieving reductions- not the need for reductions.

Above Smil advocates rebates and other government funded incentives and directives to modify free market functioning.

Climate change denier Libertarians should acknowledge this.
