Dan Walters, a columnist for the Sacramento Bee, wrote at the time of AB 32's consideration that, "Let's assume that global warming is a fact … the lack of a true global commitment is what makes AB 32 an essentially symbolic act. Even if the state's carbon emissions were reduced to 1990 levels as decreed, it would mean nothing if other major economies didn't join the effort."
AB 32's scheduled reduction of emissions is so stringent, it will essentially require action equivalent to the removal of every car, bus, and diesel truck off of the state's roads on top of a sharp reduction in commercial airplane and diesel train transportation. This is the backward thinking of REP et al.
Of course, all of this is par for the course for Harman. No doubt many people are aware, after Harman's recent campaign for the seat, that he has history in the enviro movement as a stalwart supporter of Amigos de Bolsa Chica and author of a now-infamous diaper tax for recycling.
