Read here, here and here. California is the epitome of the leftist/progressive/environmentalist 'car-plane-train' wreck that has devastated the bountiful economy of California. Once liberal environmentalists get their way, the environmental bureaucrats are hell bent to destroy economic activity in the name of their green-religion.
California's CARB (California Air Resources Board) has done to California what the IPCC wants to do to the United States - cripple economic opportunity and bankrupt it.
And California's environmental scare-mongering fanatics are pursuing this course of action despite overwhelming scientific evidence that the air quality has improved dramatically since the 1980's.
