California set an ambitious goal for fighting global warming. Now comes the hard part

The L.A. Times reports:

When Stanford University energy economist Danny Cullenward looks at California’s policies on climate change, he sees a potential time bomb.

The state wants to slash greenhouse gas emissions so deeply in the coming years that oil refineries and other industries could face skyrocketing costs to comply with regulations, driving up gasoline prices until the system loses political support. If that happens, an effort touted as an international model for fighting global warming could collapse.

Not everyone agrees with Cullenward’s assessment, but it reflects how experts, officials and lawmakers are starting to reckon with the state’s steep ambitions and the understanding that its current policies may no longer be adequate. Although California has been gliding toward its initial goal of reducing emissions to 1990 levels by 2020, it must cut an additional 40% by 2030 under a law signed by Gov. Jerry Brown last year.

“It’s going to take bold proposals to get us to where we need to be,” said Cullenward, who has helped shape legislation in the Capitol.

The religious story of the day.
