California legislators really do seem to be poised to pass the modestly named Global Warming Solutions Act, which would require the state to bring greenhouse gas emissions back to 1990 levels (and how sad that that’s an ambitious idea). The Assembly has signed off and the Senate is expected to by midnight today; Arnold is on board. No doubt there’s a downside to this somewhere, but until we find it, it looks a lot like saving our species from extinction comes with an economic bonus: A new University of California-Berkeley study finds that going back to 1990 emission levels would boost the annual Gross State Product (GSP) by $74 billion and create 89,000 new jobs by 2020.
