Meanwhile, in California, Governor Jerry Brown has declared a state of emergency Wednesday in a Los Angeles neighborhood where an uncontrollable methane gas leak has spewed more than 150 million pounds of methane into the atmosphere. The declaration comes 10 weeks after the leak was detected. Environmental advocates are calling it the worst environmental disaster since the BP oil spill. Methane is a powerful greenhouse gas that accelerates global warming. The company responsible, Southern California Gas Company, says it could take three to four months to stop the leak.
