On Wednesday morning, four-term California Governor Jerry Brown issued an executive order that aims to reduce California's greenhouse gas emissions by 40 percent below 1990 levels by 2030. Brown called it the most aggressive GHG target by any North American government to date.
Under Brown's guidance, California has made ambitious steps to confront climate change, which has contributed to the state's current water woes. But this is his boldest gambit yet. His carbon reduction target is even more aggressive than the Obama administration's, which aims to cut carbon dioxide emissions by 28 percent below 2005 levels by 2030.
