The Supreme Court has agreed to make a decision on President Obama's executive actions regarding emissions regulations. The high court will review a lower court's upholding of the EPA's ability to regulate greenhouse gases in power plants and factories. The EPA's authority, granted under the Clean Air Act, is an effort to stave off climate catastrophe and its upheaval would put Congress in charge of figuring out how to curb dangerous emissions. Because they're real good at getting things done.
