On this edition of Your Call, we discuss the 6-3 Supreme Court ruling that curtails the EPA’s power to force power plants to reduce carbon pollution. Those plants make up a quarter of greenhouse gas emissions in the US, according to the EPA. In her dissent, Justice Elena Kagan wrote, “The Court appoints itself — instead of Congress or the expert agency — the decisionmaker on climate policy. I cannot think of many things more frightening. Whatever else this Court may know about, it does not have a clue about how to address climate change." This case is the product of a coordinated, multiyear strategy by Republican attorneys general, conservative legal activists and their funders to use the judicial system to rewrite environmental law, weakening the executive branch’s ability to tackle global warming, writes New York Times reporter Coral Davenport.
