The New York Times' Adam Liptak writes that the U.S. Supreme Court will hear oral arguments Monday on the ability for President Obama's administration to take executive-only action on climate change. The justices will decide if the executive branch went too far in regulating greenhouse gas emissions from stationary sources like power plants. The issue taken up by the court, Liptak reports, is whether the Environmental Protection Agency "'permissibly determined that its regulation of greenhouse gas emissions from new motor vehicles triggered permitting requirements under the Clean Air Act for stationary sources that emit greenhouses gases.'”
