Taking the Supreme Court's Temperature on Global Warming

Court watchers and environmentalists are waiting with bated breath for the U.S. Supreme Court to rule on West Virginia v. EPA, the Court's most important climate change case in a generation. The issue in that case is what, if anything, the U.S. Environmental Protection Agency (EPA) can do to regulate carbon emissions from power plants and factories. Last week, conservative states asked the Court to intervene in another climate change case. How the Court responds could give us hints into just how far the activist conservative majority is likely to go in the West Virginia case.
