Less than three months ago, the Supreme Court allowed a landmark climate change lawsuit against the federal government to proceed, despite misgivings about the “striking” breadth of the case filed by nearly two-dozen teenage plaintiffs. This week, the high court must decide again whether to delay the case just days before it is set to go to trial in federal court in Oregon. On Friday, Chief Justice John Roberts issued an order on behalf of the Supreme Court to stay the proceedings pending the young plaintiffs’ response to the government’s request to narrow the case.
