Tuesday’s protest came as the fate of a landmark lawsuit brought by young climate activists remains in doubt. Earlier this month, the Supreme Court allowed the case to proceed, but ruled that lower courts could continue to weigh in on its fate. On Thursday, the 9th Circuit Court of Appeals put a temporary stay on the case while it hears a challenge from the Trump administration. The 21 young activists launched their lawsuit under President Obama, arguing the federal government has failed to take necessary action to curtail fossil fuel emissions, violating their constitutional rights.
