A federal appeals court has rejected an effort by the United States government to halt a case against President Donald Trump and his administration. A group of 21 young people brought the case against the federal government. They accuse the Trump administration of violating their constitutional rights by ignoring the harm caused by climate change. The 9th U.S. Circuit Court of Appeals in San Francisco ruled against the administration on March 7. The court said the government had failed to provide enough evidence under federal law to dismiss the case. The lawsuit started three years ago in the northwestern state of Oregon. At that time, the case was directed against the administration of President Barack Obama. This is one of several cases seeking to have courts deal with climate change and its causes.
