California is suing the Trump administration over its decision to roll back the endangerment finding , the U.S. government’s longstanding scientific conclusion that planet-heating pollution seriously threatens Americans, state officials announced Thursday. Its rollback will disrupt the regulatory landscape and result in significant increases in greenhouse gas emissions, which drive climate change, they said. The lawsuit will ask the court to vacate the EPA’s repeal and restore greenhouse gas emission standards for vehicles. “The science doesn’t lie: Climate change and [greenhouse gas] emissions are harming public health and causing devastating and ever-worsening disasters. But many experts say reducing those emissions is critical for curbing climate change, as the transportation sector is the largest source of greenhouse gas emissions in the U.S.
