Donald Trump’s administration is to reconsider the official finding that greenhouse gases are harmful to public health, a move that threatens to rip apart the foundation of the US’s climate laws, amid a stunning barrage of actions to weaken or repeal a host of pollution limits upon power plants, cars and waterways.
Trump’s Environmental Protection Agency (EPA) issued an extraordinary cavalcade of pollution rule rollbacks on Wednesday, led by the announcement it would potentially scrap a landmark 2009 finding by the US government that planet-heating gases, such as carbon dioxide, pose a threat to human health.
