President Trump on Tuesday signed an executive order seeking to undo Obama administration policies that were intended to address climate change. The White House had announced the move in advance, so it came as no surprise. In the sweeping order, Trump told the Environmental Protection Agency to review the Clean Power Plan, which limits greenhouse gas emissions from power plants. He also lifted a ban on new coal leases on federal lands, which Obama put into place for three years in 2016 so the program could be modernized. Trump said the changes would help revive the coal industry and recover lost jobs. Former Vice President Al Gore, an environmental activist, called Trump's order "a misguided step away from a sustainable, carbon-free future for ourselves and generations to come."
