Climate Change Returns to White House Agenda with Biden Executive Order Steve Baragona President Joe Biden immediately began to reverse the Trump administration's policies on climate change with one of 17 executive orders signed Wednesday after his inauguration. That's in addition to the move to rejoin the Paris agreement to limit climate-changing greenhouse gases. After four years of federal disinterest in the issue, the order calls on all federal agencies "to immediately commence work to confront the climate crisis." Among its dictates is the cancellation of the Keystone XL pipeline, a project that perhaps more than any other has become a symbol of the rise and fall and rise of climate policy over the past three administrations. .
