The forecast is not good. Some 195 nations that signed the 2015 Paris climate agreement are meeting in coal-powered Poland for two weeks beginning today, aiming to iron out the pact’s details. Since that Paris summit, though, President Donald Trump, who continues to mock global warming concerns, has said America is abandoning the deal. But U.S. agencies agree that Americans’ mortality and economic well-being are threatened by climate change, adding weight to an October United Nations assessment. That means the rest of the world may end up picking up the slack, or pointing fingers.
