Via AP: The United States government is becoming increasingly isolated on climate change. On Tuesday, the Syrian government, mired in war and the last United Nations country not to sign the Paris accord, announced it would sign the pact. That means the United States will be alone when it pulls out. State Department spokeswoman Heather Nauert responded to the Syrian decision by attacking its government. "If the government of Syria cared so much about what was put in the air, then it wouldn't be gassing its own people," she said.
