The U.S. is failing at both symbolism and action. We are the only country led by someone who does not think climate change poses a real threat, and our problems go beyond the president. Our Republican-led Congress prevented the Paris Agreement from asking countries to make stronger initial pledges in the first place: World leaders knew the American Republicans would never ratify a binding agreement, so they settled for the softer one. More recently, 22 Republicans in Congress have written a letter to Trump imploring him to withdraw even from that. Attorneys general from 10 Republican-led states have done the same. We were never going to lead the way on climate change, even under Obama, because we are held hostage by a GOP that refuses to acknowledge the reality of the threat.
