Syria recently announced at the international climate conference in Bonn, Germany that it will join the Paris Climate Accord.

Syria’s decision to join the international agreement makes the United States the only country in the world that is not honoring the 2015 climate change mitigation goals. President Trump announced that the U.S. would leave the agreement, which aims to keep global temperatures from rising more than 3.6 degrees Fahrenheit above pre-industrial levels, in June.

Nicaragua was the second-to-last country to ratify the agreement. The central American country initially voiced concerns that the Paris climate agreement did not go far enough to address climate change but decided to join in September.

The Sierra Club published a response to Syria’s joining, “As if it wasn’t already crystal clear, every single other country in the world is moving forward together to tackle the climate crisis, while Donald Trump has isolated the United States on the world stage in an embarrassing and dangerous position.”

Given that the U.S. is the second-largest producer of greenhouse gases, some experts wonder if the international climate goals can be reached without U.S. government support. More than 1,300 U.S Mayors, Governors, State Attorneys, businesses, investors and other prominent climate actors have communicated their continued commitment to the Paris Climate Agreement goals in the We Are Still In movement. The group, which makes up $6.2 trillion of the U.S. economy, will send numerous delegates to the the Conference of the Parties 23 to “show [ing] the world that U.S. leadership on climate change extends well beyond federal policy.”
