The Syrian government has reportedly signed the Paris climate agreement leaving the United States of America the only country not being committed to tackle climate change.

Syria signed the Paris Agreement during the UN’s COP23 conference on climate change that is held in Bon, Germany from November 6-17.

The Syrian government was initially unable to sign the internationally-endorsed pact due to war. However, with the war coming to an end, Syria was able to join the Paris Agreement.

The agreement sets out a goal to stop global temperatures from rising more than 2°C above pre-industrial levels, a crucial threshold above which dangerous changes to the climate are likely irreversible. Such act requires the world to achieve net zero greenhouse-gas emissions by about 2050.

Back in June, U.S. President Donald Trump announced that the U.S. would withdraw from the Paris climate accord, weakening efforts to combat global warming and embracing isolationist voices in his administration who argued that the agreement was a pernicious threat to the U.S. economy and its sovereignty.

“I was elected to represent the citizens of Pittsburgh, not Paris,” Trump said.

“At what point does America get demeaned? At what point do they start laughing at us as a country?” he said. “We don’t want other leaders and other countries laughing at us anymore. And they won’t be.”
