Syria signs Paris climate agreement and leaves US isolated

Syria has decided to sign the Paris agreement on climate change, the world’s final functioning state to do so. The surprise decision, taken amid a brutal civil war in the country, will leave the US as the only country outside the agreement if it follows through on President Donald Trump’s vow to leave.

Syria’s decision brings to 197 the number of nations signed up to the landmark 2015 pact on global warming, the first in more than 20 years of UN negotiations to bind both developed and developing countries to a clear limit on temperature rises.
