Guardian: Paris climate change agreement: the world's greatest diplomatic success

With all 196 nations having a say, the UN climate deal, with all its frustrations and drama, has proven that compromise works for the planet

In the final meeting of the Paris talks on climate change on Saturday night, the debating chamber was full and the atmosphere tense. Ministers from 196 countries sat behind their country nameplates, aides flocking them, with observers packed into the overflowing hall.

John Kerry, the US secretary of state, talked animatedly with his officials, while China’s foreign minister Xie Zhenhua wore a troubled look. They had been waiting in this hall for nearly two hours. The French hosts had trooped in to take their seats on the stage, ready to applaud on schedule at 5.30pm – but it was now after 7pm, and the platform was deserted.
