By approaching 2100, a world set for 3.4˚C will, on present trends, probably be the reality confronting our descendants—slightly less warm than looked likely a year ago, analysts think. That's the good news, you could say.
But the bad news is twofold. First, this improvement in planetary prospects will still leave the global temperature increase more than twice as high as the internationally agreed target of 1.5˚C. And secondly, it depends largely on the efforts of just two countries—China and India.
