Can the world still keep warming within the Paris limit?

For nine years, Guterres insisted the Paris limit was still alive. Last year, before a major speech, he consulted scientists and calls their answer an enormous shock: Scientists told me you cannot say that because that's no longer true.

The UN now tries to limit how far past that threshold the world goes. He sets the planet's need for a long-term view against the short horizons of many political systems. But it's not the world that's failed, it's the political leadership that's failed.

Now he will tell leaders at the Antalya summit that the moment for delay has passed. This is a moment of truth. We can no longer wait, we can no longer have endless discussions in which everybody tries to push the responsibility to someone else.
