We're gonna hit 1.5C warming soon

In short: yes. Within about a decade.

Sigh.

Ever since the 2015 Paris Agreement on climate change, the world has been aiming (perhaps futilely) to stay below 1.5C of warming above pre-industrial times. It has become a magic number, used in media headlines and academic papers as a key threshold. 

Looks like we're going to hit 1.5 for a single year sometime in the next 5 years, and consistently sometime in the early 2030s.

Yet another reminder to keep emissions low! A 'global stocktake' of how we're all doing on that is now underway, to be presented in November.
