This does not mean the world would cross the long-term warming threshold of 1.5C above preindustrial levels set out in the 2015 Paris Agreement.

But a year of warming at 1.5C could offer a glimpse of what crossing that longer term threshold, based on the 30-year global average, would be like.

With a 66% chance of temporarily reaching 1.5C by 2027, “it’s the first time in history that it’s more likely than not that we will exceed 1.5C,” said Adam Scaife, head of long-range prediction at Britain’s Met Office Hadley Centre, who worked on the WMO’s latest Global Annual to Decadal Climate Update.
