Get ready for several years of even more record-breaking heat that pushes Earth to more deadly, fiery and uncomfortable extremes, two of the world's top weather agencies forecast.

There's an 80% chance the world will break another annual temperature record in the next five years, and it's even more probable that the world will again exceed the international temperature threshold set 10 years ago, according to a five-year forecast released Wednesday by the World Meteorological Organization and the UK Meteorological Office.

There's an 86% chance that one of the next five years will pass 1.5 degrees and a 70% chance that the five years as a whole will average more than that global milestone, they figured. “Higher global mean temperatures may sound abstract, but it translates in real life to a higher chance of extreme weather: stronger hurricanes, stronger precipitation, droughts,” said Cornell University climate scientist Natalie Mahowald, who wasn't part of the calculations but said they made sense.

And for the first time there’s a chance -- albeit slight -- that before the end of the decade, the world's annual temperature will shoot past the Paris climate accord goal of limiting warming to 1.5 degrees Celsius and hit a more alarming 2 degrees Celsius of heating since the mid-1800s, the two agencies said. The projections come from more than 200 forecasts using computer simulations run by 10 global centers of scientists.

Ten years ago, the same teams figured there was a similar remote chance — about 1% — that one of the upcoming years would exceed that critical 1.5 degree threshold and then it happened last year.  This year, a 2-degree Celsius above pre-industrial year enters the equation in a similar manner, something UK Met Office longer term predictions chief Adam Scaife and science scientist Leon Hermanson called “shocking.”
