Our overheating world is likely to break a key temperature limit for the first time over the next few years, scientists predict.
Researchers say there’s now a 66% chance we will pass the 1.5C global warming threshold between now and 2027.
The chances are rising due to emissions from human activities and a likely El Niño weather pattern later this year.
If the world passes the limit, scientists stress the breach, while worrying, will likely be temporary.
Hitting the threshold would mean the world is 1.5C warmer than it was during the second half of the 19th Century, before fossil fuel emissions from industrialisation really began to ramp up.
The 1.5C figure has become a symbol of global climate change negotiations. Countries agreed to "pursue efforts" to limit global temperature rises to 1.5C under the 2015 Paris agreement.
