The 1.5C relates back to sometime in the 19th century, when global temperature data was minimal compared to today, one exception being the Central England data which shows nothing dramatic. After three years of La Niña, climate alarmists are relishing the prospect of an El Niño to revive their sagging crisis narrative a bit.

Our overheating world [Talkshop comment – BBC climate hype] 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 change in weather patterns expected this summer, says BBC News.
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. [Talkshop comment – the old correlation/causation confusion again].
And breaking the limit even for just one year is a worrying sign that warming is accelerating and not slowing down.
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.
Going over 1.5C every year for a decade or two would see far greater impacts of warming, such as longer heatwaves, more intense storms and wildfires.
But passing the level in one of the next few years would not mean that the Paris limit had been broken. Scientists say there is still time to restrict global warming by cutting emissions sharply.
