According to the fact-checking/mythbusting website Snopes in 2019
“In 2014, weather reporter Évelyne Dhéliat of the TF1 television channel in France teamed up with the World Meteorological Organization to create a series of fictional weather reports imagining what the weather will be like in the summer of 2050. While these reports may have seemed far-fetched at first, a June 2019 heat wave across Europe showed that these temperatures are well within the realm of possibility.”

Ms Dhéliat had done this at the time of COP-20 (one of the many forgettable annual ‘last chance to save the world’ conferences that have been happening since Berlin 1995).

Snopes was on the case because of this tweet (back before the fash took it over and trashed it).

And fast forward seven years, and we have this

What do we learn
The changes we induced from
a) deforestation and then the burning of – er – industrial quantities of coal, gas and oil
b) continuing to do this after the scientists started saying we should really knock that off (in 1980s, or 1970s if you’re being pedantic)
are coming at us faster than ‘responsible’ (sober, reticent etc) scientists used to say they would. A captious and cynical observer could suggest that this implies that our self-confidence in understanding complex/chaotic systems once they go past certain ‘stable’ parameters is… how shall we say it to a family audience….”somewhat misplaced.”
The same somewhat assholish observer might also propose that we soothe ourselves with the idea that we can predict, because if we can predict, we can control, or at least prepare. Someone should tell them they’re dreaming.
This suggests that, as per Jason Bourne to the doomed journalist in the third (and equal-best) Bourne film “you have no idea what you are into here.”
This suggests that I was right twenty years ago when I did that spoof newspaper in the aftermath of Climate Camp

The weather map is not the climate territory.
The territory is gonna be terror, from here on. As per old Perce in January 1818
No thing beside remains. Round the decay
Of that colossal wreck, boundless and bare
The lone and level sands stretch far away.
