Except this isn't over the course of a day, it's a year.
Is this the same Europe that a couple of years ago had, of all things, an international climate change crisis meeting which was put on hold a few days because everything got so iced over with record cold that even rail wasn't an option for traveling and everyone was snowed in?
The current heat and drought in the Western US is a return to what had been the post-Ice Age norm. From the end of that till 1800 years ago, SoCal was hotter and drier than what we've been used to. 5300 years ago things cooled down enough that Bison Occidentales was able to live again in what is now New Mexico, as it had been too hot and dry for it to survive there for a period.
There have been other upticks and cool downs, and the only role fossil fuels played was still being unused underground.
