Although I am sometimes leery of the accuracy of Wikipedia, this very short article is interesting:
https://en.wikipedia.org/wiki/Modern_Maximum
Basically, warm temperatures started in 1914, peaked in the 1950s and probably ended in 2000. And these sorts of ups and down are perfectly natural and just the way the sun works.
In other words, this short article completely leap frogs over the hoax that is Global Warming, and simply tells the truth.
And, yeah, as we leave this Maximum period, we’re probably heading into a Minimum which might be very bad.
Sunspots are actually cooler than the surrounding sun, which is why they appear dark.
