Thinking about climate change and other things just for the fun of it I googled the question above to see if I would get something sensible.
Sure enough, I got a lot of junk. That's to be expected.
What I did not expect was the first item. It was an article from Universe in 1999 by Greg Bryant named "The Dark Ages: Were They Darker than We Imagined?" I found the article fascinating.
We get so fixated on things like human caused global warming that we forget that catastrophic weather changes have been caused by natural forces through the ages.
It often gets difficult to remain rational with the pressures exerted by society.
