I am a global warming skeptic. In relatively recent history, the time from about 800 to about 1300 AD is referred to as the “Medieval Warm Period”. This was the period of time in which the Vikings sailed to Greenland. They called it “Greenland” because it was a green land; the coastal areas of Greenland had a mild climate then.
Now, did the Vikings have SUVs and coal fired power plants and heavy industry polluting the environment then?????
“Now, did the Vikings have SUVs and coal fired power plants and heavy industry polluting the environment then?????”
No, of course they didn’t, silly - they had nuclear power plants at their secret locations, and later joined forces with the Knights Templar using their huge fortunes to build descent space ships, and together blew the join for greener pastures - which is why the Vikings, the Templars and their tresure dissapeared.
