The scientists seem to downplay or ignore the Medieval Warm Period.
I’m no scientist, but I have a feeling that there are elements to climate cycles which we just don’t understand.
Heck, we have had numerous ice ages in earth’s history.
Probably there have been periods of warming too.
During the last ice age, Chicago was buried under a mile of ice.
Researchers in Antarctica have found coal. Coal is formed from deposits of organic matter, such as vegetation. At one time Antarctica cleary was not a frozen wasteland.
So, perhaps these guys don’t truly understand all of this, but they have a desire to put society into a straight jacket in various policies, so we can “fight global warming”, and make liberals happy.
Antarctic had coal deposits for the same reason they found Mastodons with warm climate vegetation in their digestive tract.
The earth’s crust rotated about 30 deg (N to S) putting Antarctic at the south pole and the Mastodons (in Russia) near the new N pole. They basically froze to death within a day or two.
Also explains the Great Flood because if both poles melted they would have done so quickly causing cities to be covered with over 400 feet of water (in some cases - within days or a couple of weeks & other locations experiencing flash flood that wiped out everything instantly.

That sums it up better than you may think, Dilbert San Diego. Neither you nor I nor anyone else has anything like a clear, comprehensive picture of our planet's climate. Genuine climate scientists know isolated bits and pieces; how they fit together, however, remains unknown, nor is there any reason to believe they have more than a small percentage of all the bits and pieces that will eventually be known.
The climage pseudo-scientists who jumped on the "anthropogenic global warming" band wagon did both their own corner of science and real scientists the world over a horrible disservice. They whored for Marxists in the name of science. Do you suppose they're sorry? Sorry they got caught, anyway.
Do you suppose other fake scientists are already working on the next impending imaginary disaster for the sake of advancing the anti-religion of Marxism? I'm sure they are.
Antarctica froze over 14 million years ago — central Antarctica has pretty much been frozen since the the last real ice age or the peiod known as snowball earth prior to 650mya.
Right down to the name change. Remember 10+ years ago it was called The Medieval Climate Optimum.
You can't call anything to do with warming "optimum" anymore
I knew the Sahara had been fertile grasslands just a few thousand years ago - there are cave paintings of men hunting large herbivores in lush grass, in what is now barren waste. Well into historical times, Northern Africa was the bread basket of the Roman Empire. Literally, as the grain that was shipped to Rome and distributed as bread to the Roman masses came from there.
But I recently saw a program about the Sahara, that said it not only used to have grass, but vast river systems, and lakes that rivaled the Great Lakes - in surface area, if not volume. It also said that the Sahara has swung from one extreme, to the other, many times, probably due to variations in the Earth's tilt. We are at a very dry point in the cycle, but 10,000 years ago the Sahara was lush and green, and it will be again 10,000 years hence.
The coal was probably formed at least 200 million years ago when Antarctica was not located at the south pole.
