The term "climate change" has been politicized and is thus now toxic.
If you ask questions, you are deemed a science denier by the left, mostly by those that deny Biology to gain social media points by the deranged leftists and to keep their jobs.
And so, real science is now practically non-existent now when it comes to this topic as even scientists that point out the flaws in what is being said are now being fired, discredited, removed from studies/positions...
The last ice-age ended around 11,700 years ago. right around the time when those that are now natives of the America's crossed the Bering-Straights which is now impossible. Why? Because the planet has been warming and melting all the ice from the ice age causing the oceans to rise and cover it...oh, wait that happened around 11,000 years ago.
Through-out recorded history we have examples of this continuing. Egypt used to be a fertile land, green as a mother fucker...the land of "plenty".
They found proof that much of what is now the black sea, was actually dry land and around 5,600 B.C, over-flow from the Caspian Sea flowed into it from glacier melting.
We have recorded proof of "polar vortexes" back in the 1800s when they bothered to actually start recording weather events...looks like they are not new and caused by humanity after-all.
We already know that there was a vast warming period at the time of the last ice-age called "late glacial", an unexplained sudden increase in warming over a few centuries.

Why did we have such a warm midieval period and get a mini ice age from 1650 to 1850?!?

Can all this just be cyclical? Dont ask...or you are a science denier.
