It appears that the video is a "YouTube Short", which is having trouble embedding on an external page, maybe because the aspect ratio is different from regular videos. I'll try it from here:
Doesn't look like it's working for me, either.
A summary:
The presenter claims that the climate of North America, 10,000 to 15,000 years ago, was like the climate of Antarctica is now. While not strictly true - the climate of CANADA and some of the northern US was Antarctic, entirely covered in ice, but the US, from about half way down in Ohio and southward of that line was more like Canada or Siberia is now - it's close enough for his premise.
He says that folks have some weird notion that there is a steady state for climate, and that is utterly wrong, which is a true statement. The one constant of climate is that it is always changing due to a plethora of variable interacting with one another.
He also says that the heat capture ability of CO2 is limited, and that most of the thermal capture is accomplished in the first 100 parts per million, which is also true. Beyond that, you reach a point of diminishing returns, where simply adding more CO2 does not capture the same amount of heat, but falls off. It's not a linear 1 for 1 capture for each new unit of CO2.
During the carboniferous period, our atmosphere had about 4 times the current level of CO2. If heat were captured in a linear fashion, all life on Earth would have ended other than extremophiles, because Earth's surface temperature would have been well over the boiling point - hotter at the equator, somewhat cooler at the poles. But, to the contrary, life flourished, and the Earth was a jungle-covered mess, which is why we have coal deposits now. Insects, amphibians, and fish nearly overpopulated, and the first reptiles came into existence.
Here's an attempt at posting just the link, so you can watch it on YouTube if it works:
