Yes, I agree about the compulsion to link CO2 and climate warming in general. The subject is still in its infancy, and most scientists have egos (publish or perish, don’t you know!) which translates into a rush to garner headlines.
As you may have guessed, I have a geeky desire to read about paleontology and geologic past events. One of the books I have is by Peter D. Ward, Out Of Thin Air (2006), which discusses the Permian oxygen crash which could have caused the massive, catastrophic extinction associated with that period.
His book is NOT an exciting read, in fact it is quite dry. But he does a very good job of explaining why dinosaurs evolved with the ability to husband oxygen in their bodies, with birds being the connection between the present and the past. He also explains why and how the oxygen crash may have happened 251Million years ago. Chapter 7 is the most interesting part of the book. Ward also details the rise and fall of CO2 as it corresponds with oxygen pecentages in the atmosphere.
Maybe that’s what I meant! The ole memory is getting a little aged...
46th Post. I was getting worried.
I also have not seen anyone ask, "which came first: the temp rise or the CO^2 rise?"
Also, they state that the temp rose 10C over a 175,000 year period. If it weren't a rise, I might have called that 1/17C per MILLENIUM change (ahem) "glacial".
And, finally, the piece de resistance: But by 130,000 years into the PETM, Sifrihippus had shrunk down to only about 8.5 pounds (3.9 kg), the size of a small housecat. These humble horses then experienced a size rebound, bulking up to about 15 pounds (7 kg) in the last 45,000 years of this warm period, putting them on par with the average bichon frise.
These things went from 12 -> 8.5 (a 1/3 decrease in size) over a 130,000 year period, as it warmed; then, as it FURTHER warmed, (or at least remained as warm) in 1/3 the time, went from 8.5 -> 15...NEARLY DOUBLING in size!
Warmth is amazing! It shrinks AND it expands!
Penguins and polar bears are next!
The horses had to get small to fit into the cars they needed to drive in order to stop global warming. This all makes more sense now!/s/

Whoops, missed your ping last year.
The big question...
Could they be litter box trained??
If so, a see a potential market here - kind of like those little annoying dogs that girls carry in purses, but cooler - way cooler!
A pony walks into a bar and says “Bartender, may I have a drink?”
Bartender says “What? I can’t hear you. Speak up!”
“May I please have a drink?”
“What? You have to speak up!”
“Could I please have a drink?”
“Now listen, if you don’t speak up I will not serve you.”
“I’m sorry, I’m just a little hoarse.”

Sorry to say that you got this one wrong, GrandJediMasterYoda.
Al Gores caveman ancestor, Croman Gore, was busy inventing the RockNet in those days so he was not able to turn his attentions to the daily weather.
P.S. Get a shorter name
Amazingly, no one has correlated original furlong length, to the breed size. Idiots.
Well, look at it this way - 3 foot humans would relieve overcrowding (sarcasm)
The same thing happens when I put my clothes in the dryer!
If global warming shrunk horses to the size of a cat, why are people taller now than they were back in olden days?
I’d like to see the supporting research on this one. Not passing the smell test yet.
