Palaeontologist Tim Ewin is standing in a quarry, recalling the calamity that's written in the rocks under his mud-caked boots....
...The misfortune that struck this place 167 million years ago has delivered to him an extraordinary collection of fossil animals in what is unquestionably one of the most important Jurassic dig sites ever discovered in the UK....
...The quantities involved are astonishing. Not hundreds, not thousands, but perhaps tens of thousands of these animals that scientists collectively call "the echinoderms". It's a great name, derived from the Greek for "hedgehog", or "spiny", "skin". What is a sea urchin, if not an "underwater hedgehog"?

The Jurassic is of great interest. The carbon dioxide in the atmosphere was far greater than we have today, and yet the world did not end as predicted by modern day “environmental;ists.”
When cponfronted by this fact, these modern environmentalists just shrug, or say that human beings had not yet evolved and could not live then, whichi is hog wash. The fauna itself was copious and gigantic.
Most of Earth history the carbon dioxide concentration was a lot of more than today. Not just in Jurassic, all the time!
The level Greta is comparing to, and our environmental buddies think. it is optimal, was actually the record lowest level, ever.
Agreed,
I have to laugh at these Greta types when onfronted with this fact.
They ignore it or get REAL angry.
Their lies are immediately exposed.
I use this fact repeatedly to illicit exploding heads.
So was Oxygen
atmosphere had about 35 percent oxygen compared to today’s 21 percent. https://www.usgs.gov/
And where exactly do scientists think the huge amounts of carbon necessary for the giant and copious flora of that age to spring up out of the ground, and flourish the way it did, came from?
Here’s a hint. It didn’t come from the water, the dirt, the rocks or any other mineralacious material.
PING
it came from volcanos maybe? Carbon stored in rocks, melt, carbon dioxide emmisions then broken down to o2 and carbon?
It comes from the air.
The carbon-based life forms that are the plants around us absorb CO2 from the atmosphere, break it up into oxygen and carbon, emit the oxygen back into the atmosphere, but retain the carbon. Plants use the carbon to physically grow and build their very structure-—the same carbon they derive from the CO2 they absorb from atmospheric air.
Look at an oak tree. The carbon in that wood literally came from thin air!
“carbon dioxide emmisions then broken down to o2 and carbon”
__________
I see now you’ve got it of course but many don’t make the connection.
More CO2 in concentration in the atmosphere flat out means a greater volume of vegetative growth, all else being equal. It’s a good thing one would think. But no. We need to see a slow uptick in atmosphetic CO2 concentration from drastic post-ice-age lows as a telltale sign of the inherent earth-damaging nature of the human race.
