Global warming during a "greenhouse interval" ultimately led to the start of the human race, scientists believe.
New research suggests that sea temperatures of around 25C (77F) and a lack of permanent polar ice sheets fuelled an explosion of species diversity that eventually led to the human race.
Scientists made the discovery while looking for clues in tiny fossil shells in blocks of Shropshire limestone thought to be around 510 million years old.
The timeframe is referred to as the Cambrian explosion, when representatives of all the major animal groups first appeared.
The surge in diversity allowed life to evolve into a multitude of complex forms, including fish, reptiles, birds and mammals.
Scientists previously thought the Cambrian explosion must have been fuelled by warm temperatures, but the evidence has been lacking so far.
This new findings suggest it was a "greenhouse interval" when high levels of carbon dioxide filled the atmosphere and temperatures soared.
The findings appear in the journal Science Advances.

So the following ice age led to the decline of the human race?
So, Glowball Warming is a GOOD THING, right?................
Is there anything that the great god Global Warming cannot do?
So there were automobiles on earth before life on earth? Who knew?

Grampa!
Until 40 million years ago, there was no ice on the poles.
South America separated from Antarctica. Now a polar current of water formed, and a parallel air current with it.
Antarctica shifted from like modern Alaska to a deep freeze, two miles of ice at the poles. This cooled off the entire planet 10°F or so.
Be for that, rain forests circled much of the equator and what we think of as “temperate” zone, though there were deserts and swamp.
Historically speaking, we have a long way to go before we warm up to normal.
I don’t care who you are, that there’s funny.
Oh shut up! Ever heard of GOD?

That’s backwards and hyperbole. Temperatures go up first, then CO2 follows. And temperatures didn’t soar, they went up a few degrees gradually.
New research suggests that sea temperatures of around 25C (77F) and a lack of permanent polar ice sheets fuelled an explosion of species diversity that eventually led to the human race.

Real uncorrupted scientists have always called warm periods optimums.
We are currently in an ice age.
However, we’re in an interglacial warming period called the Holocene Optimum.
Interestingly, the last interglacial was warmer than this one, and Al Gore didn’t have his fleet if carbon spewing SUV’s and private planes back then.
So, Glowball Warming is a GOOD THING, right?................

Not necessarily. The human race also led to Democrats.
“Not necessarily. The human race also led to Democrats.”
Bummer.
I will go with God’s word over man’s “wisdom.” God created man 6000 years ago.
There are alternate warming and cooling periods. Not caused by man.
Thanos did it.
The article described some scientific data showing that temperatures were higher 500 million years ago, but it says nothing about high CO2 levels back then. How would they conclude that the higher temperatures were associated with high levels of CO2? It appears that they’re just speculating about this to try to connect it to the modern “theory” of AGW.
but now Global Warming is Dead , Trump stopped feeding it Cash
