The Pliocene: The Last Time Earth had >400 ppm of Atmospheric CO2

The "glacials" are complete bullshit.

Liar you are...

Since Co2 does nothing, what does cause Earth climate change?

The first part is understanding what is climate and what is weather. Climate is the parameters of Earth that allow certain ranges of weather. We don't get Cat 10 canes now, but we would if Earth had no ice. What are the parameters of climate that can change? Ocean levels Atmospheric...

Apparently we really need a "debate" over the term ICE AGE because y'all are all wrong...

What is an ICE AGE? Most apparently still believe it is a terrifying horror movie event where Earth all at once freezes up. The data has never supported such a scenario. Since 2010, there has been a massive effort to re-write Earth climate history into a series of rapid "glaciations" and ice...

So what causes an ICE AGE?


Land moving near the poles. When land gets to within - roughly- 600 miles of a pole, as Greenland just did, the annual snowfall ceases to fully melt in the summer, and then it starts to stack. Stack for a million or 2 years = Greenland. Stack for 40+ million years = Antarctica. Ice ages like North American Ice Age end when the land moves outside of the 600 miles to a pole barrier.

Greenland and Antarctica are ice ages. Earth Climate Change is 99% about where land is. If Earth had two polar oceans, it would have no ice (much warmer). If Earth had two polar continents, two "Antarcticas" it would have roughly twice the ice, oceans would be lower, there would be a thinner atmosphere with less humidity, and it would be colder...


Earth climate change is about ice. Ice controls sea level, temperature, atmospheric thickness, and humidity.

Ice is about where land is. 90% on Antarctica, 7% on Greenland today.

Land moves.

Not that hard.

You're just another one-line Ding minus a few irrelevant smoke-and-mirror graphs.

A few? Smoke and mirror graphs? That's how you characterize the empirical climate EVIDENCE from the geologic record?

Is this a smoke and mirror graph too? Or is it the temperature record of the planet?

what's the problem? define it for us. Can't huh? you just pop and run without any significance. loser.

where's the problem in that? tell us, colors don't do anything for me. any day, describe what this says.

The warming trend began at the end of the little ice age.

Again... the current warming trend began ~400 years ago.

SO.....
the "$76 Trillion" TrollsterParrot posts daily has NO Current basis.
It's a 14 Year Old estimate!



Solar (and on-shore wind) has come Down in price 90%.

You must have dozens of examples where massive spending on wind and solar has reduced costs for consumers.

Post some.

They are doing so well carbon emissions are still climbing.

AI Overview

The last time Earth's atmosphere consistently reached CO2 levels of 400 ppm or higher was during the Pliocene Epoch, approximately 2.6 to 5.3 million years ago. At that time, the Earth was significantly warmer, with global average temperatures 2-3°C (3.6-5.4°F) above pre-industrial levels.
Sea levels were also much higher, potentially 15-25 meters above current levels.
