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

[jc456]

Oooops!


What about the earth as itself 'reecent] history 'model.'
Ooops.
`

What about it?

 

[abu afak]

So what's your point?

jc456 is just another one line Ding minus a few irrelevant smoke-and-mirror graphs.

The Last Time Earth had >400 ppm of Atmospheric CO2...​

...It cooled.

And when it cooled, CO2 levels dropped, didn't they. Why don't you see if you can find a span of time over which temperature and CO2 moved in opposite directions. That'd really make your name.

After it cooled yes. Lagging temperature by 800 to 1000 years. The mechanism is the solubility of CO2 in water versus temperature.

Why you would think CO2 lagging temperature by 800 to 1000 years is a sign of the atmosphere controlling the climate is beyond me. This is clearly a sign of the ocean controlling climate and atmospheric CO2 levels dropping in response to the climate change because the ocean was able to absorb more CO2 at lower temperatures.

It's almost as if you have no ability to think about this things outside of your unfounded dogmatic beliefs.

Sure, that would be after the industrial revolution when atmospheric CO2 levels became a function of CO2 emissions. They haven't really moved in opposite directions because the planet was still warming up naturally but the correlation was broken. Prior to that atmospheric CO2 was a function of temperature, lagging temperature by 800 to 1000 years.

Isn’t that a cycle? Hahaha

 

[ding]

I have no interest in that. I'm only interested in the truth.

You are only interested in politics.

The Last Time Earth had >600 ppm of Atmospheric CO2...​

After it cooled yes. Lagging temperature by 800 to 1000 years. The mechanism is the solubility of CO2 in water versus temperature.

No shit?

Why you would think CO2 lagging temperature by 800 to 1000 years is a sign of the atmosphere controlling the climate is beyond me.

The data show two different correlations between CO2 and temperature. You want to pretend that one of them doesn't really exist.

This is clearly a sign of the ocean controlling climate and atmospheric CO2 levels dropping in response to the climate change because the ocean was able to absorb more CO2 at lower temperatures.

The solubility of CO2 in water is inversely proportional to temperature. That was understood a lo-o-o-o-o-ng time ago.

It's almost as if you have no ability to think about this things outside of your unfounded dogmatic beliefs.

It's PRECISELY as if you have no ability to think, period.

If you can't type a coherent paragraph explaining your beliefs then I see no reason to respond to your criticism of my beliefs. I'll just keep repeating what I believe.

1. CO2 lagging temperature by 800 to 1000 years is a sign the atmosphere is NOT controlling the climate.
2. CO2 lagging temperature by 800 to 1000 years is a sign the ocean is controlling the climate.
3. CO2 levels dropping in response to a colder climate is because the ocean is absorbing CO2 which is what colder temperatures cause.
4. CO2 levels increasing in response to a warmer climate is because the ocean is releasing CO2 which is what warmer temperatures cause.
5. Prior to the industrial revolution CO2 was a function of temperature.
6. At some point in time after the industrial revolution CO2 became a function of man's CO2 emissions.
7. At no point can CO2 be seen as driving the planet's climate. That would be driven by how the ocean distributes heat across the planet. Specifically the Arctic.

Please try to state what you believe instead of worrying what I believe.

I think you are fraudulent.

Let's see the graph you've been using for these points. Let's see if it adds anything to the conversation.

Carbon dioxide (CO2) levels and temperatures have fluctuated over the last 50 million years, with periods of high CO2 levels and high temperatures, and periods of lower CO2 levels and lower temperatures:

• 54–48 million years ago
  During the Early Eocene period, CO2 levels were between 1,000–2,000 parts per million (ppm) and global temperatures were 9–14°C higher than today. This period was particularly warm at high latitudes, and scientists believe increased volcanic activity was a major cause of the high CO2 levels. Model simulations also support the idea that high CO2 concentrations helped maintain the high temperatures.
• 50 million years ago
  Some studies suggest that CO2 levels reached as high as 1,600 ppm and global temperatures were up to 12°C higher than today. This period was so warm that the poles had no ice, and sea levels were at least 60 meters higher than they are today.
• 34 million years ago
  CO2 levels had dropped enough that the Antarctic ice sheet began to develop. This was followed by a long-term decline in CO2 levels, during which the ancestors of many modern plants and animals evolved.

Temperature and CO2 both rose. What's wrong with you?
