It's the Climate, stupid

To be fair, new oil is constantly forming. The only problem is it takes millions of years to form and hundreds to use, which leaves a bit of a shortfall in terms of energy supplies.

Sorry man but what's your point? I really hope it's not that oxygen was only 50% more than it is today whereas co2 was 500% therefore the co2 must have been responsible for their size, because that would be quite an embarrassing post for you.
Why embarrassing? Personally I'm not buying the CO2 hoax, but was just showing what the actually levels were at that time.You just wrote they didn't breath any CO2 like it was 0% in the air at the time.
Some people over here are thinking that the earth just exist for 800.000 years to show some graphs that goes back to 800.000 years.

You are welcome to shop at whatever store you please! Buy it or don't, CO2 is a well know greenhouse gas, but obviously not the only climate driver.

The "resolution" on the 800,000 yr time frame is excellent (actually went a couple 100,000 years back recently, with ice cores from Greenland est. 2,000,000 yr old), which is why it is used.

But here you go:

Study of ancient climate suggests future warming

The Early Eocene (roughly 48 million to 56 million years ago) was the warmest period of the past 66 million years. It began with the Paleocene-Eocene Thermal Maximum, which is known as the PETM, the most severe of several short, intensely warm events.

The Early Eocene was a time of elevated atmospheric carbon dioxide concentrations and surface temperatures at least 14 degrees Celsius (25 degrees Fahrenheit) warmer, on average, than today. Also, the difference between temperatures at the equator and the poles was much smaller. Geological evidence suggests that atmospheric carbon dioxide levels reached 1,000 parts per million in the Early Eocene, more than twice the present-day level of 412 ppm.

If nothing is done to limit carbon emissions from the burning of fossil fuels, CO2 levels could once again reach 1,000 ppm by the year 2100, according to climate scientists. The equilibrium climate sensitivity in CESM1.2 is near the upper end of that consensus range at 4.2 C (7.7 F).

The U-M-led study’s Early Eocene simulations exhibited increasing equilibrium climate sensitivity with warming, suggesting an Eocene sensitivity of more than 6.6 C (11.9 F), much greater than the present-day value.

Do high levels of CO2 in the past contradict the warming effect of CO2?

Almost half way to 1,000 ppm CO2

Hydroelectric dams will be shutting down in the USA, desert SW, more fossil fuels.

World War, more fossil fuels.

Van Life! More fossil fuels.

Wind Mills kill birds! More fossil fuel.

Birds aren't real! More make believe......................................................................

Everything we do alters nature. When nature is altered, things change. We effect the balance. You can’t write that off with water vapor.
7.5 billion peeps produce a lot of CO2, not to mention alla the other animals!

Prior to industrialization, the Earth's carbon cycle would have sequestered that.

We've fucked the carbon cycle by taking millions of years worth of sequestered carbon out of the earth and reinserting it into the atmosphere.

Ocean acidification is the real indicator of this.

We're all to blame, there's no excuses here, though, moving beyond cognitive dissonance is a real challenge for some.

Humans, incredibly amazing and tragically flawed.
