CO2 level highest in 23 million years

[ding]

LOL Still repeating that stupid lie. Your bunch has been predicting a big cooldown for years. So here we are in a La Nina, and it is very warm. In fact, this year will probably be in the top ten for warmth.

How do you know CO2 is responsible for this?

 

[MadChemist]

According to this study, it appears that the present CO2 level is the highest it has been since the Miocene.

Abstract​

Current atmospheric CO2 concentration is known to be higher than it has been during the past ∼800 k.y. of Earth history, based on direct measurement of CO2 within ice cores. A comparison to the more ancient past is complicated by a deficit of CO2 proxies that may be applied across very long spans of geologic time. Here, we present a new CO2 record across the past 23 m.y. of Earth history based on the δ13C value of terrestrial C3 plant remains, using a method applicable to the entire ∼400 m.y. history of C3 photosynthesis on land. Across the past 23 m.y., CO2 likely ranged between ∼230 ppmv and 350 ppmv (68% confidence interval: ∼170–540 ppm). CO2 was found to be highest during the early and middle Miocene and likely below present-day levels during the middle Pliocene (84th percentile: ∼400 ppmv). These data suggest present-day CO2 (412 ppmv) exceeds the highest levels that Earth experienced at least since the Miocene, further highlighting the present-day disruption of long-established CO2 trends within Earth’s atmosphere.

Yay !!!!!!

When uneducated slobs sit around and pretend they have outsmarted the global scientific community? Definitely.

Out smarted them?...who have I out smarted?...the scientists that agree with you or me???....there are a growing number of climate experts that are saying C02 is a misplaced environmental concern....
Just because someone goes against what you have been fed doesn't mean they are wrong...maybe its you that is wrong.....

Crick told him, Mammoth agreed. They have concensus!

Maybe this will solve the problem of excess oxygen?

How to solve the problem of excess oxygen?

Oxygen concentration over 20% in the air becomes toxic and poisons the body. This means that on the plain, people live at the maximum permissible concentration. Those who live in mountainous areas are at less risk, there is an oxygen content of about 15%. What will happen if the concentration...

[rupol2000]

carbon is the basis of life, we breathe in oxygen and breathe out oxygen with carbon, it turns out that oxygen is drawing life out of us

The above picture shows temperature leading the CO² levels...not the other way around.

Rocks can't read

Another the sky is falling thread. Thanks for the laughs.

Climate change is good, otherwise we'd still be in the Ice Age. No fun in that

This graph usually shuts up the stupid Environmental wackos. That is if they were smart enough to shut up when presented with real data, which most of them aren't.

This guy understand why the AGW "data" is screwed up.

It isn't hard to do...it's quite easy to outsmart them...they graduated from the same lousy schools that the people handling covid graduated from....and its not so much that they are not smart...they are greedy and self absorbed...they government says jump and they ask how high....we have a very robotic science community....and that's no good for anyone....

Until you can address post #70, you are the uneducated slob.

It's the highest in 23 Billion years! in 23 giga-years!

Wheeze Awl gunna dyeeeeeeeeeeeeeeeeeeeeeeeeeee

 

[ding]

Nope.

 

[Crick]

Nope.

Current CO2 level is 420 ppm and, just FYI, a graph with time on one axis labeled "before BP" means - officially - "before 1950". Global CO2 in 1950 was about 315 ppm.

And we are seeing over a million acres of that luxurious plant life glowing at night in California. And dozens more fires in the Western States. Lots of luxurious plant life lying around on the East Coast right now. Wonderful, isn't it.

Mostly due to mis-management of forest lands and allowing excess fuel accumulation during past few decades. Regular regulated logging and underbrush clearing would have prevented a lot of this burning waste of timber resources.

Hmmm ...

Last I knew, the age of the Universe was pegged at around 13.5 billion years.

Some longer timeline perspective ...

It was 380 ppm at the time this plot was prepared but the point was that 23 million years ago atmospheric CO2 was closer to 600 ppm.
