CO2 level highest in 23 million years

Wasn't HI suppose to be under water by today?....and New Orleans...and Guam.....and etc etc.....

.001% of the atmosphere's CO2 comes from man, mother nature produces 99% of the CO2

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.

Sadly California has been victimized by decades of forest management by the woke ignorant. This travesty has been exacerbated by arsonists enjoying their right to pursue happiness.

I know that woke believers disregard science. I mean they do believe that men can gestate and deliver babies. But, CO2, was and is the foundation of all life upon this mudball. Without it, there would be no plant life at all. Presumably no forest fires either. Is that the win you are looking for?

 

[Muhammed]

That would mean a luxurious plant life

Anyone who wants a greener Earth is happy about increased CO2 levels.

Old Rocks Wow! I wonder why these "studies" never hold China and India responsible for providing the majority of air and solid waste pollution?

Arsonists are a big problem.

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.

Then the temperature should be what it was 23 million years ago, right? But it's not. It's not even close. It was 4C hotter than today 23 million years ago. Looks like you just proved that CO2 does not drive the climate. Congratulations.

See?

By god, they surely are

LOL!! CO2 causes fires in CA and hurricanes in New Orleans.

Where's the science???

China CO2...it's just different!

Exactly. Like you can't catch Covid at a BLM riot.

Climate change will just get worse and as it gets worse look at the deniers to change their tunes. It will no longer be that anthropogenic climate change is fake, it will be it is real but there is nothing anybody can do about it.

Only an idiot can't see what is happening globally and argue this is normal

Of course it isn't.

The tens of millions, if not hundreds of millions of dollars that fossil fuel companies spent on climate change disinformation these past 50 years has paid off. Even those companies, like Exxon-Mobil that acknowledge the truth of climate change can not put the lie back into the bottle.

Take your beef to the world's largest polluter. Do you know who that is?

Let me understand this argument. Your position is that if the Chinese and the Indians want to destroy their environment we should do the same to ours?

The problem with shit like this is you don't know if the data is legitimate or not.

There have been numerous times when the climate research scientists have been caught red handed of either making up data or cherry picking data. They did it big time.

When science is funded then amazingly the scientists getting the money usually come up with what the funding source wants to hear and that has been delivered in spads with this Environmental Wacko scam.

Besides, there is no real proof that the CO2 that we see at this level is a source of global warming. There have been times when CO2 levels have been lower and the earth warmer and times when CO2 levels have been much higher but the earth cooler.

Then you have the fact that during most of the time the earth existed it has been warmer than now. On top of that we are in post glacial warming period that is a result of Nature.

Nothing except a silly ass correlation that says anything man made.

Nothing to see here boys and girls. Just more Environmental Wacko bullshit

If you're talking about GLOBAL warming, then it's all one environment, isn't it, dipshit?

So American CO2 is more dangerous that Chinese CO2.....hmmkay

We've reduced our CO2, China has increased theirs. Please chain yourself to their Embasdy in protest

You list what you deem is a problem? But what is your solution?

 

[AzogtheDefiler]

This is what leftists cannot comprehend

 

[JLW]

Hey dolt, the same argument applies.

You have made a toddler argument, in essence, that if little Mikey does it, little Suzie can do it to.

That is your argument. Were you sucking on a pacifier when you wrote your argument?

 

[JohnDB]

Ok...
Looking at the charts show correlation but not causation. CO² can come from forest fires as well as bacteria...

Man wasn't around 800,000 years ago. He didn't cause global warming then for sure.

And there also seemed to be temperature drops as well as CO² drops as well...

meaning that the temperature might be driving the CO² up and not the other way around.
