Earth's atmosphere hasn't had this much CO2 in millions of years

Trees are gonna love it.

Thank you for the info. I never imagined something like that was possible.

All life will become bigger.
Giant humans and dragonflies with 2ft wingspans.
I will have to get new clothes and bigger bug swatter.

This article is straight out the back end of a Bull.

New data shows that CO2 levels have broken through 430 parts per million, an indication that human-caused global warming will continue to warp the environment.

These idiots don’t stop to ask “Why was it so high in the past?”, do they?

What made it so high then, and what lowered it?

Maybe the Earth is a ecological system that self-regulates?

Antarctica data? Meaningless.
There were no dinosaurs belching and farting there.

Comma vs period policeman here. It was more than 125 years ago.

Are we all dead as yet????

Also next to a forest that produces O2 that messes up the measurements when the wind blows the “wrong” way.

Dragonflies are ‘good’ bugs - they eat bad ones. Don’t swat them.

But hundreds of millions of years ago, we did have some as big as you suggest:

Good thing I stocked up on 12ga 3’ Goose ammo. Them giant dragonflies gonna be hurting. It’s the foot long locusts that worry me.

[GingisK]

Some organs within, for sure.

Will also need a bigger bug zapper.
Powered by 440 volts.

College sources say 6,000, but I have older sources that go much higher than that. At 10K PPM, it would still be a trace gas and cause an explosion in plant growth and Oxygen levels. I don’t think man can effect it one iota.

An arthropod with a two-foot wingspan might be a delicacy - like lobster.

[minnesota_bound]

You will eat ze bugs!

[MortMan]

Unfalsifiable. All evidence supports the hypothesis. None can contradict.

[Openurmind]

lol, yeah I was in a hurry... Had to get back to the Musk/Trump event arena... 125K before our current was the middle of the previous Interglacial. The Temp and CO2 both were higher than during our current Interglacial. Chart source NOAA Ice Core studies.

There is an abundance of people in the wrong places who won't listen to facts. Facts don't allow them to pursue their own agenda. With that sort of leadership, our civilization will be a blast for future archeologists to sift out of the dirt.

I’m just happy to hear that you haven’t gone Euroweenie with the period glyph.
