Towards the end of the last Ice Age, life as we know it almost blinked out of existence. The CO2 level was very low, and it is now climbing back to normal levels of about 7,000 PPM
During the Cretaceous period, atmospheric carbon dioxide levels rose to over 1,000 parts per million (ppm) compared to the pre-industrial average of 280 ppm. This increase in CO2 led to a significant rise in the greenhouse effect and elevated global temperatures
More like 700, but the dinos did fine with 1,000.

A lot higher.
“I knew NBC had been spewing chit for what seems like an eternity, but turns out they were around millions of years ago to measure CO2. Or their “experts” were.”
The CO2 meters 10,000,000 years ago were incredibly precise - and it’s so handy that they meticulously recorded their readings in a format that lasted to this day.
So where are the scientists telling us there will never be another ice age? Where are they?
The danger to the planet - and civilization - by the progressive left is MANY orders of magnitude greater than such posed by CO2 levels.
When will the media morons learn that ONE MILLION TIMES BIGGER Sun affects weather on Earth? The Sun has cycles of activity. and flares and magnetic storms. All that affects Puny Earth.
Al Gore was spotted inside Arctic circle using a hair dryer to reduce expanding ice.
Do these people really think I am so moronic as to believe someone can measure CO2 levels millions of years ago? Evidently half the country does. Makes me concerned about driving on the streets.
Exactly. Supposedly there were no humans....so it can get higher without humans.... Hmmmmm...
Only thing I see happening is plant life flourishing..the planet will probably burn up when a chunk of the sun breaks off and engulfs the earth...or a 5 mile wide asteroid hits a volcanic fault and spews billions of tons of C02 very quickly into the atmosphere...best thing, no AOC, no Greta and no “the view”. Comey will try and hype his next book by finding pebbles on the beach spelling out “ 86 EARTH..”.
More CO2 means more food crops.
We are in an interglacial period. There have been extensive glaciation in the past and there will be extended glaciation in the future. In such a period the atmosphere warms until it begins to cool approaching the new ice age.
Oh puh lease!!
Mars is the closest to a planetary experiment we have.
You are correct that the martian atmosphere is more than 90% CO2 but it also in absolute terms has 10 times the total amount of CO2 on earth. The martian atmosphere is dense enough to fly a helocopter drone so it isn’t a near vacuum.
If there were such a thing as a planetary greenhouse effect due to CO2 alone, we would see it on Mars but we don’t.
The surface heats up in the martian summer sun to 25 degrees C and cools right back down to below freezing at night.
More bullcrap.
CO2 ppm has risen from 425 parts per million to 430.
It was 5000 ppm during the era of dinosaurs, with a maximum of 9000 ppm. Tell me why the earth didn’t burn up back then. Tell me how the earth naturally reduced CO2 concentrations back down from 5000 ppm to 400 ppm.
They keep pushing the globull warming hoax. Less and less people are buying it now.
“CO2 levels record goes back how many years? 500 years? 1000 years?”
There is direct co2 samples from ice bubbles form Antarctica that are 2.7 million years old. The ice is dated with isotopes in the water and surrounding sediments it picks or that where blown into the ice before it was.buried that have a radioactive decay constant. Multiple isotopes so they overlap and agree. The level of co2 in ppm really are not up for debate certainly not with direct measurements from ice cores.
It’s bad form to try to argue against solid data. The real question is does a 200ppm or so from the 1800s to now make for a difference relative to what the solar output and more importantly the orbital cycles our planet does on regular basis.something like 12,000 and 40,000 years cycles.
You would be wrong we have direct ice bubbles from well over a million years, try 2.7. Don’t be that guy who makes the right look like scientific illiterates. There is data it’s not hard to find if you look for it.
The actual scientific debate for those of us with PhDs some plural or at the very least multiple post doc work and tenure is how much human influence out of 250 ppm on top of the 180ppm present at the end of the last ice age when the sun heated up.
2.7 million years for direct samples you can just put a probe into the bubbles and get a direct reading so simple a high school student could do it.
Yep 78% nitrogen, 21% oxygen, .9% Argon
