I don't see how it would be possible to shoot straight up like that..
OK, here's a question for all you climate Freepers. How exactly does one measure global co2 and compare it to 800,000 past year levels?
They can get air bubbles trapped in ice cores. They can date the ice cores very very accurately. So they measure the carbon dioxide in a section of ice and then date the section to get the carbon dioxide in the air from x thousand years ago. that number varies over time.
Well just Damn! I will be mowing my grass more this summer - But hay - my Tomato crop may be a Record Harvest!
Man the lifeboats!!!!
Don’t you mean ICE BOATS?
It is called “settled science”. I’m sorry, but questions along the lines of scientific merit are not allowed.
I knew this was going to happen! LOL!
The plants are loving it, and the temperature has flat-lined for 17+ years at levels well below those of the Medieval Warm Period.
> How exactly does one measure global co2 and compare it to 800,000 past year levels?
I would imagine ice cores but then again how can you really determine the accuracy of something like that really?
The left will do and say whatever it takes to push the global warming for profit crap down our throats even if it means publishing false scientific report findings to every well progressive / liberal website online (which is exactly what they are probably doing because the left never verifies or confirms information that bolsters their cause for accuracy)
They measure it from the tailpipe of your F350 Super Duty Crew Cab Dually..

Ice cores.
But I still think it BS.
The earth moves in cycles. And man can do little to change that.
800,000 Years????? Unbelievable that they would think anyone believes this!
Every measurement has an uncertainty spread attached to it. I'm guessing that the uncertainty spread here is very high.
For example, suppose that the CO2 measurement for 400,000 years ago (!) was 50 ppm. And suppose the spread was plus or minus 20 ppm. Then the actual value could be as low as 30 ppm or as high as 70 ppm.
I'd put little stake in numbers such as those.
Later and later Spring the past 8 years or so, with trees just leafing out and oaks blooming-that used to happen the last week of February to the 2nd week of March. Temperatures down to near freezing tomorrow night, yeah I’m sure the heat from that CO2 will kill us all soon...
And who, exactly do these lunatics think “saved” the climate 800,000 years ago? Tribes of Homo Habilis or Australopithecus? They certainly didn’t die out, either, so I don’t think the sky is falling...
ftemperatures down to freezing tomorrow night
Ridiculous
OH NO OH NO WHAT’LL WE DO???? We’re all gonna die! Etc.
Assuming the 800k yr high is correct, doesn’t that simply show there is not a strong correlation between CO2 level and temperature? Surely there have been plenty of periods since 798,000 B.C. when it was lots warmer than it is now. Maybe the fact that there is a lot of CO2 in the atmosphere means only that there is a lot of CO2 in the atmosphere. Maybe when it gets warmer CO2 increases, but not as much as the increase from fossil fuel usage. Either way, CO2 doesn’t change the climate.
Urgency, the hallmark of police brutality.
All these imperatives are crypto dictatorial fascist statements, also know as communist.
They use ice core samples. However, I do not trust them. These are the same liberals that claimed suicide rates are 25 times that for gun owners versus non gun owners but they used 1 county in many years of data to find that 25 times when no other years or county data supported the data. That said, I suspect they found 1 CO2 sample somewhere on the planet, such as in a dirty city in China, and compared it to ice cores they knew to be lower and then came out with this ridiculous claim.
My thoughts exactly. Is Al Gore that old?
