For two consecutive days last week, the amount of carbon dioxide (CO2) in the earth's atmosphere exceeded 402 parts per million (ppm,) higher than at any time in at least the past 800,000 years, according to the U.S. National Oceanic and Atmospheric Administration.
Carbon dioxide levels tend to peak in May, which means that they are likely to rise even more. According to an article in Mashable, a news and tech website, the latest figures "put humans into uncharted territory."
Just last month, the UN Intergovernmental Panel on Climate Change released a damning report that illustrated the growing dangers of global warming. The panel focused on carbon dioxide emissions and warned about the dangers of inaction.

These are in the White Mountains, Calif.
14000 ft, dry and barren! Hard to imagine anything growing there.
Wouldn’t the number of people on the planet have something to do with it?
I’m no scientist but I did sleep in a Holiday Inn last night.
From what I have heard, after a few hundred years the ice core layers get paper thin from compression. After that they use techniques such as bouncing lasers off of dust particles, electrical conductivity and other techniques. Analyzing this data, unfortunately, involves a lot of subjectivity and assumptions.
Ok, Ya all know that's false...
But everyone on this board will attest that I am the queen of England.

Why?
Gee he looks bad, I guess he quite getting the facials after leaving office. 800,000 years, maybe he died and some bizarre alien took his body. That would explain the insanity of it all.
I’m surprised Gore hasn’t complained about the internet being transferred to UN/European control, he said ‘he invented the internet! I thought he would want it back.(sarc)
Hey, I'm not defending their data, they don't have any. All their stuff is propaganda based on manufactured "facts".
The question was: "How do you measure CO2 concentrations 800,000 years ago?"
That's likely how geologists would go about it.
He’s prepping for the asteroid landing to ensure it’s inhabitable before Earth is destroyed.
Quick! Quick! Send all of your money to the nearest faceless government agency! For the children!
Spot on.
Fair enough, sorry I misunderstood you........
If CO2 is THE cause of global warming, then how the hell did I have the worst winter here since the 1970’s?
You have to use proxies, like tree-ring data. You cannot, however, stitch recent thermometric data to ancient tree-ring data and say it's valid. That's how Michael Mann came up with his fraudulent "hockey stick graph."
The chart below shows that atmospheric CO2 levels have been vastly higher in geological time, and the world did not end.
Oh no we got caught watching Star Trek on the taxpayers dime! Quick look over there! Oldest trick in the book.
So THAT’S why Earth ended 800,000 years ago!
It would have been very idiosyncratic.
At these scales, it’s like saying it’s been the highest since yesterday.
During the Carboniferous Period, CO2 levels were 400 times what they are now.
