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

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.

Earth’s atmosphere now has more carbon dioxide in it than it has in millions — and possibly tens of millions — of years, according to data released Thursday by the National Oceanic and Atmospheric Administration and scientists at the University of California San Diego.

For the first time, global average concentrations of carbon dioxide, a greenhouse gas emitted as a byproduct of burning fossil fuels, exceeded 430 parts per million (ppm) in May. The new readings were a record high and represented an increase of more than 3 ppm over last year.

The measurements indicate that countries are not doing enough to limit greenhouse gas emissions and reverse the steady buildup of C02, which climate scientists point to as the main culprit for global warming.

yes, OSHA actually did tests back when we maybe had real science. the 470 ppm concern me far less than the autopen

“Basis for original (SCP) IDLH: The chosen IDLH is based on the statements by ACGIH [1971] that a 30-minute exposure at 50,000 ppm produces signs of intoxication, and a few minutes of exposure at 70,000 ppm and 100,000 ppm produces unconsciousness [Flury and Zernik 1931]. AIHA [1971] reported that 100,000 ppm is the atmospheric concentration immediately dangerous to life. In addition, Hunter [1975] noted that exposure to 100,000 ppm for only a few minutes can cause loss of consciousness.”

So this means that the CO2 has been this high before.

So they are admitting that this planet HAS had these levels of CO2 in its recent history (M of years is recent history for a 4.5B year old planet)...

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.

This is an absolute outright lie period.

CO2 was much higher almost exactly 125.000 years ago before the last ice age.

Logging off all those trees that convert CO2 into O2.

Hey, no sweat, I plant trees, they absorb carbon dioxide and turn it into oxygen. I say plant more trees!

CO2 levels record goes back how many years? 500 years? 1000 years?

Earth is 4,500,000,000 years old. So we have data for 0.000222% of earth’s life.

As a career engineer I ignore any data less than 66%.

Auuuuuuugh!!!

It's skyrocketed from .0427% of the atmosphere to .0430% of the atmosphere!

Just one question, Chief. What is the rest of the atmosphere comprised of?

Here we see NBC’s chief scientist trying to extend that assertion to hundreds of millions of years.

considering the real danger is snowball earth because we’re in the middle of a record low cooling period — more CO2 can’t be a bad thing.

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

We need green hamasholes protesting on the slopes and crater edge of the offending volcanos.
