The National Oceanic and Atmospheric Administration (NOAA) also said that the global surface average for carbon dioxide (CO2) last year was 412.5 parts per million (PPM), among the highest rates of increase ever documented since the federal agency started keeping records over six decades ago.

250-400ppm, Normal background concentration in outdoor ambient air. 400- 1,000ppm, Concentrations typical of occupied indoor spaces with good air 

The global average atmospheric carbon dioxide in 2019 was 409.8 parts per million (ppm for short), with a range of uncertainty of plus or minus 0.1 ppm. Carbon dioxide levels today are higher than at any point in at least the past 800,000 years. Data are reported as a dry air mole fraction defined as the number of molecules of carbon dioxide divided by the number of all molecules in air, including CO 2 itself, after water vapor has been removed. The mole fraction is expressed as parts per million (ppm). Example: 0.000400 is expressed as 400 ppm.

Ned, "if CO2 were to go over 2000 ppm today most of that ice would (eventually) be gone." Agreed. And I certainly am not questioning the role of solar irradiance. But the geological proof that ice once existed at our South Pole -- striated bedrock among other unmistakable features -- would still be there. CO2 and Past Climates.

Då var jorden i stabilitet utan övertemperatur. Däremot är 285 ppm en farlig nivå som gång på gång givit +2C övertemperatur. Vi kan dra en linje mellan dessa två punkter och dra ut den så långt att vi når 2 x 275 = 550 ppm. 2021-04-05 · Current [atmospheric] CO2 values are more than 100 ppm higher than at any time in the last one million years (and maybe higher than any time in the last 25 million years). This new record represents an increase of 85 ppm in the 55 years since David Keeling began making measurements at Mauna Loa. CO2 levels in the atmosphere today are NOT at record high levels. Carbon dioxide is such a small component of Earth’s atmosphere (380 parts per million or 0.038%) that it shows up on the chart below as only a thin line (shown at 2x actual thickness, just so you can see it!).
