    *** Concentrations of CO
    2 in the atmosphere were as high as 4,000 ppm during the Cambrian period about 500 million years ago, and as low as 180 ppm during the Quaternary glaciation of the last two million years.

    15 Jan 2025 Average annual atmospheric levels of carbon dioxide (CO₂) reached a record high of 424.61 ppm in 2024.

    So 4,000 ppm = Nothing to see here

    But 424.61 ppm is a record High ...and we are all going to die very soon !! ...confused.png




    In 1871, the estimated CO2 level in the atmosphere was approximately 287.9 parts per million (ppm).

    Must have been all that Man-made CO
