*** Concentrations of CO2 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 424.61ppm 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 !! ...
In 1871, the estimated CO2 level in the atmosphere was approximately 287.9 parts per million (ppm).
Try...Hot ...High Winds ... Oh Dear ... Must have been all that Man-made CO2
