Two bits of bad news about CO2CO2 Carbon dioxide (chemical formula CO2) is a chemical compound made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature. levels as measured at Mauna Loa. First up, they still continue to inexorably rise as they’ve done every since they were first monitored back in 1958. Second up, after the rate of change slowed from 3 ppmppm Parts Per Million per annum to ~2 ppm in Autumn 2022, it’s now started to increase again, and the 12 month average stands at 2.41 ppm as of November 2023. I wonder if they’ll ever come a day in what’s left of my lifetime when they’ll start to fall, I very much doubt it 😥
