Percentage of co2 in the atmosphere.

As of 2023, the CO2 level in the atmosphere is 46% higher than the level in 1800. I’ve seen this calculated as just over 1 trillion additional tonnes of CO2 now, versus in 1800. The “small” percentage measurement is over 2 trillion tonnes. One is a small number and the other is large. But they describe the same thing.The projection of 40.6 billion tonnes of CO2 emissions in 2022 is close to the 40.9 billion tonnes of CO2 noted in 2019, which is the highest annual total ever recorded.
