As a result of increasing emissions, the global atmospheric CO₂ concentration has increased by 50 per cent since pre-industrial times, rising from 277 ppm in 1750 to 416 ppm in June 2023.
The CO₂ concentration in the atmosphere today is much higher than the natural range of 172 to 300 ppm that existed for hundreds of thousands of years.
In fact, CO₂ concentrations now are likely to be the highest they have been in at least the past 2 million years.
It was estimated that 37.5 billion tonnes of CO2 were emitted by the end of 2022.

clearly you don't know about the physics of carbon dioxide and other greenhouse gases (GHG). CO2 has a long half life and so accumulates in the atmosphere.
