That would be CO2, not shown here. We continue to set yearly records for CO2 pollution. 2024 was the highest emissions ever, beating 2023, which surpassed 2022 etc.
This isn't GHGs, they're talking about like smog and particulate pollution, Sulfur Dioxide is what primarily caused acid rain, CO is toxic.
We still won't peak GHG concentrations for a while, as that requires net zero emissions.
