Two figures with projected man-made emissions, one for CO2 and the other for methane. The red dots are very close to the scenario lines marked "business-as-usual".

   I opened the first IPCC report, released in 1990, and copied their scenario graphs for CO2 and CH4 emissions.

   I marked the latest data with a red dot. Methane emissions in 2022 were 580 Mt and carbon dioxide emissions in 2023 were 40.7 GtCO2 (= 11.09 GtC).

   Whatever you think about the IPCC you must admit their business-as-usual calculations were pretty robust.
