Doesn't look like GHG emissions are still accelerating: https://ourworldindata.org/co2-emissions
But 2021 was the biggest (full year) of emissions ever, more than covering the 2020 decrease. I don't know of any resources that track quarterly emissions, so I don't know if we can see whether 2022 is on-pace for another record year. Perhaps the price of oil reduced usage enough to reduce emissions this year compared to last, but I won't hold my breath.
GHG emissions are dropping year-over-year in developed nations, and developing nations will follow. https://www.macrotrends.net/countries/USA/united-states/carb...
In other words: you are both right.
2000 to 2020 seems like a steeper line upwards than 1980 to 1990, but yea, since 2011, it does seem we've rounded the corner.
I will adjust my belief. Thanks.
