Given that 2020 lockdowns was about as massive behavior shift we could hope for in the West, yet seemingly had no impact[0], what's the alternative to these schemes? Is the rise mostly now Chinese manufacturing? [0] https://research.noaa.gov/Portals/0/easygalleryimages/1/864/co2_data_mlo.png https://research.noaa.gov/Portals/0/easygalleryimages/1/864/...

In how many places were the lockdowns more than 10% of the year?

The lockdowns were targeted to reduce person to person contacts; not to reduce emmisions. A simmilar amount of hardship targeted at reducing emmisions would be far more effective at reducing emmisions (and less effective at reducing the spread of viral respiratory diseases)

The rise - and continuous rise, even though anthropogenic CO₂-emissions went down substantially during the lockdowns in 2020 - is largely dependent on the oceans warming up and outgassing CO₂ [1]. Historical records from ice cores show that CO₂ concentration lags after temperature changes - the concentration goes up after the temperature has gone up, and goes down once the temperature has gone down [2, see fig. 3 (p.431) for the relation between CO₂ concentration and temperature]. As long as the temperature continues to go up, the CO₂ concentration will go up. Once the temperature has stopped rising the CO₂ concentration will stop rising with a lag of a few thousand years [2, p.433, The CO2 decrease lags the temperature decrease by several kyr and may be either steep (as at the end of interglacials 5.5 and 7.5) or more regular (at the end of interglacials 9.3 and 11.3)].
