Many thanks, but I also seen reports (not sure where now) that the fossil CO2 emissions are decreasing. This means that we then have a decreased sink capacity in our ecosystems, which is larger than the reduced emissions?

There's common conjecture that global anthropogenic emissions are in a plateau/peaking phase. Data at least shows a slowed rate of growth.There was a slight decline in emissions during the global pandemic. Ultimately, emissions need to drop 50% in about a decade for atmo levels to start a decline.
