So, there are three permanent trends behind the increased emissions, the direction of which cannot be changed. Therefore, emissions from forests are likely to continue to increase.

This is a good practical example of the fact that biological carbon stocks are only temporary, and therefore their inclusion in the national net zero targets cannot be scientifically justified.

Thanks for this explanation. How do changing rates of annual forest harvest fit into this? Has there also been an uptick in forest harvest (which would lead to more emissions w potentially mixed effects on removals due to regrowth vs old growth rates) in recent years? Or are harvests not increasing?

The harvest rate increased until the peak year 2018. After that, the harvests have decreased and the tree carbon sink has increased. So the the increase of emissions during the recent years is really about soils only.

With sufficient, diverse biological carbon stocks, they support each other, and store carbon longer. If one part of the stocks is removed, eg wetlands, or tree trunks, or leaves and small branches, the system may collapse. A chair with only 3 legs is not stable if it had 4 in the first place..

This seems inevitable from preservation of mass. There must be a limit of tons of plant biomass per square kilometer and there's nowhere else for the carbon to go.
