The catch:

Besieged by logging, fires, and pests, this global balancing act might not last long.

This is understated. I live in Canada and the pest danger is already severe. Every dead tree you see in the forests has the telltale squiggly track marks of the Emerald Ash Borer or other bark beetles. Out west is suffering record fires. Logging is the only category I'd be less concerned about here because they are required by law to replace what they harvest.

The health of the forests may actually be at least partially related to how they are replaced. The ecosystems of clear-cut replacement are starkly different than old growth, because you end up with all the trees being the same age. You don't get the rolling growth churn and resulting undergrowth.

Still strictly better than not replacing them, but it's still an imperfect system.

This isn't as bad as it sounds. In a way it mimics the natural reset normal forest fires cause.

No, because after a forest fire you don't get the "optimal full growth spacing" that planters are required to plant. You get plenty of gaps and crowding after a forest fire which creates the opportunities for the churning I described. If you look at a freshly replanted area vs a burnt out area 3 years later they're incredibly dissimilar even to someone with an untrained eye.

I didn't say it was perfectly identical. Ofc it isn't. Floor growth is almost all still there. It is good enough considering cutting is limited to specific locations only, and the alternative is to delete a primary industry.

Alternative planting patterns WOULD better mimic post-fire growth. No need to jump to the conclusion that the two competing ideas are do exactly what we do now or abolish a primary industry.

Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world.  About 1C of total warming.  Second chart:  about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability.  Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases.  About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
