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.

There is nothing carbon neutral about cutting down trees, using energy to make them into pellets, putting those pellets on a diesel freighter to cross the ocean, and then setting them on fire.

They fear the lag between when the emissions escape from power plant chimneys and when new trees are able to absorb carbon will create a “carbon debt” which could accelerate the climate crisis in the near term

Exactly. Planting trees is the only thing that is positive in this equation.

Burning wood = more CO2

Cuting down trees = less carbon capture = more CO2 in the future

The only reduction happens at the place trees are planted and if that is in another country then you are not reducing your country's carbon footprint. And if the exporting country isnt planting trees than you might as well burn oil in regards to CO2 emissions.
