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.

You're missing the point that trees will only sequester a limited amount of carbon, once.

Yeah, I'm all for planting more trees, that's always good. Calling me "anti tree" is just "I have no good argument so I'll just throw insults"

Trees used for materials are replaced by more trees. That's more than "once", and I spelled it out for you in that second paragraph already.

Anti-tree? Yeah, you literally seem to have a problem with the notion that specific varieties of tree are worth trying to save. You may not be anti-all-trees, but you've sure wasted some breath trash-talking a particularly useful type of tree.

I'm not going to dignify your lack of argument and ignoring my own arguments by specifically calling you anti-evergreen or some shit. Anti-tree it is.
