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.

For regular products it is actually the remaining way per truck that accounts for the majority of their footprint. Kinda why I usually roll my eyes when people cry about dirty cargo ships, while likely driving their own personal car. There's so many areas that would be more important to tackle first.

The whole concept of using wood pellets is bonkers though. You're basically using land to grow trees to burn them, which is stupidly inefficient and certainly not sustainable. It's pretty much a form of greenwashing, to give people the illusion of climate neutral energy production (similar to things like bio & e-fuels).
