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.

Yep. Conspiracy theories are deflections. Usually they're meant to turn the bad things the system does to them into mere corruption rather than an inherent effect of the system as it is. They are meant to escape the conclusion that the only just behavior is to become a radical lefist with all the social, financial, political, practical, and violent consequences that entails.

It's easier to say chemtrails are a conspiracy than that industrial pollution and climate change are inherent to capitalist democracy. It's easier to say that migration is an ethnic replacement conspiracy than that sabotaging the collective bargaining power of the working class by breaking cultural cohesion is inherent to capitalist democracy. It's easier to say that 9/11 was an inside job than that an antagonistic colonial-exploitative relationship with the rest of the world that inspires retaliatory violence is inherent to capitalist democracy.

If you make fun of a conspiracy theory, or get concerned about them believing the conspiracy theory, or in any way give attention to the conspiracy theory rather than the scary thing it obfuscates, the conspiracy theory is doing its job and earning its rent in their mind.
