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.

It's an extreme exaggeration to say we will all die soon and that all hope is lost. Please do not fall into the doomer cesspit of despair, or attempt to spread it.

Yes, things are bad, but we're not out of the game yet. Renewable energies have gotten so cheap, even the capitalists can't resist adopting it for profit (as much as I hate capitalism, I do enjoy forcing them into making the right choices through profit).

We've just proven how effective geo-engineering is from the removal of sulfer from bunker fuel, and there are much cleaner ways to seed clouds on purpose to cool the planet and the oceans, which could give us more time for those juicy profitable renewables to fully take hold, slowing our descent into disaster.

Remember, once we've successfully switched to renewables, the fossil fuel industry will never be able to reverse it.
