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.

We're at the point that geo engineering is a must for our survival, thanks to politicians not caring and businesses caring only about their execs and share holders.

Having said that, if geo engineering is successful, it will be abused immediately to just continue polluting. Calling it now that politicians will spin this as a great thing, totally not so that their rich donors can continue to abuse the planet.

Also, in the beginning it won't be successful. It will fail as politicians won't allow the required investments and push for shortcuts and buddy buddy kickbacks from friendly companies,, overriding scienctists and engineers in the process. That will destroy loads of lives and even more of the environment. That will become a scandal, them the politicians will do a mea culpa, and continue the same shit on a lower level whilst everyone ignores that large corporations yet again fucked over the world for profit.

Engineers and scientists will then pick up from there and manage to do the impossible and little bu little, progress will be made. Loads of profits will be made too, that's always the main goal, but humanity still might be salvageable
