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.

Can we just shit out a lot of sulphur dioxide (anti greenhouse gas) into the atmosphere for 50 years whilst co2 emissions are halted?

Technically possible, but it'd be a few centuries before the excess CO2 is gone and you have to shit out sulphur. Unless you do massive CO2 cartridge too to reduce that time. And that will depends on cutting CO2 emissions to near zero what doesn't seem to happen anytime soon. Plus you'd have everyone screaming how much it costs the entire way.
