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.

Wind, solar, and storage, which have replaced their nuclear at this point:

It might have been better to roll those out first, and shut down nuclear second, but zero fossil fuels remains doable within a decade.

Rising costs of energy starting Feb 22 is the cause of the last huge dip. As a matter of fact, rising the price of energy and the ensuing economic slowdown is still the most effective way to to reduce GHG. Being frugal is the only way to reach 0 emissions in spite of whatever rosy paint one wants to put on green energy, housing renovation and other half-effective measures.
