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.

Agree with the article except for the very end. The catch-22 we're in is if we don't stop emissions (forget reduce, we need to cease it 100%) to slow climate change then we're not going to be able to even adapt, but if we actually go against the world machine of economic and other growth and stop emissions, that will kill us too since we're so dependent on it. What do you do when any result is bad? I guess the one that seems the least worse in the short run.

"Nothing" seems to be the consensus.

I wouldn't say that. The EU and US are both starting to cut emissions (modulo the big swings caused by COVID). It's more that the world doesn't look likely to drop emissions to zero soon enough to prevent some seriously major damage.
