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.

Even if it was straightforward and easy, the eventual outcome will be people assuming it is enough to offset the pollution that it will never keep up with and make people even less interested in getting companies to stop putting carbon into the atmosphere in the first place. Just like the whole 'carbon neutral' and 'recycle plastic' have been blatant lies that make people fine with more pollution and trash.

Agreed. Carbon capture is absolutely an important tech that we should deploy after the cheaper, better solutions of removing carbon from our economies. Carbon capture should be the final phase where we help the Earth heal the damage we've done after we stop doing the damage. We need to first implement those stop-doing-the-damage phases.
