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.

Carbon capture is like geo-engineering in the sense that we should definitely be researching it, but we should definitely not be talking about it in the political space because there are much more effective solutions that are cheaper and can be implemented now. Carbon capture is only worth talking about doing once we've radically altered our economy to no longer produce carbon emissions and are ready to undo the carbon we've already pumped into the atmosphere.

Yeah. Currently, there's also no consensus that carbon capture or geo-engineering are even reasonably feasible solutions. They are still very much in the experimental stage.

Assuming we will invent a technological solution sometime in the future, instead of reducing emissions now is irresponsible and an excuse for inaction.
