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.

Industrial carbon capture is a climate strategy environmentalists love to hate. Those committed to its development are trying to win back allies they sorely need.

Well the only long term storage solution is effectively making blocks of coal. Which requires a bunch of energy via non-carbon sources.

The chemistry for carbon capture from the atmosphere is far less efficient than carbon capture at the source but turning off the sources is a much better solution.

That all being said, as long we as a society retains access to above an EROEI of 30, it is a viable option but below that; not a chance in hell.
