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.

Sustainable aviation fuel won't fix climate change, though. As long as the fuel is carbon based, CO2 will come out which fuels climate change

Electrical Aircraft are a BAD idea, no matter what muSSk says

We need to get electricity from renewable sources to use for industry, homes, and CO2 filters world wide, and likely let aircraft fly with carbon fuels, I don't see a viable alternative for that.

And on the carbon sequestration (CO2 filtering), please stop doing that now, it's not the right moment and quite literally only makes the problem worse. First get everything transitioned. Once that's done, then you can start sequestering and actually make a difference.
