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.

saved you a long read - it’s “sustainable aviation fuel.”

Yeah, you can produce that, in small quantities. Get rid of the need for fossil fuels for ground transport, and a big chunk of the corn and soy crops that are currently blended into gasoline and diesel respectively can be used as aviation fuel. It's not a bad way to do it.

While there are hungry people, we shouldn't be growing crops just to set fire to them

Bio fuels are definitely an issue in that regard (and if SAF becomes a thing it can rapidly spin out of control). However, so far the far bigger issue here is the meat industry. Go vegan, save lives, save rainforest.
