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.

What this means in practice is that we enter a minefield where we start to lose major ecosystems as temperatures continue to rise.

This makes it incredibly important to do everything we can to limit the amount of additional warming we see; each 1/10 of a degree adds to the risk.

is destroying the planet still profitable? yes? then nothing will change.

Direct action is the only way. Make the status quo more expensive than doing the right thing.

it's not like we don't know who's personally responsible. it's like 10 fucking people. set their yachts on fire with them in it.
