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.

It's pretty fucked up that there's so much useless shit that was produced to go into the landfill, but it's not just that; we're forced to buy plastic even if we don't want to. Most medication comes in plastic containers. A lot of the stuff that you buy at the store comes wrapped in plastic, even fruits and vegetables. Cars are mostly made out of plastic these days, and in a lot of places you're forced to have one in order to do practically anything. Shoes are usually made out of plastic. Junk mail oftentimes has plastic in it too. I want to not consume so much plastic, but how do I even start?
