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.

This image is wrong. 2016 was only 8 years ago. Yet our current temperature is well over +1C.

And I read somewhere that current ocean temps are more indicative of +3℃ of warming.

Like, most politicians are still f**king around like +1.5℃ is still decades off. We’ve already passed that point by most any reasonable, rational, and non-politically-farked standard.

Oh yeah. But what can you do? People prefer their comfort to the survival of their own children. Which is doubly worse because the boomer and X generation literally enslaved their own children, so, not only the newer generations will likely die out of famine, overheating, or violence from their own peers, but in the meanwhile they also have a terrible time.
