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 got me is initially folks were talking about how brutal the winter was and I was like. This is kinda what I would call typical before the 90's. Now granted the double tap and what we got after new year maybe would have made it a bit worse than normal even back then but yeah the wierd swings have never been normal. I get it though. Its kinda nice to have some warm weather but while its nice as an individual in a point in time its scary as eff when you think about what its supposed to be and how abnormal it is and how we 100% its an effect from climate change but there are folks who want to pretend it does not exist.
