Climate - truthful information about climate, related activism and politics.

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 a fascinating topic. It's top of my mind too - we have had very reliable power historically (Colorado) but in the last year had a major preemptive wildfire shutdown and a few other shutdowns (whereas literally less than 5 minutes of outage the last decade). I also got rid of my gas service last year and fully electrified. I have solar, but was waiting until battery prices dropped before going that route. Figured I'd yolo in the meantime, but that assumption has me increasingly on edge. From a climate perspective, I do hate to see a renewed interest in gas but I get why. We need cheaper batteries and standardized V2H/V2G asap.
