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.

To be fair, it will continue to worsen after we stop using fossil fuels for a few years since the effects "ramp up." So if this is bad now, we should really stop ASAP.

Yeah I feel like at the pace the earth works, we've pretty much guaranteed a couple of generations of misery even if we solve this today. It won't be solved today, not with the shit they have us fighting each other about. Meanwhile, Musk and Bezos saw Wall-E and have taken cues.

Also, we won't stop using fossil fuels. Not anytime soon, not early enough to stop the disaster ahead.

While I am of the camp that we will not stop using them any time soon due to their other uses (plastics, lubricants, synthetics, ect.) I strongly feel that we should stop burning them. There is no reason for the emission and GHGs to continue. Though I also wish we could put more effort into finding total fossil fuel replacement for the other uses as well.
