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.

Spoiler:

I think the answer is community. We have to be responsible to more than ourselves. We have to feel an obligation to more than our children. It can’t just be a selfish desire to hold on to what we currently have. You can maybe grip tightly onto your comfort in the short term, but the more we resist being part of the collective solution, the less likely that collective solution is to happen. In a sense, you’re echoing a bit of this bunker mentality where we have these megawealthy people who are buying up land in New Zealand and wherever else trying to save themselves. That seems like such a sad way to see the world. Like, do you want to live in a bunker for a year eating canned rations? Is that the life we want to build? Or do we all try to make sure we have a world where there’s enough for everybody, where no one takes too much and we share what we have. I’d rather share.
