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.

Living more simply sounds good when you're a American in your suburban house with giant car you think about how your quality of life could be just as good in a small apartment in a walkable city.

Living more simply is not as appealing if you're in a slum in India or Indonesia or a farmer in rural China and you barely have enough to eat as it is.

We who have rich lives should consume less, just as a moral obligation. But it's not feasible to tell the whole world to consume less, because the vast majority of the world consumes far less per capita than the developed West, and their standard of living sucks, and they want more stuff. And quite honestly they deserve it.

On an individual level I understand the appeal of simplification and using less. But it's not an effective solution to global climate change. India and China and Nigeria and Indonesia and so on will not accept degrowth. Their choices are between sustainable development and unsustainable development. And so that's the choice the world faces.

Yes, but over consumption really is a first world problem, isn't it? If we ended consumerism as a norm more than 95% of the problem would disappear.
