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.

Yes and no. It is possible for someone earning 70k/year to emit below the average (let's also keep in mind that the goal is not to be below the average, but to be at 0 emissions/impact), but everything you can buy has a CO2/environment-cost related to it.

As soon as you spend more, you have a higher impact. Of course there are more and less impactful ways of consumption, so you do raise a good point, but we're not going to consume our way out of this misery.

A really nice book I shove down the throat of every single one of my friends who's not running away fast enough is The Day the World Stops Shopping, in case you have way too much time at hand ^^
