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.

Can't really defend against some backwards legislature passing a law that says, "you can only use coal stoves to heat your house" or something, but it seems like a rear guard action that's fighting a fundamental shift in how we generate energy. If renewables are cheaper, much of the world will just go with that, which is what will drive most of the transition.

It is definitely a rearguard action, but it is a big enough deal that it has the potential to slow decarbonization enough to push temperatures outside of the range where we're reasonably assured of a civilization-supporting planet.
