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.

No nation-state in my lifetime has taken the real and necessary steps to mitigate/slow it.

Tankies will crow about China, but the truth is that China adopted the happy motoring lifestyle after relying on bicycles for decades.

Unless you drastically reduce cars and airplanes and cargo ships, nothing will change. Unless we pretty much stop eating beef, nothing will change.

If you actually priced environmental damage into the cost of oil, literally no business would be profitable. Instead we even subsidize it. The result is the world we have now.

We will suck every drop of oil from the ground even as we are choking on the CO2
