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.

The fossil fuel industry runs a sprawling, lavishly funded operation spreading lies about the climate crisis. Pushing back against that disinformation needs to be a priority for the climate movement. (jacobin.com)

This is really it. We already have most of the technology and at a price point, where it is either already cheaper then fossil fuels or not that much more expensive. The more those technologies are adopted, the less fossil fuels are being sold. A lot of people underestimate how much money building pipelines, refineries, power plants, oil rigs and so forth costs. So pretty small changes in fossil fuel consumption can destroy the massive profit margin of those companies. Even worse once those structural changes are made, we are truly over peak fossil fuel. Obviously this has to be global, but just look at what happened with Covid and you can see the massive impact these changes can have for the fossil fuel industry.
