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.

I hate to be a single issue voter but I really enjoy future generations still having a planet to live on.

Most scientists will agree that even stopping emissions isn't enough now. We need to capture and sink money in removing it. GHG effect will work with or without our emissions at this point.

Earth is perfectly habitable with 10 degrees warming. The problem is that the jump in temperatures is way to fast. So biomes can not shift quickly enough, which causes huge problems. So right now the most important thing to do is to limit that jump. If we do not go too much higher, then most areas humans currently live in will still be habitable.

That much warming will also significantly shrink the part of the planet within the human climate niche. Even if it happened a bit more slowly, we'd end up with a lot fewer people as a result

At the cost of trillions of animals including humans.
