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.

Scientists are warning that apparently stable glaciers in the Antarctic can "switch very rapidly" and lose large quantities of ice as a result of warmer oceans. (phys.org)

Don’t get carried away with this … I don’t mean for anyone to go out and kill people. What I’m saying is that the world won’t take any of this seriously until global climate change affects the world so much that thousands or millions of people start dying.

Climate change already has killed thousands of people. Starvation due to recent drought and people killed in floodings are examples of this.

But of course stupid people will just point out, that there have always been droughts and floodings and ignore the significant increase in such catastrophes.
