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.

People will propose pretty much anything because they don't want to see a rapid phase-out of fossil fuel use. The worse things are, the more out-there the things they propose get to be.

I'm fairly certain that there's not enough frozen water to completely submerge all land, if melted.

Haven't looked into estimates in about 10 years, but the estimates back then were just for significant lowlands being lost.

correct, the article saying we will lose coast population areas, which make up most of humanity. So we will need to move further inland. man island nations will be lost, Australia will also get an inland sea, Bangladesh will largely be lost, Netherlands will be gone, etc.
