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.

That NOAA projection made me question what "sea level" even means if "sea level rise" can vary so much regionally. The extreme high end of the range (Gulf coast) is 18". The extreme low end (Carribean) is 6": 12" difference over about 2500 miles.

I did a shallow dive into sea level and learned that a variety of factors go into the calculation of sea level. Those factors have enough regional variability to mean that sea level is, in fact, a regional phenomenon.

The best explanation I found comes from NASA: https://climate.nasa.gov/explore/ask-nasa-climate/2990/sea-level-101-what-determines-the-level-of-the-sea/
