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.

Often wondered what it would take to flood our home, just doesn't seem possible. It's Florida, it's flat, water runs out every which way. The house is almost at the top of the neighborhood, one street is a little higher.

Most of the land around here has 2-3" topsoil and under that, sand all the way to China. Even when we dry up, it's not like other soils where the top turns hard. Only the paper-thin top layer needs soaked, and again, sand forever.

Looked at a NOAA flood map, we're not even close, despite the local creek. It would have to rise several meters, several meters across a broad area. There's nothing to focus water flow around here. Also, we're nowhere near worrying about storm surge from a hurricane.

Am I overconfident? Only thing I sweat is tornadoes, spontaneous or those spawned by hurricanes. Even then, this house's structure is well above code for the area.
