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.

40 years ago, we had to worry about hurricanes occasionally, and you could usually count on a handful of powerful nor'easters each winter. Thunderstorms in the summer were frequent but rarely severe. We used to go out in the yard and watch the light show as they approached.

In the last 10 years or so, thunderstorms have turned into deluge events, and are starting sooner in the year. It's a coin flip whether a severe storm will be accompanied by a tornado watch/warning. My friends got lucky last spring, only sustaining minor porch damage while less than a hundred yards away dozens of trees were downed, some falling onto roofs. One of 12 tornadoes in the area that day. We've had double-digit tornado counts only 4 times in the past 70-some years, and three of them were in the past 5 years.

This is not normal.
