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.

Almost reminds me of falling. There's that first first 1/8th of a second where you are just beginning to realize you are falling, and in the next 1/8th of a second you are gone and there is no coming back.

With been in a 5+ sigma event, ongoing, since what, like, June? July? In November, when we would expect the annual global low to occur, we were outside of 2 sigma from what we would expect for the annual global high. In other words, our expected annual low was higher than our expected annual high, by a lot.

Kind of makes you wonder if the 'hot model problem', isn't really a data issue not a model issue.
