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.

We're scientists. We know the climate's changing. And we know why. (www.theclimatebrink.com)

A chain - including the logical type - is only as strong as its weakest link. e.g. if I compost a fantastic massage in ym bread (sic x4), but autocorrect mangles it all to hell, then what message did I end up conveying (regardless of what I may have intended)?

As a global society, it is starting to look like we failed. We did not consider the fundamentals as being important, so we were vulnerable to take-over, both from without and even more from within. Those who obstinately refuse to learn from history are doomed forever to repeat it.

The world will go on though, with or without any particular nation, or even species (i.e. us).
