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.

They are further along their trajectory now. They were always heading this direction, that much should have been obvious to a lot of people all along. I believe it was, but that the endless propaganda of the US media machine kept most of its population from realizing it. There are all sorts of (arguably) respectable political issues conservatives of the past focussed their words on, while their actions spoke different.

Some of them might even have believed they wanted 'small government' or 'fiscal responsibility'. But their actions were clear in intent, from racial segregation, to the Red Scare, to suppressing social movements, to implementing a politic of austerity. I only fail to mention war because their liberal 'opposition' carries roughly equal blame for the US war machine.

The people today may be different in body, action, word, but this is a continuation of a long political project that ended up in facism.

oh there is definitely a trajectory. Pre/post nixon, reagan, and now trump it just gets worse and worse. At one time though they did have a level of reasonableness and could effectively work with others and share power
