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.

Sorry, gonna hard disagree there.

The first off-ramp we had to get off of fossil fuels was nuclear energy. It wasn't the conservatives who blocked that exit.

If nuclear energy buildup in the 1990s had followed the trend of the 1970s and 1980s, we could have kept CO2 below 400 ppm.

The three groups who conspired against that decarbonization were: the coal lobby, anti-nuclear activists and labour unions (because coal unions were strong back then).

Only one of those groups were the rich conservatives.

Only delusional people thing the Democrats actually want to help them. They're all crooked, the Republicans are just more open about it.
