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.

Are climate models overestimating warming? please, God, make these arguments over whether models are too hot or too cold stop, I'm begging you (www.theclimatebrink.com)

Models blur the laymans picture and feeds into denial when predictions aren’t correct, and as their value lies in future predictions that past trends also corroborate, more emphasis should be put on said measureable effects.

No models, no chance of reliable forecasting. What the layman (or the oil-company shill) has to say about errors is irrelevant. All they have are baseless opinions and vested interests. Everyone who works on developing models is constantly bringing in new theory, responding to new kinds of observations as instrumentation and coverage improve, correcting the models based on observations, doing backcasting and improving skill scores.
