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.

The Saudi delegation has flatly opposed any language in a deal that would even mention fossil fuels — the oil, gas and coal that, when burned, create emissions that are dangerously heating the planet. Saudi negotiators have also objected to a provision, endorsed by at least 118 countries, aimed at tripling global renewable energy capacity by 2030.

Saudi Arabia has had an active delegation at every IPCC meeting over three decades - no excuse to be unaware, they always manage to scrape as close as possible to rejection from the process. By the way we misrepresent by saying "Saudi Arabia" - petro-dollars are only existential for an autocratic government (similar applies to gas-putin) - Arabian population would benefit from less climate change (their region will approach uninhabitable in summer - pity COP was not in July - note how they moved world-cup).
