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.

Distinct regions are seeing repeated heat waves so extreme, they cannot be explained by climate models.

the 10 hottest yearly average temperatures have occurred in the past decade.

better wording of this would be the 10 hottest years recorded are the last 10. Soon to be 11.

I'm not sure that heat clusters over 65 years means the clusters will stay the same in the future. Going back 65 years, obfuscates the global warming acceleration that occurred since 1980, and perhaps 1998 or 2010 or 2015. At any rate, clusters would develop from a completely random process.
