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.

This word was rejected by geologists. But it’s already taken over the world. A panel of scientists rejected the term “Anthropocene” — but others keep using it. (wapo.st)

As the shimmering blue haze of the alien reconstitution field dissipated, the ruins of Earth’s last data center flickered to life. The leader, Z’kar, watched as fragmented data streams danced across the screens. The final days of humanity were illuminated in a chaotic cascade of, what are now known as "memes", desperate pleas, and a strange acronym that pulsed through the digital ether: "FAFO." "F-A-F-O," Z’kar mused aloud, puzzled. "It seems to be a crucial concept in their final communications." The translation matrix whirred, delivering a rough interpretation: "Fucked Around and Found Out." The alien research crew exchanged glances, their scales shimmering in perplexity and intrigue. "It appears," Z’kar concluded, "that humans were issuing a dire warning. They experimented recklessly, and this was their way of acknowledging the catastrophic consequences." The team pondered the enigmatic human spirit, a mix of defiance and fatalism, now just echoes in the vast void they once called home.
