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.

One day humans will look back on living next to roads with ICE vehicles similar to how we look back on people throwing shit buckets out their front window.

Oh yeah, if we survive into the future, at some point, the people of today will be looked at with similar contempt to how we look at the Romans sharing communal sponges on sticks to wipe their asses, how we see human/animal sacrifices, Roman use of lead, the very recent use of lead that put large amounts of it in the atmosphere for everyone to breathe, recent use of asbestos, doctors prescribing cigarettes or leeches going back a bit farther.

Except we're also leaving lasting effects that will also make some of them hate us like the hate some of us feel for the people who killed the dodo to extiction, or the catholic church for destroying so much of ancient American cultural records because none of it featured their religious BS (or creating a system that protected the priests that fucked kids), or the attrocities happening today. All the plastics, micro and macro, that will be everywhere, the long term and runaway climate effects, the lost biodiversity that will take millions of years to return (assuming we don't cross any major turning points that might slow it even more or outright stop it).

Good stuff, except for dissing leeches. They have a valid place in modern medicine, even if it was a rocky road getting here. Same with maggots.

Just don't look up.
