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 US no longer supports capping plastic production in UN treaty (grist.org)

Environmental advocates understand the announcement as a reversal, calling it “absolutely devastating.”

The Biden administration has backtracked from supporting a cap on plastic production as part of the United Nations’ global plastics treaty.

This represents a reversal of what the same groups were told at a similar briefing held in August, when Biden administration representatives raised hopes that the U.S. would join countries like Norway, Peru, and the United Kingdom in supporting limits on plastic production.

Nearly 70 countries, along with scientists and environmental groups, support the latter. They say it’s futile to mop up plastic litter while more and more of it keeps getting made.

Also only two comments mention plastic at all, which is odd given the topic.

It's so weird. It's like a mad libs that only comes up with one answer.

"US Government fucked something up again because of course they did."

"Let's n͟o͟t͟ ͟v͟o͟t͟e͟ ͟f͟o͟r͟ ͟D͟e͟m͟o͟c͟r͟a͟t͟s͟!"

Like yeah, Biden did some unexpectedly good stuff on the climate, and some standard Democrat stuff which definitely isn't great. This is part of the latter. I'm not even sure it matters, since Trump will be in charge of implementing this treaty so it was DOA anyway, but regardless of that: Did you guys forget the real life Nazis are going to be in charge in a couple of months? It's going to take a ton of work to even have elections in four years that we can not-vote-for-Democrats in, let alone some good progressive change to keep pushing the Democrats towards something resembling a decent environmental policy. Just not voting, and then sitting back all satisifed like "that oughta do it," is such a mind-boggling strategy... and yet it's the one that always gets consistent airplay.
