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.

Newsom is starting to look a whole fucking lot like controlled opposition, tbh. Theatrical (and sometimes, incidentally effective, but that doesn’t appear to be the root motivation) pushback on right wing stuff for the most part. And quiet acquiescence to a LOT of stuff that someone who actually gives a shit about lefty things would not tolerate.

I can already hear the vote blue no matter who people in 2027/8 calling me a Russian shill for pointing out he abandoned trans people the second it became politically expedient 🫠 Or if I’m really lucky, arguing with me over how abandoning trans people is actually necessary or not happening or whatever else.

That was definitely a red line for me, too. I gave him credit for being incredibly vocal about equal marriage in 2004, way ahead of other politicians, but something seems to have drastically changed and moved him to the right.
