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.

My understanding is that post NEC 2023 tandem breakers will not meet code. Yes, you can still buy them and yes I could put them in without people knowing..but that's not the way I do upgrades. You can still buy quad breakers but I don't think those ever met code.

Thanks for the info. I likely could be fine with a 20a/240v circuit...but i don't even have that available currently. I'll do some more research on the tandem breakers.

Oh man, they are coming for our tandems too!? My area is still under NEC 2020 by ordinance, which is still more recent than a lot of surrounding counties. It's still recent enough to need GFCI on dual-pole breakers going to outlets, which was a real pain in terms of availability and cost.
