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.

Yup, this was it for my wife and me too. We don’t use enough to make it worthwhile and I held out for next generation tech.

Well, with the tax rebates expiring, we’re getting them installed by end of year. It should take 9 years to break even, so not awful, and really it’s always sat just about there with our usage. But it’s insane that we aren’t funding this or chasing it harder. Having that much decentralized capacity, while surely difficult to plan for, adds priceless resilience.

Edited to add: added bonus, we’ll be less stingy with the AC in the summer! Only 108 today… this is fine.
