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.

I note that federal nuclear safety regulations were just gutted

NRDC guy:

“No California utility or independent power producer has had the slightest interest in deploying more of a technology with that level of cost and operational inflexibility,” he said in an email. “This almost certainly won't change.”

Everything that I’ve seen demonstrates that Investor Owned Utilities absolutely love projects with high capital expenditures, because the CPUC lets them pass costs through to ratepayers with guaranteed profit margins.

Ratepayers continue to pay for San Onofre, which is slowly being disassembled after having been turned off over a decade ago due to engineering incompetence. There are no plans to move the 1400 tons of nuclear fuel waste that is stored on site - the unchanged, politically unsolvable, spent fuel problem being the original reason for California’s nuclear generation ban.
