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 feel like there are a lot of systemic problems with the electrical grid in California that need to be addressed before projects like this happen.

As far as I can tell there has never been any sort of reckoning among management at California utilities for the decades of underinvestment and mismanagement.

PG&E literally went bankrupt because they didn't inspect a powerline, and the cast-iron hooks holding it up swung slowly back and forth over a century until they wore through, dropping a live powerline to the ground, sparking a fire, and causing towns to burn down.

Yeah so unless there was a complete overhaul that involved firing multiple layers of management maybe putting more load on the grid isn't the best idea.

The bankruptcy took out a big chunk of their executive team, and induced a huge investment in grid upgrades. So completely reasonable actually.
