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.

TL;DR - CA needs more storage to better enable renewables growth, but otherwise the article is a bit of a solar hit piece.

The article muddies the waters by trying to connect cost savings in neighboring states who buy CA excess solar as "lost" revenue for CA ratepayers.

In some cases, negative prices do count as a small loss in the budgets, but generally, just because CA excess solar is cheaper than NM fossil fueled power does not mean anyone is "losing".

The article does mention Wall Street speculators profiting off of the energy market, which is a loss for ratepayers, but it's a problem with existing forecasting models, not solar. If utility modeling was better than Wall Street, there would be no profit for outside investors.

This is partially very helpful. Thank you.
