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.

"Gas accounts for 40% of California's grid. However, its use in April registered its lowest proportion in seven years."

Grid storage wouldn't be lithium ion, something like lithium phosphate would be better.

Step one, buy in bulk to get a price closer to $150/kwh

Step 2, use for much longer than 2000 cycles, lfp have much longer expected lifetimes, and since space/weight aren't a huger consideration, you can replace individual cells when they go bad.

Step 3, produce your own energy, if you have your own energy generation, you don't need to pay grid prices, and profit is much better.

Disclaimer, I am not an expert in this at all, but this is how I imagine it could make sense.
