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."

First of all grid scale batteries are 10x cheaper then you think they are at $300/kWh. Then they are competing with peaking gas power plants. those are inefficent, but can start up and shut down quickly. However the cost of those is at about $151–198/MWh. per kWh.. So you need 2000 charge cycles to break even. Batteries also last a lot longer then that up to 10,000 cycles under optimal conditions.
