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.

Summary:A Stanford professor has been posting on X about California energy for the past few weeks. During the midday peak solar for the past few weeks, over 100% California (assuming CAISO) energy was met by renewables.

This means nothing for consumers. Despite the low or even negative pricing wholesale, PG&E can still charge high amounts for this power. If we keep building and subsidizing solar, and no batteries, this power will need to be curtailed in spring and fall. So what is the news here - it should be a critical and engaging discussion about grid storage and stability. Or you know an article summarizing some tweets.
