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.

A major US state just achieved a critical milestone for nearly two weeks: 'It's wild that this isn't getting more news coverage' (www.thecooldown.com)

A bit disappointing, was hoping for a bigger milestone but this is still a positive.

Relevant Text:

California has set a benchmark for renewable energy, with wind, solar, and hydro providing 100% of the state's energy demand for 25 out of the last 32 days (and counting).

Added context is that it isn't for the full day, only needs to be part of the day (ex. 15 minutes), where renewables provided all of the electricity needs for the state.

The article said “.25 - 6 hr per day”. I interpreted that to mean 1/4 of the day (6 hours). While not as good as 24 hours, it is definitely not a paltry 15 minutes.

To add on to what NegativeInf said and linked, "0.25" is a weird way to say a quarter of a day. It makes more sense, to me, that the zero at the front was left off and it should read "0.25-6 hr per day".

Yeah, I agree; my brain went off into left field I guess.
