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.

Grid batteries reach stunning new peak of 44 percent of evening demand in California, the world's fourth biggest economy by GDP (reneweconomy.com.au)

The fossil fuel economy is finished.

The only question is whether it manages to drag a lot of human civilization into it's grave

This is another view on what happened on Sunday in California. Batteries charged heavily throughout the day, soaking up the excess solar, approaching charging rates of 10 GW at times. In the evening, most of the output was centred on the early evening peak, but batteries supplied a significant share throughout the evening.

The biggest loser in this transition has been gas, with the share of battery storage staying at high levels throughout the evening peak. On Sunday, it stayed above 20 per cent of grid demand for almost four hours.

As Fulghum noted: “To put that kind of output during peak demand hours into perspective, it’s equivalent to the output from:

  • 15-20 combined-cycle gas plants
  • 6 Hoover dams
  • More than the all-time peak demand of Portugal or Greece.”
