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.

Rooftop solar 'cannibalising' power prices as Australian generators pay to stay online - ABC News (www.abc.net.au)

  • Wholesale power prices are increasingly turning negative at times of high solar output
  • Observers say rooftop solar is "cannibalising" electricity prices and hitting large-scale solar hard
  • There are calls for storage and greater daytime demand to help soak up solar production

That's why the calls for storage should be in the form of rebates for solar and battery systems for residential houses, rather than the big battery tech they keep on suggesting we use. Wholesale prices won't go negative if solar users don't sell the power they generate, and the solar users can save money too by using the power we've stored when the prices go up.

It's a win-win, albeit with the major exception of those who don't have solar. Who won't be able to take advantage of negative prices and will probably be hung dry with higher bills (keep in mind they are already pretty high to begin with)

Commercial cost are significantly cheaper at grid scale storage and also covers renters not just the elite ….

Build 'em all. There will be winners eventually. Until then, let's try everything.
