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.

  • 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

Hydrogen is hard and dangerous to store. Not only does it leak easily, it can also explode. You don't want hydrogen tanks in your neighborhood.

They already have cars storing and running on H2, so I don't think it's the problem it once was. See the Toyota Mirai.

Store it as a solid, no worries
