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.

The US just kicked billions into the manufacture of hydrogen via electrolysis, which works just fine off renewably-generated electricity. Hydrogen is the key ingredient in nitrate fertilizers that has been coming from fossil fuels, so we will have a path off of them for fertilizers.

Fossil fuels aren't necessary, they're just how people did things the first time. This means we can get off them as part of a managed transition and keep on feeding everybody.

Great article with a nuanced and well researched take. I abandoned my hope in a grave a long time ago, but perhaps when I see these changes actually happening within my lifetime it'll rise again like Jesus or Frankenstein.
