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 propane industry’s weird obsession with school buses, explained (www.vox.com)

the propane industry sees an opportunity to seize a share of the auto sector. Its representatives are working hard to convince public officials to switch to propane-fueled school buses, which they claim are “near-zero emissions” vehicles that are better for kids and the climate.

Except — that’s not true. Propane is still a polluting fuel: While it is refined differently than diesel and natural gas and combusted in uniquely styled engines, it still has a measurable impact on air quality and the climate. If PERC’s deceptive marketing to children, parents, and school administrators is successful, the propane industry threatens to lock in fossil fuels and their polluting emissions for another generation of schoolchildren.

Still a bus! Yeah I can see why that might be better as a school bus.
