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.

These school buses no longer belch pollution. They also give the grid a break. (www.motherjones.com)

School buses are primarily used twice per day, five days per week, and otherwise sit unused. The morning operation time (6-8am) is off-peak so it won't have much impact on the grid to lose some storage at that time, though the afternoon run (2-4pm) would be right in the middle of peak load time, so that might be an issue:

Probably the most sensible thing to do is have the bus batteries offset the school's own daytime power demand (when all the lights and climate control are operating) and then recharge during off-peak hours.
