Climate - truthful information about climate, related activism and politics.

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)

Would it help that much on weekdays? It looks like peak loads are right about when the buses would be busy driving. But it would still be usefull for weekends I'd think.

Edit: looks like it changes quite a bit seasonally.

Evs are nice, but not a solution. Walkable bikable cities are the way we get out of this climate mess.

Electric buses are a positive though, as transit is still going to be needed.

What we should not be doing, though, is making laws that require EV buses instead of improving bus service in general.

Yeah. Good point.

I guess a thought I had is that instead of school busses, what if we used a public transit option for everyone? But then everyone would need to use it and we're not there.

School busses are def better than everyone driving their own students to school and back. So that was something I missed in my initial post.

Im just over the whole "ev revolution" but taking that out on busses is silly.

If you live where it's nice and warm year round sure. I personally have no interest in an eight mile commute to work in the snow and ice when it's below freezing for months.

Agree, but you'd need a lot more schools for that since currently they're too big right now to walk/bike to from all points within the district.
