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)

It's never really occurred to me that the US is quite unusual in having fleets of buses dedicated to getting kids to and from school. I wonder why that is?

Because yeah, here in the UK kids either go under their own steam, are dropped off by their parents, or take regular public transport (or a regular bus that's chartered for the school run twice a day).

Because us doesn't have public transit, and is pretty spread out, so walking isn't always feasible. A lot of people do drop kids off though, but it leads to huge traffic jams.

Why can they not just use the school buses to create a simple very basic bus based public transit system?

[–] JohnDClay@sh.itjust.works 1 points 2 months ago

Probably liability? And maybe they only pay the drivers part time? Plus, the school buses are absolutely the cheapest money can buy. The seats are too close together for adults to use, and they still might not have seatbelts?

Likely has to do with population density.
