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.

Maybe EVs are not a comprehensive climate solution??

Public transport would be a much more effective and cheaper solution, but we're all looking at EVs because it means not having to change anything about the status quo.

Yes. Easy patch.

I mean, public transport is a fucking ton of money to start up, and anywhere outside an urban center it is not just a loss but almost a total loss due to distances.

I remember being in a meeting in grad school to discuss the school bus system as part of the student review of finances. We had a bus route that went to another town a good distance away, and it was nearly always empty or with like 2 people on it, so they basically said once the grant money is gone we will shut down this route. We can't afford to put good money into something expensive and isn't getting used.

I realize there is a lot about car culture feeding that, but it remains a massive obstacle. Switching from existing structures like parking etc to public transport? How? How fast? What do we do with that space? Who pays for it? I'm frustrated by the system but we can't just start from a blank slate, we have to work with it.

The fact that the remote/rural bus stops aren't being used is not a fault of public transportation itself. But rather, it's the fault of route design/planning.

Isn't route design/planning part of a public transportation system? And even if it weren't, it's still a real and valid issue that would need to be addressed. Even if the plan is just to force everyone into high-density housing against their will, you still have the last mile problem, just like cable and internet companies. Either the bus stops at every building (and is therefore too slow to be useful) or some people have to walk farther than others, which is fine for most of us, but disabled/elderly/injured people shouldn't be further disadvantaged as part of our transportation strategy.
