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.

Meanwhile in North America, Canada's VIA is operating on a shoestring and being further threatened ... and in the last 50 years the US has pulled up most of the rails that were installed in the previous century. We're stuck with airplanes, hybrid metro-transit, and what's left of Greyhound. But, hey, we've got a world to police!

Pointing to this whenever the conservatives in Sweden say we need to raise prices and hire more ticket cops in order to increase ridership

How does that logic make any sense? You need less barriers for rides hip, not more.

You're telling me.

The argument that they make is that more ticket sales -> more funding -> better service -> more riders

But honestly they spent so much on enforcement, it eroded the funding argument, and having to pay for €100 tickets every month, paying increased fines, and pass through slow ticket gates erodes the better service argument.

I guess that makes a little sense, but public transport should be an expense, not a business.
