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!

And that is with shit rail infrastructure. Guess what would happen if we'd actually invest in rails?

Edit: Removed comma

This is totally unrelated but we don't use that comma after 'Guess' in English. I'm reminded of it because I'm learning German and it's been very difficult for me to remember to put commas after "I think" etc.

Hell would freeze over, that's what would happen.
