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.

Austria and France banned short-haul flights to boost train travel and reduce emissions. Did it work? (climatetrace.org)

So jealous of the countries that have kept train systems in place

It is a bit of hit or miss in some parts.

Valencia-Madrid? Very fast and good, even with a low cost operator.

Valencia-Barcelona? Not as good, but it still beats the plane.

Valencia-Málaga? You mean Valencia-Madrid-Málaga, plane makes much more sense.

Valencia-Badajoz? Again through Madrid.

Madrid-Badajoz? Fuck you.

When I did this I just rented a car. That's it's own kind of hassle but I think it still beat flying.
