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.

Incredibly based.

It helps that Spain has world-class trains and are continuously investing in expanding the network.

I'm so jealous. I wish the complete shitstain right-wingers that cancelled train investment in my country were fired. (out of a cannon into the sun)

As Spaniard I wouldn't go that far.. but yeah they are good. But not all of them ๐Ÿ˜… specially the shorter routes. Apart from some maintenance issues, It doesn't help that from time to time a line is down because they have stolen copper wires...

One tragic fact of life is that it doesn't really take that much to become world-class as far as trains go. The HSR network alone basically places you on the podium.

Depends on the age of your tracks, if you have old Victorian bridges etc or aging signal systems it can be very hard indeed.
