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.

It works on high speed lines in Spain, where you’ve got Renfe, SNCF and Trenitalia all competing for business between Madrid and Barcelona. Also in Italy where Italo and Trenitalia compete head to head on a bunch of route. London/Paris isn’t that much different.

Three decades of having private operation in Britain for the whole train network only yielded higher prices and shittier service than the old public service.

Also every single one of the companies you listed there are public companies and that entire business model is only working because the State paid for the high speed infrastructure.

If you want to see what happens some years after the State stops pouring money into infrastructure, look at Britain again - the infrastructure is slowly decaying and trains are getting slower, with the exception of the whole Eurotunnel which is brand new, State paid, infrastructure.

Last and not least, 2 or 3 companies only caring about a handfull of high value routes is in no way form or shape sufficient competition to add up to a healthy competitive market (just look at how many airlines serve high value routes for reference of how real competition looks like and even there, there are barriers to entry - in the form of airport slots - that limit competition so it's far from perfect in terms of competition), not to mention tgat what you see in the main most profitable routes is most definitelly not something that you see in an entire network.

It works on the few profitable liaison. Without the secondary network that is still publically operated, I suspect those route would not be profitable.
