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.

The move to trains in Europe seems great! But still it costs me ~£300 short notice, ~£100 otherwise per person to get from London to Paris by train so for any trips it'll still need to be planes unfortunately. I dream of a day I can make an affordable night time trip to the Mediterranean on a train

The pricing and general operations on the Eurostar are pretty crap, which also annoys me to no end since I also use it semi frequently. Thankfully from what I've heard the high speed trains in Spain don't suffer from the same issues.

Hopefully some competition will improve things. If this gets off the ground it can only be good for prices and service. https://www.euronews.com/travel/2023/10/12/evolyn-the-high-speed-rail-startup-with-mystery-investors-coming-for-eurostars-crown

This would be great, but won't happen as quickly as they say, and even if a competitor does get going, the lack of capacity at St Pancras is a major blocker to reducing the ticket price.
