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.

When it’s done right, it’s amazing. The problem is that (here in the UK) it’s just terrible.

Example, going from London to Edinburgh

A flight takes 1h30m and costs £33 A train takes 4h26m and costs £178

Yes there are other monetary costs involved (driving to the airport, parking) and other time costs involved (you need to be at the airport 90 minutes early) but the headline price make a flight seem like much better value for time and money.

Trains are also often late or cancelled, this seems to happen much less with flights.

Until flights are taxed to hell people aren’t going change their habits.

That's interesting, because it's basically the opposite in the US. They're cheaper and more reliable. You can't buy a puddle jumper flight for less than $100, and trains are rarely delayed by much, if at all.

I road that train! 70 minutes late so I got a full refund.
