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.

This is legit the picture they've got on their site trying to sell it.

I'm going to guess it ends up being an ASDA warehouse or something.

Edit: I forgot HS2 was supposed to stop right next to it, before it was cancelled. It might have been worth something then. But now it's just some coal dust polluted land. I'm guessing they're not going to be allowed to sell it for housing due to that.

Oh the HS2 think maybe could have done something good. Might have been worth removing tonnes of soil and replacing it with tonnes of soil.

Can't be remotely as valuable now. HS2 was such a cock up. I'm actually reading a book about railways. Fuck could the Victorians get stuff done. Pick and shovel, no messing.

Given HS2 has already cost more than most European countries spend doing entire network expansions I'm pretty sure it was a massive success for its intended purpose.

The UK does things like include railways stations in the project, European countries don't. Hence the large cost difference.

But it needs to be done. We still have lines that are 150 years old. It will be worth it.

Even the shinkansen was over budget and unpopular when being built. Now nobody would argue it wasn't amazing.

Yeh but its like an order of a magnitude of difference, we're spending more than its costing Italy to build a subway through rome which requires a full on archiological dig every 20 feet.
