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.

Why not both?

You'd absolutely need to do both, unless you wanted all sorts of malformed incentives.

Generally speaking, the revenue from a pigouvian tax needs to be spent mitigating the problem that generates the revenue. Otherwise, you end up with something of a Cobra Problem, wherein excess consumption is seen as a revenue driver that the state subtly promotes.

Isn’t this article about UK?

I'm just speaking from personal experience.

If you want to talk shit about the UK, you can always point to HS2. Cancelled out of spite by the outgoing Conservative government. Chronic mismanagement of the rail network has been a lead weight around the British economy for decades.
