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.

I'm probably missing something here but doesn't putting a price on carbon just introduce a cost that will be passed onto the consumer and allow unscrupulous companies to avoid decarbonisation by just paying credits? And while we're on the subject won't credits just become another traded commodity that will become sought after and then people will demand more of them because their value would inflate another bubble?

It is different from carbon credits. I don't think you get a rebate from not emitting. If the cost is passed onto the consumer when there are good alternatives with less carbon, they will be out-competed. One thing with few alternatives is transportation, which low-income households tend to spend more on.
