Climate - truthful information about climate, related activism and politics.

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.

My takeaways are that more news exposure is good (see the availability heuristic and mere-exposure effect) for putting climate change concern on the agenda, while information campaigns aren't very useful unless they're paired with avenues for action. Policy changes (incentives and disincentives, regulations, price changes, social norms) can help with action.

Eh I'm still on team BOE is going to be soon. You do you though.

I only linked that page as it was a good explanation of the BOE, before today I hadn't looked at the rest of the blog.

And tbh, panicking about climate collapse, collecting and organising huge amounts of data on it, and then getting blasè about the upcoming genocide, is a very justifiable reaction. So while I'm no longer going to be linking that page on the BOE (as I haven't got the mental engery to fact check the rest of the blog), I'm not holding it against the author (provided they're not shilling disinformation propaganda that is).

an interesting comment on reddit, BOE before the end of the century, maybe sooner. CarbonBrief seems to indicate as soon as 2032... well... :)
