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.

How are we supposed to do that though? We're talking about BP partnering with the Iraqi government to extract their oil reserves, which then hit the global market. I realize BP brings technology to the deal but it's not exactly rocket science. I'd love to see moratoriums around the world, but that's going to be a bunch of individual countries/jurisdictions making those decisions. Companies are legally required to maximize profit and that means maximizing extraction. Killing the capitalism and making BP a workers co-op probably gets us the same decision, based on the reticence of any workforce to abandon their livelihood.

Here in the US we're at record oil/gas production but half the country thinks we're killing the entire industry. Like I wish we were actually doing that, but instead we just have the IRA (which is great all things considered) but it's mostly industrial policy focused on mostly the right industries for once.

You could, for example, cap total importation & extraction at a national or regional level, and lower that cap each year.

I'm just having trouble imagining the sort of global cooperation required for something like this. It seems significantly more difficult than a carbon tax, which is practically impossible already.

Cap systems like this are about equivalent to carbon taxes in terms of difficulty in cooperating around, but give certainty about total emissions instead of about future prices. They're mostly not implemented because they make it clear that you need to actually decarbonize.
