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.

I've heard that back in the day when rivers where polluted as hell, there was this simple idea that made it into policy: an industry must draw water downstream from where they dump their liquid waste. If they wanted clean water, they had to filter it before releasing it back into the river.

Could a simple rule like this be enforced: if an industry is to dump anything into the atmosphere, they must intake any air consumed from that same spot.

Applying this to ICE cars would stall the engine. When applied to the cabin, it would kill the passengers. Diluting it into the air only postpones the problem. This "externality" has come due and it's expensive. Best to cut losses and stop pouring exhaust fumes into the air.

@albertcardona @silence7 @neanderthal It seems that most of our current problems could be solved by "internalising" externalities.

When externalities in beef production in the US get internalized into the cost to consumers, meat will become unaffordable, the whole industry would collapse. Likely a good thing.

Consider subsidies to oil exploration, oil production, oil transportation, corn, corn processing, and tax cuts to all of these.
