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.

Meh. Other nations will probably just tax US imports to make up for it.

That mostly results in US goods being more expensive, making (checks notes) the totally carbon neutral goods from China more affordable.

Not if we enact a broad carbon tax 🤗

If you look at carbon intensity of GDP, the US is actually below global average and Europe especially western Europe is at about half of it. https://ourworldindata.org/grapher/co2-intensity

That obviously makes it a bad tool to pay for carbon debt, as it hurts poorer countries.

A just global carbon taxation system would need to take into account historical emissions.

[–] MrMakabar@slrpnk.net 1 points 2 years ago

I would just go for a carbon tax, without historic emissions and a wealth tax to hit the people who are actually benefiting from historic emissions. Thats propably about as fair as it gets.

Why would US paying anyone for anything?

How about US makes oil companies pay the treasury?
