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.

If it wasn’t per capita, we’d just be looking at population size graphs. It is useful information and shows what is possible. We should be looking at metrics like CO2 per unit of gdp also. It’s not just people, it’s industry. Some of chinas emissions are really other countries emissions, offshored for China to produce. China profits from it, of course.

I duno about that, largest countries in the world including EU:

Agreed, I've complained about Europes false green economy when it outsources manufacturing to China, including but not limited to

China was by far the largest supplier of solar panels, accounting for 98% of all imports

For a population as large as Europe it's disappointing their aren't more battery and solar panel manufacturers

The problem is that EU can't compete on price. However, as they are long term it is not as much of a risk to install foreign technology that is not necessary to internet connect.

The EU is reducing, which is why per capits is important. We can see what is possible. Clearly the USA is not doing well. China has made huge inroads in green energy and I think it's a combination of wanting to be at the forefront of new technology and a need for energy security.

As it stands, china is about triple the EU, while manufacturing for them. The USA is just burning carbon for no reason as they no longer manufacture. This will worsen until ai bubble pops. They have quite a bit of nuclear power though. Their oil based economy is just too ingrained. Similar to Saudi Arabia. Why bother reducing when oil is cheap.

I fully expect tariffs in carbon pricing to be the next trade tariff globally. Whyake the hard cuts that cost.more on your internal market when the competition does it cheaper and doesn't care about environmental effects. It forces incentives to do the right thing and prevents the externalization of costs.

There is a massive issue with adjusting for trade though. If you just imagine a country lets call it Green, which has no emissions, and a another country Black, which is fully run on dirty fossil fuels. Now when both countries trade, the Green country imports emissions and the Black ones are lowered. It can be that dirty processes have been outsourced to the Black country or you can just have the Green country do things better.

When you take the EU and China you can see both. There are absolutely dirty processes outsourced to China, but at the same time things like electricity are dirtier in China then in the EU.
