Once China starts shutting down its old steel mills and coal plants, their emissions should drop drastically. That’s when USA will be left as the number 1 polluter in the world.

US is already #1 polluter per capita. China pollutes twice as much as US, but has over 4 times the population. Its quite incredible how little China pollutes already (considering how much or the world's goods they make). But obviously, I'm all for every country polluting less.

In recent decades, China has invested heavily on building renewable energy infrastructure. I think it's a matter of time until they start deploying arch furnaces, and grid energy storage. If/when that happens, Chinese emissions could be much lower than many other countries, no matter how you measure it.

People with more money than god would rather spend more time and money defending the use of a dead technology than ensuring another few generations of their descendents multiply their wealth into the sun by investing two cents into literally just modern technology, more at 11.

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.
