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.

Kind of seems like a puff piece for China?

It really is not. China has built a lot of green tech in the last few years, but economic growth has meant energy consumption grew faster then renewables. However Chinas economy has problems, which China tries to solve by going green. So you get renewables and things like EVs actually replacing fossil fuels.

At the same time China is not a saint and per capita emissions are above those of most European countries right now.

Don't these emissions include the CO2 from the production of the imported goods those European countries consume?

Even if you adjust for that countries like France, Spain and Sweden have lower emissions. However the EU as a whole is 10% above China. Then again the data is from 2021 so they probably are about equal nowadays.
