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.

As U.S. and E.U. Retreat on Climate, China Takes the Leadership Role (e360.yale.edu)

COP30 in Belém may well be remembered as the moment that the world accepted the leading role of China in addressing humanity’s most important challenge.

but now the E.U. is beset by internal problems. Its primary industrial economy, Germany, is suffering from Chinese competition, and with the rise of right-wing parties, resistance has emerged to the ambitious climate policies of the European Commission. One symptom of these internal troubles was the E.U.’s embarrassing failure to agree its own mitigation targets before the informal deadline of September 30.

The United States, meanwhile, is trying to force its partner countries to buy more U.S. oil and gas.

I wrote that recently in another thread, and it's true also here.

Your view is oversimplified to a degree that it is outright false.

However, it is not necessary to engage in such a discussion as it is not relevant here when we look at the data and how it is calculated.

According to the scientists at the Climate Action Tracker (CAT) cited in the linked report, China is behind by any metric, including by what the CAT scientists call a country's "fair share." This reflects the “common but differentiated responsibilities and respective capabilities, in the light of different national circumstances”, as stated in the Paris agreement (Article 4.3),

Here you can find China's CAT rating. As you can see, China's 'policy and actions against fair share' is rated as insufficient, with its overall rating highly insufficient.

As you can also see in the CAT rating, no country is on track, but China is among those countries most behind by any comparative standards.
