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.

What a headline.

China - for the first time - announced an emissions target, and it falls short according to practically all independent experts.

China’s new emissions reduction target, announced at a high-level climate summit at the United Nations in New York, has been judged by experts as “timid” and falling short of the effort needed to meet global climate goals, even though it represents an increase in the country’s climate ambition.

China could lead other countries while their effort being insufissant, no contradiction in the article

I'm not defending China, but this is all the countries in the world. There is no legal mechanism for everyone to achieve climate targets. Even if Trump never pulled out from Paris Climate deal, the deal itself is nonbinding. Nicaragua was right not to have initially signed it for that every same reason, because the deal will not punish anyone for not meeting climate targets. It is also unfortunate, but not maybe surprising, that the international climate funding became a money laundering, green washing scam because there is no oversight. Like, one construction of a hotel received financing from the fund because it has "green initiative". The funding became source of vanity projects and corruption.

I fully agree that practically no country is on track, but the title literally says, "China leads nations with climate plans". This is outright false.
