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.

Companies can sue governments for closing oilfields and mines – and the risk of huge damages is already stopping countries from passing green laws, ministers say


Edit: I just found a totally relevant article and thought of adding it here, instead of making a new post.

how Wall Street is making millions betting against green laws

Now, however, the sector has found a far larger playground: financing massive arbitration lawsuits launched by companies against governments, where claims can stretch to tens of billions of dollars.

These cases come under a little-known area of international law called investor-state dispute settlement (ISDS), which allows corporations to sue countries for actions that hurt their profits.

With litigation funders facing no risk of a counterclaim, and potential awards that now average more than $200m (£160m), legal experts warn that the system has become a “gambler’s nirvana” for hedge funds and specialist financiers.

A longer article about energy costs, especially heating, and climate adaptation efforts, and how right-wing parties are profiting from fake populism about cheap fossil energy needs.

A relevant snippet:

In times of extremely high living costs, carbon pricing not softened by support measures is of enormous social and political significance: those who can afford to renovate or install renewable energy sources will be less impacted, whereas those who are poor or renting will have to spend much more of their income on heating costs and will furthermore be unable to free themselves of the dependency on CO2. Across Europe, a dispute over carbon pricing has erupted.

“We are currently seeing attempts by the conservative and right-wing factions in the European Parliament as well as by member states and the business community to undo climate efforts,” says Green Party MEP Michael Bloss. “It would make sense to start working now on establishing programmes for the potential revenues so money can be paid out directly from 1 January 2026. Otherwise, there is a risk of the ETS2 becoming a social trap from 2027.”

...

According to Sibylle Braungardt from the Öko-Institut in Freiburg, there are large subsidy programmes in Germany for energy-efficient renovations and replacements of heating systems by more sustainable alternatives. However, it is mostly high-income households taking advantage of these programmes. “It’s problematic if homeowners can renovate and install heat pumps to pay their way out of carbon pricing but renters cannot.”

A closely watched civil trial that began in North Dakota last week could bankrupt Greenpeace and chill environmental activism as the climate crisis continues to deepen. The multimillion-dollar lawsuit by Energy Transfer, the oil corporation behind the Dakota Access Pipeline, claims Greenpeace organized the mass protests and encampment at Standing Rock between 2016 and 2017 aimed at stopping construction of the project. Although the uprising at Standing Rock was led by Indigenous water defenders, Energy Transfer is instead going after Greenpeace for $300 million in damages — an amount that could effectively shutter the group’s U.S. operations. “This case is not just an obvious and blatant erasure of Indigenous leadership, of Indigenous resistance,” says Deepa Padmanabha, a senior legal adviser for Greenpeace USA. “It is an attack on the broader movement and all of our First Amendment rights to free speech and peaceful protest.”

Because this is a common misunderstanding, they're talking about scope 3 emissions:

These are Scope 3 Category 11 emissions

That means it includes fuels these firms extract and sell to be burned by others, with much of the "demand" for it being induced by the fossil fuel firms, who explicitly have a cartel which drops prices whenever people start to move away from fossil fuels.
