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.

Sltldr: "They're just throwing away money, planting trees in the desert for them to die."

The Great Green Wall is a top down, big government intervention that has little to no local buy-in and isn't sustainable without continued big government funding.

Not surprisingly, the funding has mostly dried up, and so has the land.

Washington will likely reach a high of 94F (34C) on the National Mall on Wednesday, while New York’s Central Park is set to reach 87F, the National Weather Service said. The heat will extend across much of the Mid-Atlantic and southeast with at least 165 daily records expected to be threatened or broken next week.

Emphasis mine.

Many blue states are rethinking ambitious strategies to cut emissions as they struggle with rising electricity costs and new hurdles for renewable energy.

The big problem is that rising electricity costs are caused by fossil fuel prices going up, and can be avoided with large-scale wind and solar deployment. The US federal government is working to make that hard; state governments don't need to go along, even if some politicians are trying to use it as an excuse to avoid deploying renewables.

Microsoft made 90% of all carbon removal purchases worldwide last year, according to data from the third-party industry monitor CDR.fyi. The company is generally cited as making somewhere between 79% to 90% of all historic carbon removal purchases.

Deforestation to produce biofuels means that you don't actually get the claimed emissions reduction

With global warming making people increasingly dependent on air conditioning, power failures from hurricanes followed by heat waves are creating increasingly hazardous risks to health.

Blamed in part on climate change, the threat of water ponding in your yard or your basement is growing, a Sun-Times/WBEZ investigation has found, putting health, homes at risk.

Lee Zeldin, the E.P.A. administrator, said the changes would help U.S. “energy dominance.” Environmentalists said they threaten drinking water.

A lot of activists tried to make this the first big piece of fossil fuels infrastructure that we said No to, in part because it had clear political power to stop it with single-person accountability to the President for being able to reject it.

Even in Germany, there are now regularly more deaths from heat waves than traffic deaths (and air pollution is another big killer whose effects are multiplied by heat waves)

Analysis of six extreme heatwaves found that when temperature and humidity were accounted for, all were potentially deadly for older people
