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.

One method of making electricity cleanly to address climate change has been quietly advancing and on Tuesday it hit a milestone.

A California utility is backing the largest new geothermal power development in the U.S. — 400 megawatts of clean electricity from the Earth’s heat — enough for some 400,000 homes.

Southern California Edison will purchase the electricity from Fervo Energy, a Houston-based geothermal company, Fervo announced.

The company is drilling up to 125 wells in southwest Utah.

Clean electricity like this reduces the need for traditional power plants that cause climate change. The boost could go a long way toward bringing down the cost of a new generation of geothermal energy, said Wilson Ricks, an energy systems researcher at Princeton University.

“If these purchases help to get this technology off the ground, it could be massively impactful for global decarbonization,” he said. Decarbonization refers to switching out things that produce carbon dioxide and methane, which cause the climate to change, in favor of machines and methods that don’t.

Today the world still relies mainly on fossil fuels for round-the-clock power. This new deal shows that clean power can meet a growing demand for electricity, said Sarah Jewett, vice president of strategy at Fervo.

Yep, there were, for example, a mayor in Jonzac who made geo thermal for the whole village sometimes in the eighties (IIRC), it still runs today and I think all heat is just free.
