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.

You didn’t read the article.

They’re calling for more research into geoengineering. They just don’t want governments going off half-cocked with under-researched “solutions” that might make things much worse.

Governments should also allow academics to investigate the possibilities of geoengineering, chiefly in the form of solar radiation management, which involves attempting to reduce the amount of sunlight striking the Earth’s surface, for instance through whitening clouds to be more reflective, or setting up mirrors in space.

What they’re arguing against is the kinds of solutions fossil fuel companies are pushing as a way to allow them to continue polluting. Fuck the scientists? These are the people trying to stop climate change.

“Geoengineering, like direct air capture, is a deeply uncertain techno-solution that fossil fuel executives love to push to take pressure off their core business of selling oil, gas, and coal, which, as more and more people are realizing, is causing rapid and irreversible destruction of our planet’s habitability,” he told the Guardian. “Fossil fuel elites will use geoengineering as an excuse to continue business-as-usual. As a climate scientist, my worst nightmare is continued fossil fuel expansion accompanied by solar geoengineering followed by termination shock. This would be game over for human civilization and much of life on Earth.
