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.

Stardust Solutions says its tiny spheres can reflect the sun’s rays without harming people or the environment. Critics say private companies have no business altering Earth’s atmosphere.

Pretty much anything but discussing the real need to end fossil fuels

Every decade we can delay climate change takes immense pressure off ecosystems and human migration pressures, giving them time to adapt more gradually. If this could work safely and didn't take money and effort away from CO2 reduction, then it would be good even if it eventually comes to an end.

That said, the "if" is false. Like plastic recycling, geoengineering is a way for people to accept pollution by pretending it's preventable. The company in question isn't selling a solution, they are selling a greenwashing ad campaign. And the NYT is already participating in the ad campaign by publishing the article.
