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.

Why this NASA climate scientist wants you to stay angry (grist.org)

Last month, climate scientist and author Kate Marvel resigned from her position at NASA’s Goddard Institute for Space Studies, where she had spent more than a decade studying a warming world. In her resignation letter, she cited the Trump administration’s attacks on the field.

“I anticipated that our work would be questioned,” she wrote, “but only because its implications were politically inconvenient. I never expected that science itself would come under attack.”

Marvel joins more than 10,000 professionals with doctoral degrees in the sciences who have left the federal workforce since President Trump took office in January 2025: a period that has seen the administration evict the Goddard Institute from its historic home on the Columbia University campus, dissolve the U.S. Global Change Research Program, dismiss the nearly 400 authors of the next National Climate Assessment, and repeal the legal foundation for federal regulation of greenhouse gases.

I don’t remember not being angry.
