Until recently, the U.S. and China were positioned to benefit from the clean-energy revolution. China already dominates manufacturing of solar panels, batteries, and wind turbines, and controls much of the rare earth minerals required to produce those clean technologies. Historically, the U.S. has led in research, innovation, and software, though China has overtaken us in many of these areas, such as electric vehicles and patents.

Now, Trump is ceding the field entirely, which amounts to nothing short of unilateral disarmament. His tax cuts have gutted U.S. clean‑energy incentives. He has withheld financial support for renewable energy and used red tape to kill off existing projects. Meanwhile, China’s investments in green solutions continue.

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.
