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.

A second Trump administration would most likely grant permits for fossil fuel drilling and pipelines basically anywhere it has the say-so, scrap the methane fee on oil and gas producers and dismantle new pollution limits on cars, trucks and power plants. It would almost certainly revoke California’s waiver to approve higher standards under the Clean Air Act, seek repeal of the Antiquities Act used to protect endangered landscapes and attempt to gut the Endangered Species Act.

But perhaps most ominously, a Trump presidency would impede Americans’ ability to find out what’s being done to them. Project 2025 proposes dismantling and privatizing parts of the National Oceanic and Atmospheric Administration, a federal agency that studies and monitors the climate, and using an executive order to “reshape” the Global Change Research Program, apparently to muddy its assessments of the pace of climate change and the potential impact. We would walk into this new dark era with a blindfold on.

The title kind of buries the lede. A second Trump presidency will deliberately accelerate climate disaster, and that brings many other kinds of disaster in its wake. Humanity and the planet cannot afford another Trump presidency.

Imagine supporting the dude who can singlehandedly bring your entire species closer to extinction
