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.

The silver lining right now is that teachers here are not forced to use the Prager material, and it’s currently being added as an option. I’m sure it’s just a matter of time before that changes though. It mostly comes off as virtue signaling for all of the dumb righties.

The real damage they’re doing right now though is the removal of gender and sexual orientation from everything. It’s rendering certain courses useless because they can no longer be approved to offer credit due to the removal of material that is pertinent to the subject.

Unfortunately, in Florida, "optional" with material like this means "a bunch of teachers will actually use it"

People will be surprised just how smart and dumb some people can be at the same time.

My "Magnetic Fields and waves" professor in a high end electrical engineering class. He knew his stuff, but would constantly go on about his love for Trump's brand of conservatism and would become aggressive to people in class if he suspected them of being either a democrat, a socialist or Muslim.

I imagine he is doing just well in Florida.

My astronomy professor was fired for being a massive anti-semite and general rightoid

Shoulda seen it coming when he talked about the possibility of forests on Mars based on his own comparison of satellite photography

I’d be curious to see how many teachers actually go through with it and start adopting it into their curriculums. I’m sure Florida is eventually going to use that as a metric to see how “indoctrinated” schools are.
