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.

I was under the impression that basically every commercial weather station just copied the NWS's homework, which is a decidedly Republican arrangement: have the taxpayer foot the bill for the actual work while private interest reaps the benefits.

If the NWS goes away, they'll have to do their own meteorology. Maybe there's some way to spin some profit from that situation that I'm not degenerate enough to see yet, but it seems like it's against their own interests.

A private weather service would charge for API access to do research and can hide information that would cause embarrassment for the owner or their friends, such as climate change. Plus, weather is a funny thing in societies all over the world: of something unexpected happens anyone can just blame the random ess of weather. But if a forecast is buried and a tornado warning doesn't go out, the info for who made that decision is hidden too. The people who died to a tornado or flooding or weather event will get no justice to private negligence.

Private weather will also provide a long term block for detailed weather analysis and cause weather sciences to stumble, of not stop development entirely.

The right don't want scientists, they want technicians who adjust readouts.

It's similar in the UK. The UK has a public weather service (the Met Office) and there are also private services that use the data from the Met Office. The private services cut corners with their forecasting software and have lower-skilled forecasters, and as a result, provide measurably worse forecasts. If you're making life-and-limb decisions based on forecasts such as which roads to close due to ice, you'd better have access to the best possible forecasts that exist, otherwise people will die.
