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.

And the odds of any of that actually happening? How exactly are you going to regulate the growth of industries internationally in a way that doesn't just end up offshoring the pollution to poor countries like it already has been for centuries?

Dudes right, we need a dues ex machina to save us. We won't make meaningful changes until it's profitable to do so. So expect to see a lot of companies transition into cooling and environmental control. Because they won't address the core problem, just sell you bandaids for the symptoms. The next advancement won't be "less emissions", it'll be "this new coolant cools 35% better".

Look at heat pumps. Its literally just an AC unit that can swap the hot and cold side with a valve. It's nothing new. But it's the new "miracle cure" to all your heating and cooling needs. Just run your electricity that most likely comes from a coal power plant and smugly think about how you personally aren't using gas to do it!

We won't fix it ourselves without major intervention.

Realistically, you couple domestic regulation with a carbon tariff, assessing incoming goods a fee based on differential pollution in their country of origin.

Ok. You did that. China is still selling to other countries and polluting all over the place.

Now what?

Somalia is still burning our recycling. What about that?

For every hole you plug, there are 10 more. But sure, we can call agree on this one thing even though the entire history of humanity has basically been "I disagree, let's fight a war over it".
