What’s the most important subject we learn in school?
For climate, it might be thermodynamics.
It’s needed to understand climate change, to understand how a heat pump works, to understand why stopping CO₂ emissions is easier than doing CO₂ removal (CDR), etc.

"most engines retain an average efficiency of about 18–20%"

At sufficiently low price, it’d make sense at scale & I don’t think thermodynamics tell us what future DAC will cost

figuring out why the pivot point was 1988… and then why HW so abruptly cancelled his promised “White House Effect” … is just as big as knowing there is a multi decadal ocean inertia… on the politics.

probability = 1 / total number of choices.
since there are two choices (either we pick stats or we don't), the odds are 1/2 or 50%.
This can degrade into deeply misunderstanding statistical metrics. Which is how Phycology got into so much trouble.
Modern physics, evolution by natural selection, and plate tectonics, were all developed without using inferential stats.
Leads to understand that efficiently powering a train or bus off overhead wires is better than hugely inefficient processes like creating hydrogen to power same.
Leads to understanding that trains and buses and bicycles+ are better than a car each.
