grease floats.

when it flows in sewage and into our plants, it thickens as temps fall, separating in our settling tanks.

the churning water forms grease globs that build like snowballs, and operators remove them so they don’t clog the process.

listen. don’t pour grease down your drains.

Almost no STEM graduate of my acquaintance was taught basic concepts of labor supply and demand, empirical organizational dynamics, or recent economic history, making them enormously vulnerable in their professional lives. This is disciplinary arrogance but it serves external interests as well. 2/2

I've been really curious about this after looking at seasonal solar production differences in central-north Europe (have in laws there). West Poland, Berlin are at 52N. That's way more north than North Dakota. Basically way less solar production in winter! Need to think what makes sense for that

Weighing in against my better judgement but I remember buying butter for $6/lb in bed stuy in 2013. Basically a single ridiculously expensive keyfood. It's like what, $4 today at trader joes in San Diego? Was cheaper to do groceries in other neighborhoods.

Should also look at this paper estimating home insurance premiums, also normalized against total home payment. 25-33% of monthly payments on home insurance in some zip codes! bsky.app/profile/davi...
Keys & Mulder build dataset to study homeowners insurance using over 74 million premiums from 2014–2024 inferred from mortgage escrow payments. Premium increases are capitalized into home values, reducing home price growth by over $40,000 in the most exposed zip codes. www.nber.org/papers/w32579

Definitely not the driver this year but a fascinating paper I can’t wait to read.

While short term data is noisy, there's a long trend at work - the slowing of sunbird migration due to climate change, as this Fed paper shows: www.frbsf.org/wp-content/u...
