Looking at the top 20 (smartasset.com/data-studies...), I see three types of places: 1) big, wealthy outer suburbs 2) big, wealthy suburbs adjacent to a central city 3) medium-sized central cities. No low-cost digital nomad centers, interestingly. Great Trib article on the local economic impacts.

OK, as we go into February, I'm officially worried about our snowpack numbers across the Western US. Less snow means dryer soils and fuels heading into the summer and I don't like fire years where the high country comes online early.

In case we thought that ecological disasters were a special talent of modernity, let’s talk about how the 13th-century peat trade of Norfolk made it permanently vulnerable to flooding, including 3 catastrophic floods just since 2013.

#climaterisk transition risk!
New from @gruberte.bsky.social and I in @science.org: The energy transition is at risk, and energy models are missing the threat. Fossil energy networks from oil to coal to gas have minimum viable scales of operation, and those thresholds are closer than we think:

Sand is the most pirated resource.
My feed is dominated by sand discourse and it feels very nice.
Almost as nice as very fine sand, which (sometimes) squeaks when you walk on it.

I suppose it's a good moment to mention that the most neglected subdivision of sand is 'very fine' (63-125 µm)
so many people, including some sedimentologists, will just completely skip over 'very fine' and go from silt to 'fine' sand (125-250 µm)
don't forget about 'very fine' sand! 😁
