Crisp clear spring sky

When I walked to work this morning the sun had just risen and it was cold, so I wore my jacket and mittens. But it turned out to be a warm, clear spring day, and my outerwear is overdone.

Just look at this cleanly blue sky, framed by local spring-ready trees:

This post's theme song is Ben Platt's "Better", which has been on a loop in my head all day. It is sad and angry and an emotional wreck of a breakup song, but the self-echoing refrain scratches a mental itch and is immensely satisfying to hear. (Plus there are tons of repeated lyrics and they follow standard rhyme patterns, so it's quick to memorize.)

April Fool's?

These posters mysteriously appeared on April 1 across campus.

They are expressing ... something ... stridently.

It's just not entirely clear what.
And there's no call to action, or url, or reference to a student group... The posters are handwritten in marker, mostly all-caps, on scrap paper. (At least, the pages I read were unrelated middle pages of math or biology articles.)

Is this an April Fool's joke? If so, ... what is the joke?

[Update April 2: posters still up, so reduce the probability estimation of "this is an April fool's joke".]

[Update April 3: found a poster with slightly more context.

Updated my weight for "this is a protest or other political movement" with some connection to climate activism.]


This post's theme word is ekistics (n), "the study of human settlements, drawing on such disciplines as city planning, architecture, sociology, etc." Climate scientists of the future will focus on ekistics as a subdiscipline.
