Today, the emperor penguin has moved from Near Threatened to Endangered on the @sscmarine.bsky.social IUCN Red List of Threatened Species.

🛰️ Satellite images suggest that the population declined by 10% between 2009 and 2018 alone, equating to more than 20,000 adult penguins.

The earth, as seen from the moon.

The earth, as seen from the moon.

We are tiny. A handful of humans were 238,000 miles away from home, looked back, and beheld the world. We all need to pause, and look at the earth, and see that it is good.

The new lunar flyby photos need to spur us to reconsider how small, fragile, and finite our world is. Let them serve as a catalyst for new efforts at world peace (or at least deescalation of war) and for the survival of our beautiful, wonderful world.

I am not one of those who believes that history repeats, but consider the following from Herodotus: the Oracle at Delphi told the fabulously wealthy King Croesus that if he invaded Persia he would "destroy a great empire." Croesus invaded and lost--the empire he destroyed was his own.

From the experimental class trenches. This week's advanced skill was focused on improving reading. Task read daily for 15 mins. Student reflection "Reading a physical book in a quiet space felt more like an escape than an assignment, especially since I got to pick any book I wanted."

60 undergraduate writing responses on the Columbian Exchange and food history. Some of them really are excellent, but my eyes are crossing.

Update from experimental class--students do NOT read directions. It is frustrating. But I have noticed a shift in my feedback away from mechanics towards talking more about the medieval world. So that's a win.

Because honestly, who chases pavements? On the other hand, chasing penguins has a long, deep history.

I might actually have a problem. I'm sitting in panera working and they are playing an Adele song that I admittedly have not heard because I'm a cultural heathen, and I REALLY thought the line was “should I give up or should I just keep chasing penguins”

And William Dampier may be the first written account of Galapagos penguins, from a 1684 visit on the ship "Buccaneer's Delight".

It's online. Trying an option where there are ca. 18000 points available, they only need 10,000 for an A, and everything is complete/incomplete. They get a lot of agency in determining which assignments they do when, and how to structure their time.

I have real sympathy for college students right now. It is so hard for me to focus on grading and class prep with *everything* right now. But onward we must, somehow.
