Fresh off the bench: a very cool pot base with classic Bell Beaker decoration, from last year’s excavation on our island shell middens.

@limpetnerd.eurosky.social - come for the Pokémon. Stay for Linnaeus, speciation and the conceptual issues that creating definite categories creates when applied to the messiness of the real world.
Also, hovering over a species opens a panel describing its relationships (XX pollinates YY and is eaten by ZZ).
There's a lot to be said about gen AI, but I definitely wouldn't have managed to do this on my free time, with my poor coding skills, and surely not in half an hour or so.
As an amateur naturalist, I listed the species found in my area and asked Claude to build a 3D model of the interactions between them. The ecosystem is nicely structured around the two large green balls (oak and beech).
It looks messy, but you can navigate through it and add taxa manually.

The sea surface temperature in the Bay of Brest with see a 10°C increase in just one week.
The usual summer temperature maximum is somewhere around 20 °C, and is normally reached in August.
One of the most studied coastal ecosystem in the world, turned into a hot marine stew.

Think of CO₂ removal like a time machine. How far back does planting 100 million trees take us?
One mature tree takes up ~25 kg of CO₂/year, so 100 million trees will take up 2.5 MtCO₂. That's a time machine that takes us back ~33 minutes in a year. Nature will not save us from fossil fuel CO₂.

Ep. 3 of “A Natural History of Limpets” is out!
Here I show how these animals are not just evolutionary marvels and biomechanical fortresses, but keystone species of rocky shores, and how they helped define the basic principles of ecology as a scientific field 👇
