🌊With the Fall semester upon us, it's time to start thinking about recruiting/applying to grad school for 2026. If you are a marine scientist looking for a graduate student, I've created a form where you can add your name and other info: docs.google.com/forms/d/e/1F... Please share widely! (1/2)

In case you’ve never seen a data center, or their construction, here you go. This is Loudoun County, VA 🇺🇸. There are kilometers of these buildings. In the second photo, you can see several others- and so many more being built across northern VA. Q: How much energy do they consume? A: *YES.* All.

IT IS HAPPENING!!! I’ve been spent the past few years cultivating native plants around my property. The ecosystem responded 🥹 I’m up to: deer, foxes, increased bees/ butterflies/ insects, frogs, turtles, bats, rabbits, & hummingbirds/ increased songbirds (& raptors/owls). No black bears- yet.
