I love the boardwalk at @audubon.org Corkscrew Swamp Sanctuary in SW Florida. Such a great way to experience a range of wetland habitats and to see wildlife close up

“Water for the mill, wine for the stomach”
Spotted in a cafe in Milan. A more whimsical and constructive Italian version of the old adage “whiskeys for drinking and waters for fighting”.

One of the most dramatic locations for a cafe I’ve ever seen (look at bottom of photo), just a few tables perched over the cliff above the Tanaro River (trib to Po) in Barbaresco, Piedmont, Italy. Photo from medieval tower that stands over the town).

I’ve been using images of the “vertical forest” towers in Milan in my power points for a long time. Nice to finally see them.

Monviso, the “Stone King” rises in the distance, vineyards of Barbaresco in foreground.
The Po, Italy’s longest river, starts at the base of Monviso. We’ll go visit some spots along the Po tomorrow.

First #WaterYear photo dedicated to water in the form of fog.
Italian word for fog is nebbia and here is a foggy vineyard of Nebbiolo grape near Barolo in the Langhe in Piedmont, Italy, so named because it’s harvested as fog becomes common in the region. Dramatically dreary and beautiful

NEW | The world has achieved nearly a tenfold increase in solar power in the ten years since the #ParisAgreement ☀️
Solar rose from providing 1% of global electricity in 2015 to 8.8% in the first half of 2025.
Emerging economies now lead this growth 📈
