I’ve led over 20 expeditions to the open ocean, chasing how currents are changing as our climate warms, only to find the answer lies at the smallest, most chaotic scales. Eddies are reshaping even the mightiest currents and bringing more extremes to coastal seas. www.nature.com/articles/s41...

It’s thanks to satellite observations 🛰️ that we can see how the ocean varies and changes globally, and how these changes affect society. We’re now inviting abstracts for the OSTST session "Large Scale Ocean Circulation Variability and Change", Wiesbaden, Germany, 22-26 June. ostst.aviso.altimetry.fr

The worldview of sea surface temperatures really does put into perspective how extreme the anomalous warmth is off the coast of Ireland. It's the biggest & most intense marine heatwave on the planet, some >5°C above normal. Enhanced rainfall & hotter heatwaves a possible impact.

The NOAA science seminars continue tomorrow with a verrry relevant talk on "The Social Value of Forecasting Hurricanes" by Renato Molina. Unsurprisingly, he finds that public investments in hurricane forecasts pay for themselves many times over in reduced losses. Read: www.nber.org/papers/w32548
