Helikite up, science on!
On board FOREL in South Greenland, the GreenFjord team deployed the helikite and carried out lake sampling, incubations, drones, and a science meeting — all framed by stunning views.

We’re thrilled to celebrate the latest work by our colleague Dominik Gräff! 🎉
Using seafloor fiber-optic sensing, his team watched Greenland’s glaciers calve in real time & found something surprising 🌊🧊

Depuis bien longtemps, la Berne fédérale se trompe sur la manière dont la Suisse est perçue aux Etats-Unis. Elle surestime sa position et ses leviers. Contrairement à d’autres pays, elle néglige l’importance du lobbyisme à Washington.
Et ça a commencé bien avant Trump.

Heat is a silent killer. The hottest June on record in Western Europe caused 2,300 deaths across 12 cities, of which 1,500 were down to the climate crisis (see link in comment).
Subsidizing fossil fuels costs lives.

The #Glacier Loss Day is reached in Switzerland!
From now on all melt that occurs on glaciers until October is unsustainable. This tipping point has only been reached so early in the record-shattering year 2022.
Expect big ice loss due to the prolonged melt season and feedbacks

Check out our new publication, led by Christel Hassler at @EPFL. In the Fe-limited Southern Ocean, most of the organic ligands that maintain Fe available for life are produced on site by phytoplankton and bacteria.

This paper shows that X (formerly Twitter) is a toxic platform managed to polarize views and promote toxic interactions.
Time to leave X! My next post will be to say goodbye and provide my new social media address in a non toxic, decentralized platform nature.com/articles/s41467-0…
