Reflected satellite signals unlock new insights into Arctic sea ice - Earth Online Research drawing on novel data from Spire Global has enabled the generation of Arctic-wide sea ice maps, marking a major step forward for detecting change with navigation signals.

Scientists have been exploring how GPS and Galileo reflected signals can help monitor sea ice, using innovative data from @spire.com.
A promising new way to observe our rapidly changing polar regions:

The Arctic overturning circulation: transformations, pathways and timescales Abstract. The Arctic is the northernmost terminus of the Atlantic Meridional Overturning Circulation and is an important source of the densest waters feeding its lower limb. However, relatively little...

Pour chaque dollar dépensé pour protéger la nature, 30 dollars financent sa destruction Un rapport, publié jeudi par le Programme des Nations unies pour le développement, rappelle l’importance de supprimer et de rediriger les investissements qui nuisent à l’environnement, dont dépendent la majorité des entreprises.

Early career researchers need proposal writing skills. Therefore a new way of teaching proposal writing was developed. It is now accessible to the research community.

By applying a tracking method to both climate models and satellite data, @davyclimate.bsky.social found that sea ice age is a more sensitive indicator of change than ice thickness or volume.

If you're interested in sea ice and how we can track its development, you may want to sign up for our 1-day seminar where we'll be talking about the breadth of ECVs for sea ice, new developments in tracking sea ice age, and the pitfalls and opportunities of climate model - observation comparisons.

🌡️ Not all hot nights are equal. We track “tropical nights” when temps never dip below 20 °C—but what if it’s already 20 °C at bedtime? I crunched ERA5 data for 5 European capitals. Let’s talk tropical 10 pm. 👇

Atlantification drives recent strengthening of the Arctic overturning circulation A less ice-covered Arctic shifts dense water formation northward, strengthening the Arctic Ocean overturning circulation.
