Since the start of satellite measurements in 1979, Arctic sea ice already lost half of its volume (annual average).
🚨 2025 observed the lowest #Arctic sea-ice extent AND the lowest sea-ice volume for their yearly average values. This comes as no surprise to me as the polar environment continues to change. The consequences are far-reaching.

The nature cure: how time outdoors transforms our memory, imagination and logic. Without engaging with natural environments, our brains cease to work well. Exposure to nature isn’t a luxury – it’s a necessity.

Aux Antilles, la prolifération des sargasses étouffe les mangroves et les herbiers marins, « rendant l’espace inhabitable »
Les premiers résultats de recherches menées par l’université des Antilles permettent de mieux cerner l’impact des algues brunes sur la faune et la flore de plusieurs écosystèmes cruciaux.

Yes, that was our conclusion.

The increase in net calcification was independent of the net calcification indicating that the mechanism was decreased dissolution in under saturated microenvironments.

Here is a link to our paper:

We developed elegant methods to detect the biological response.

This was the first time that I know of where the biological response to a chemical perturbation in the ocean was measured in the absence of artificial confinement.

In the latest carbon budget, we revised...
* up land-use change emissions
* up the ocean sink (now takes up 29% of total emissions)
* down the land sink (now takes up 21% of total emissions)
* the "budget imbalance" now has zero trend

What does this mean?

Humans have emitted 2750 gigatons of CO2 since the industrial revolution from burning fossil fuels and land use change. To put this in perspective, this is more than the (dry) mass of all living things on earth and everything humans have ever built combined:

Drilling a 200m sediment core from the bedrock beneath 500m of Antarctic ice is a complex process, so we've broken it down step-by-step in this explainer. From melting snow in our flubbers through to filling our core barrels, what we're attempting 700km from the nearest base is no mean feat!

Hydrogen does not directly warm the climate, but interacts with OH to extend the life of CH4.

"More hydrogen means fewer detergents [OH] in the atmosphere, causing methane to persist longer &, therefore, warm the climate longer"
