The Mediterranean is getting warmer, and marine heatwaves are a defining feature of that change. In 2024, it recorded its highest number of MHW days in two decades. Mean SSTs reached 1.23°C above the 1982–2024 baseline, rising at 0.32 ± 0.01°C per decade. eu-space.europa.eu/components/e...

Scusate la latitanza. Caldo. Considerando che la media delle temperature massime a fine agosto in Italia dovrebbe aggirarsi intorno ai 28-31 gradi e che la massima media a inizio ottobre dovrebbe oscillare intorno ai 21-24 gradi, possiamo simpaticamente dire tre cose: 1/5

This new tool, the Carbon Impacts Tracer, which translates carbon emissions into real-world climate impacts like heat exposure and coral bleaching, looks super useful. ➡️ carbonimpactstracer.com

New tool directly links carbon emissions to amount of environmental and economic damage caused
Carbon Impacts Tracer can be used to estimate climate impact from emissions across eight different factors, including lost food production

We do have problems if we don't clean them, but during our experiments we schedule regular cleaning both inside and outside the mesocosms. For the outside of the bags, our scientific divers take care of the onshore mesocosms (the ones in the photos, 3.5 m deep) and also the offshore ones (20 m).

Were the doses tested too high? We wondered that as well while deciding on this experiment. But a threshold only becomes visible once you exceed it, though, and close to a release site, before the addition dilutes, values like these can actually occur.

Carbon limitation under very low CO₂ is the most plausible explanation for the delayed bloom. But below the detected threshold, the community seems able to cope.

During the spring bloom, we raised alkalinity in our mesocosms by up to ∆TA +1250 µmol/kg. Up to ~+700 (pH <8.9): the diatom-dominated bloom proceeded as normal Beyond ~+900 (pH >9.0): it started 6–9 days late

There’s a lot of pessimism about mCDR, its role, whether it can ever be deployed at scale. I ask myself the same questions daily. But here’s our technical team 💥 putting our mesocosms in the water at 6am for the next OAE experiment. Only KOSMOS-GEOMAR has tools like these anywhere in the world
Pre-dawn dockside scene: three KOSMOS mesocosms — large transparent domed floating enclosures wrapped in protective covers — lined up on a quay, ready for deployment. A red hydraulic crane mounted on a truck stands ready to lift them, operated by a worker in a high-visibility orange jacket.

I think the way to read the UNEP report isn't "we'll miss the 1.5°C target so we need CDR to reach it", but "we'll miss the 1.5°C target, and we need to decarbonize ASAP because wherever we end up is where we will stay for a long time." www.unep.org/resources/li...

🧵CO₂ removal (CDR) is back in the news, but just because the UNEP report says we need CDR, it doesn't mean we'll have CDR. Many challenges will take decades of research and negotiation to solve. Here are some examples: Technological: We currently don't have any durable CDR method that scales.

Book #25 of 2026. Away for a while, so I had to bring my Kobo, and I usually struggle to read on it 😬 So I picked Liz Moore, a writer worth the hype. The “The Unseen World” is an incredible book. You can’t stop reading it Now I’ll miss Ada, David, Liston and all the rest. Highly recommended 📚💙

My GEOMAR group feels at home in Gran Canaria, first time for me. In a few days, we set up a mesocosm experiment on OAE (a type of mCDR). My role: impact on phytoplankton, base of the food web. I believe environmental impact will be a key factor in whether OAE can be deployed. Excited to be here

More trees are needed to cool down European cities in heatwaves – but they must be planted nearer to homes
Some European cities have poor tree shade cover and this is ramping up heat for their citizens.

3/3 More art for everyone (cheaper museums) and room for kids&teens too. Joy&voices were great; a museum isn’t a cemetery. But it isn’t an amusement park either. Some people want 20 quiet minutes in front of a painting and that’s beautiful too. We should go for the art, not just to say we were there

2/3 What I loved: a museum full of people from everywhere, all ages, all relating to art differently. But one thought: we should look at art (this is the real experience), not just photograph it, at least for a few minutes (I also took photos). The painting will still be there once the phone’s down.

1/3 Art consideration people might not care about. Yesterday I visited one of the most beautiful museums in the world: MoMA. Bit of context: I was a lucky kid: my parents took me to many art museums from when I was tiny, so I learned early how to approach (and how not to) an exhibition
