How do mesoscale eddies modulate CO2 fluxes in the Southern Ocean? Mesoscale eddies and Southern Ocean carbon sink The Southern Ocean takes up more than a quarter of the anthropogenic CO₂. Its powerful westerly winds, deep overturning circulation, and intense mixing ...

🌊🌀 Learn how mesoscale eddies modulate air–sea CO₂ exchange in the Southern Ocean.

🔍The key findings of a new 27-year high-resolution model study by Salinas-Matus et al. are summarized in this blog post: blogs.egu.eu/divisions/os...

Deep-sea mining discharge can disrupt midwater food webs - Nature Communications Deep-sea mining in the Clarion-Clipperton Zone may release waste into midwaters that support diverse marine life. This study finds such discharges could dilute key food particles and disrupt trophic l...

This study by my colleagues at University of Hawaiʻi at Mānoa shows that deep sea mining waste to be released near the ocean surface would disrupt marine food webs.

The same would be true of grinding and spreading rocks in the ocean for CO₂ removal. 🌊

Datasets and protocols for including anomalous freshwater from melting ice sheets in climate simulations Abstract. Anomalous freshwater fluxes from the Greenland and Antarctic ice sheets and ice shelves are impacting the surrounding oceans, and we need to be able to account for these effects in climate m...

Finally out! The outcome of a virtual workshop in Feb 2024 with modelers and observationalists to put together data and protocols to include historical changes in ice sheet/ice shelf discharge in CMIP models. Hopefully not too late for some CMIP7 runs!

How do mesoscale eddies in the Southern Ocean modulate CO2 fluxes?
Mariana Salinas-Matus, a PhD student in our group, took this complex problem apart in her newly accepted first paper. 🌊

How to fight climate change without the US: a guide to global action With the US government absent from the COP30 global climate summit, it will be up to others to avert catastrophe.

The US is not expected to send high-level representatives to COP30, and many say that’s for the best. Whether humanity bends the emissions curve sufficiently to escape the most dangerous climate impacts now depends on the actions of other big players

As part of the GCP-Regional Carbon Cycle Assessment and Processes-2, we recently published the Australasia's CH4 and N2O Budgets. The carbon budget was published in 2023, both papers, led by Yohanna Villalobos and a great team of collaborators.

New national climate plans have barely moved the needle on limiting global warming. Yet there is hope.

According to UNEP's latest #EmissionsGap Report, accelerated adoption of renewable energy and falling costs mean we have the tools to cut emissions now: www.unep.org/news-and-sto...

I've finally got around to curating a selection of films about the #climate crisis 🎥

There's lot of mediocre climate films out there, but for me these stand out head & shoulders above the rest 🎞️

They make excellent resources for classrooms, lecture halls, or community cinema's 🎬

What is an incel? “Involuntary celibates” or “incels” are major online spreaders of hate against women. Learn more about incel culture in this explainer.

💊 We found that the world’s largest incel forum has nearly doubled since 2022.

Incels' toxic ideology can radicalize young men & lead to real-world violence.

Applying this insight in a HE context:

"a process of ‘socially organized denial’ currently exists within unis, leading academics to experience a state of ‘double reality’ that inhibits feelings of accountability & agency, & this is self-reenforcing through the production of ‘pluralistic ignorance'

The #Klimaschutzverbesserungsgesetz includes concrete measures, such as 30 km/h speed limit, earlier shutdown of oil and gas heaters, full electrification of transport.
Together with the much needed climate protection, they go hand in hand with benefits for our health and life quality in #Hamburg.

Wie die Psychologie der Verdrängung nachhaltiges Verhalten behindert - die Wissens-Kolumne von Terra X und NANO Die Strategie der Verdrängung blockiert nachhaltiges Handeln. Der Extremwetterkongress verlangt hinzuschauen. Wie das - gesund - gelingen kann.

"Eine gesunde psychische Verarbeitung bedeutet immer auch, den eigenen Handlungsspielraum zu nutzen und auf unterschiedlichste Weise aktiv zu werden."

Deshalb mag ich konkrete Vorhaben wie den #Zukunftsentscheid. Wir alle können etwas tun. @leadohm.bsky.social

The drop in CO2 uptake on land (LULUCF) in Finland and Sweden isn't without political consequence.

Finland and Sweden now asking the EU for more flexibility. Norway has also made similar comments (but is not an EU member country).

Scientists have been fearlessly curious in uncovering the complexity of Earth system feedbacks. What they study now are the feedbacks of ecosystems' demise, exacerbated wildfires, glacier melting, permafrost thawing, changing AMOC, etc.
At times the fear becomes more powerful than curiosity.
