How do strong tropical storms, such as hurricanes and typhoons, drive changes in CO2 fluxes between ocean and atmosphere?

Our simulation with a horizontal resolution of 5 km in the ocean and atmosphere allows representing such phenomena in the atmosphere and also mesoscale eddies in the ocean.

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!

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...

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. 🌊

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...

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. 🌊

Mir fällt auf, dass das Buch, das ich gerade im Zug lese, viele misstrauische Blicke auf sich zieht 👀Aber es liest sich gut.
Global Greenhouse Gas (GHG) emissions rise again in 2024, up 2.3%.

This is our collective progress, 10 years after the Paris Agreement.

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

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 🎬

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'

Klimaschutz auf lokaler Ebene ist der Weg zu Innovationen, mehr Lebensqualität und einem positiven Einfluss auf unsere Gesundheit.

Hamburg braucht dieses verbindliche Instrument zur Umsetzung konkreter Maßnahmen zum Klimaschutz.

Hamburger #Zukunftsentscheid am 12.10.
zukunftsentscheid-hamburg.de

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.

At the Referendum on 12 Oct, the residents of #Hamburg will decide on the Law for Better Climate Protection - a crucial stepping stone for our city to achieve climate-neutrality already by 2040. We need such binding platform for innovation in Hamburg!

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).

Women in leadership often face a double standard: assertiveness is "too aggressive," while showing empathy is "too soft."

In reality, women who lead with both compassion and determination challenge outdated stereotypes and pave the way for a more inclusive and effective leadership model.

One of the functions of conservation science in the current era is to act as witness and document specifically how, where and why biodiversity and the ecosystems that support us are being destroyed. This in itself is an act of resistance. 🌏
