New study from #CLICCS researcher Jakob Deutloff finds no strong evidence for a tipping point chain reaction from carbon-cycle elements like #permafrost or the #Amazon.
However, 9 of 16 tipping points could still be crossed under current policies.

⁉️ Has the German #coal phase-out really reduced #emissions? Only if EU allowances are deleted. Without coordination, effects may shift or even backfire.

🌍 🎨 How can art make climate change and science tangible?

With “Portraits of Climate”, scientists and artists explore this question together. The exhibition can be visited at the University Museum in Hamburg. Learn more and join Dr. Anna Pagnone for a virtual tour here: https://www.cliccs.uni-hamburg.de/press/dialogue/art-science/exhibition.html

Also don't miss guided tours through the exhibition at the "Long Night of Museums" on April 26! More information: https://www.langenachtdermuseen-hamburg.de/museen/universitaetsmuseum-hamburg

Encroaching seas are a constant threat along the coasts. Traditionally, houses in the Seychelles are therefore built on stilts. But in recent days, more and more responsibility is transferred to government, replacing many of the traditional practices and individual initiatives to improve resilience, reports climate adaptation expert Beate Ratter.

Wie kann Ethnografie die Forschung an globaler Umweltpolitik bereichern? Was bedeutet Klimagerechtigkeit eigentlich? Und wie können wir uns Hoffnung in Bezug auf den Klimawandel bewahren?

Solchen Fragen und mehr widmet sich die Veranstaltungsreihe „Ethnografie und Environmental Humanities“ der Universität Hamburg ab dem kommenden Donnerstag.

Zu allen Terminen und mehr Infos: https://www.kulturwissenschaften.uni-hamburg.de/ekw/ueber-das-institut/institutskolloquium.html

🌎 📣 „Hamburger Perspektiven zur Klimaforschung“- öffentliche Vorlesungsreihe startet morgen!
Jeweils Donnerstags um 18:15 berichten Forschende über unterschiedliche Aspekte der Klimaforschung. Mehr Informationen und alle Termine: https://www.zfw.uni-hamburg.de/oeffentliche-vortraege/programm-sose/01-hamburger-perspektive-zur-klimaforschung.html

🌊👩‍🔬 Girls' Day 2025

Heute durften wir im Rahmen des Girls‘ Day Mädchen am CEN und Institut für Meereskunde willkommen heißen. Mit Experimenten und Messungen am Eis-Tank konnten sie hautnah erfahren, was den Beruf einer Klimaforscherin ausmacht.

#GirlsDay #WomeninSTEM

Im aktuellen CEN Newsletter geht es darum, wie KI für bessere Sturmflut-Prognosen sorgt, welchen Preis eine Abschwächung der AMOC hätte und wie Tiden die CO2-Speicherung in den Meeren beeinflussen. Jetzt abonnieren und nie wieder etwas verpassen: https://www.cen.uni-hamburg.de/press/newsletter.html

🌴 The Coco de Mer is a botanical wonder, a case of "island gigantism." This palm species has separate male and female plants and is found only on the Seychelles, reaching heights of over 30 meters, #CLICCS geographer Beate Ratter reports.

❄️ A recent @CNN article by Laura Paddison features Prof. Dirk Notz from #CLICCS. Arctic temperatures are soaring, up to 20°C above normal, leading to the lowest February sea ice levels recorded. “We can wipe out entire landscapes.”

Safer shores: The global #tsunami early warning project led by Joern Behrens has been recognized as a #UNESCO #OceanDecade Project. The Goal is to ensure broad access to reliable tsunami risk assessments, ultimately improving disaster preparedness and response.

Every child can be a gardener in the Seychelles! 🌿
Students engage in gardening and take responsibility for giant tortoises and chickens 🐢, as all schools are now eco-schools. It´s all about #sustainability and cultural practices, climate adaptation expert Beate Ratter reports.

🪨 More than 750 million years ago, these granite blocks were part of a felsic microcontinent. 145 million years ago, they broke away from Gondwana and isolated themselves in the Indian Ocean. Climate expert Beate Ratter reports: “The impressive rocks and beaches of La Digue attract nearly 300,000 tourists each year, requiring water and food while producing wastewater and waste – almost everyone arrives by plane." #climatechange #ocean @hereon @Allianz_Meer

🐠 Corals are crucial as wave breakers and habitats for marine life. However, climate change threatens them. Our climate expert Beate Ratter reports from Seychelles: “Corals break off during storms, also human activities damage them.” In the “Unlock the Sea” program, individuals collect broken coral fragments, grow them in ocean nurseries, and reintroduce them to their habitat. #climatechange #ocean @hereon @Allianz_Meer

🌍 CLICCS in a nutshell – which climate futures are not just possible, but plausible?
#CLICCS #science #climate #climatechange

💰 Weaker ocean circulation may cost trillions

A new study by @felixschaumann and @Edu_Alastrue in @PNASNews reveals that a weakening Atlantic Meridional Overturning Circulation (AMOC) could lead to social costs of several trillion euros by 2100. Less CO2 absorption means more climate change impacts. 🧪 Link to study: https://www.pnas.org/doi/10.1073/pnas.2419543122 #CLICCS @MPI_Meteo

How does #deforestation impact #Amazon rainfall?🌧️
Surprisingly, the total amount of precipitation could remain the same, a new study by Arim Yoon and Cathy Hohenegger, both #CLICCS researchers at the MPI-M, suggests.
However, rainfall patterns will change. Deforestation may lead to fewer but more intense rain events, which could have significant impacts on the regional climate.
