What can Greenland ice cores tell us about winter extreme events over Europe?

Introduction Human-caused climate change is increasing the frequency of extreme weather events around the world, and Europe is no exception. These events typically last from a few days to several week...

🔬In our new study, my first-author paper, we investigated whether Greenland ice cores could provide information about the occurrence of extreme winter events in Europe. ✅ Short answer: Yes, they do. 📄Read the study (open access, no paywall) cp.copernicus.org/articles/22/... 🧵Long answer ⬇️

Northern Greenland transect stacked ice cores as a proxy for winter extreme events in Europe

Abstract. High-resolution ice core records from the Greenland ice sheet provide critical insights into past climate variability across seasonal to multidecadal timescales. A key proxy in these reconst...

After 35 unforgettable days at sea, the i2B expedition has come to an end. The team retrieved nearly 250 meters of sediment cores from key sites across the #Arctic Ocean — records that will help unravel the story of past warm climates. 🔗 Read chief scientist Jochen Knies’ reflection: arcg.is/0favaf0

✨ The power of teamwork in the Arctic ❄️🚢 From hauling heavy cores to processing samples, every task on R/V Kronprins Haakon depends on collaboration. Read @alexgag11.bsky.social reflections on how teamwork makes science possible: 🔗 arcg.is/0favaf0 📸 Norbert Nowaczyk @paleodyn.bsky.social

🚢 4 weeks at sea, 6,400 samples, and a record-breaking 22 m core ❄️🌊 The i2B team is piecing together the Arctic’s climate history, sample by sample — day and night. 🔗 Read co-chief scientist Stijn De Schepper’s update: arcg.is/0favaf0 📸 Tim Kalvelage @bjerknes.uib.no

🚨 A small break from cruise updates to say that: We’re hiring! i2B is looking for a Postdoc in Arctic Marine Geology and Marine Geophysics. Find out more about the position here: www.jobbnorge.no/en/available... Please share with your networks 😊

🎉❄️The i2B Expedition Team has reached the North Pole 🚢🌍 Today, the i2B expedition celebrated its halfway point at the most symbolic place imaginable: the North Pole. Read more about our stop: 🔗 arcg.is/0favaf0 @paleodyn.bsky.social @bjerknes.uib.no 📸 @rhewlif.xyz

💭 Read the reflections of @paleodyn.bsky.social PhD student @alexgag11.bsky.social, who traded screens for the Arctic Ocean. Aboard R/V Kronprins Haakon, he cut open sediment cores holding thousands of years of history and sampled water from 4000m below. 🚢❄️ 🔗 arcg.is/0favaf0

First week update: We have been sailing day and night, moving east to west not far from the northern part of Svalbard. A few days ago, we reached the Yermak Plateau, where we carried out several measurements and collected sediment cores. @i2b-erc.bsky.social @paleodyn.bsky.social

Paper alert! 🚨 Ever wondered how ENSO contributes to Marine Heat Waves #MHVs? In the study conducted in collaboration with PhD candidate Alessandro Gagliardi (@alexgag11.bsky.social), the authors isolated the effect of ENSO in driving SST variability, including MHV extremes! doi.org/10.1175/BAMS...

I attended #EGU25 for the first time. It was an amazing opportunity to meet researchers from all over the world and to connect with many different research communities. I presented a poster and received a lot of constructive feedback and ideas for future work.

Thanks to all attendees & everyone presenting exciting research in last Friday‘s first-ever #EGU25 session on Atmospheric Rivers! See you next year! #atmosphericrivers

Climate extremes are a rising concern to Europe as they are projected to increase in frequency and magnitude in the future. But what about the past? Alessandro Gagliardi (@alexgag11.bsky.social) will present a poster at #EGU25 showing how ice cores are used to unveil past climate extremes!

Our Paleoclimate Dynamics group is now on Bluesky! Stay tuned for more updates on publications, the endeavors of our scientists and news on our events!

I am excited and grateful for the complimentary membership offered by the Royal Meteorological Society for 2025. Here is a picture of my welcome pack! I look forward to engaging with the community and sharing my contributions to the field.

I have just returned from one of my dream experiences: being at sea on a research vessel! I traveled from Bremerhaven to the Canary Islands aboard the icebreaker Polarstern during expedition PS145/1, where I participated in the Echosounding Training Cruise organized by POLMAR.

Any paper that statistically validates the #Bromine enrichment in #Greenland ice cores as a proxy for sea ice? And maybe even that Bromine enrichment captures overall historical of #Arctic #sea #ice variability? Yes! Read our last work by @FedericoScoto www.sciencedirect.com/science/arti...

Yesterday I went to support the Werder Bremen women's football team. It was a good match with a fantastic last-minute goal! Go #Werderfrauen!

The outstanding scientific school on Ice Core Analysis and Techniques (ICAT) at the Niels Bohr Institute’s Physics of Ice, Climate, and Earth (PICE) in beautiful Copenhagen has just ended. I am eager to apply the knowledge I’ve gained to my research.
