Seminar on Global Paleoglaciers and Alpine Biome Reconstructions
We would like to invite you to an interdisciplinary seminar where we will present work towards global accessibility of paleoglacier reconstructions across disciplines and beyond academia. Within our newly started project (https://mountainsinmotion.w.uib.no/) we invited international colleagues specialised in reconstructing past glacier dynamics from field evidence. Our project goal for the coming years is to integrate glacier reconstructions in mountains worldwide with past distributions of alpine ecosystems to study the legacy of past dynamics on biodiversity hotspots. We hope that today will be the first of a series of seminar talks that will promote interdisciplinary research across the fields of glaciology, geography, and biology. Talks are meant to be accessible to researchers from any background!
09:30 - Seminar Intro - A new interdisciplinary project on the past, present, and future of alpine systems worldwide - PPF-Alpine. Suzette Flantua - University of Bergen and Bjerknes Centre.
09:55 - Reconstructing mountain glaciers in western North America during the Younger Dryas stadial. Helen Dulfer - Charles University, Prague, Czech Republic.
10:10 - Re-visiting the chronology and time-slice reconstruction of the last Eurasian ice sheets. Anna Hughes - University of Manchester, UK.
10:25 - Coffee break.
10:40 - Reconstructing Northern Hemisphere ice-sheet extents for the last 2.6 Ma. Martin Margold - Charles University, Prague, Czech Republic.
10:55 - Towards global mountain paleoglacier modelling for academia and society. Julien Seguinot - University of Bergen and Bjerknes Centre.
11:10 - Questions to all presenters
Please sign up by Thursday 1st of Sept to have enough coffee for everyone: https://forms.gle/xdQcPdprHuC9xf2c7.

“Atlantic Meridional Overturning Circulation instabilities during the last glacial cycle”.
The International Quaternary Webinars are a series of weekly research talks on Wednesdays at 15:00–16:00 CET with topics about Quaternary palaeoclimate in the North Atlantic region. The seminars are hosted by UiB with the University of Massachusetts and open to Quaternary researchers worldwide. The next seminar is this week, Wednesday 21st September and will be given by Yuxin Zhou, University of California, Santa Barbara, USA, who will talk about “Atlantic Meridional Overturning Circulation instabilities during the last glacial cycle”.
Some of the speakers will give their seminars from GEO, and some will be webcast from other locations. Either way, we will meet each week in Realfagbygget Pal.strat.kurssal (Room 2D12C) to watch the seminar and discuss the work presented with the speaker. It is also possible to join the seminars on Zoom if you are not able to attend in person.
Before each seminar on Mondays 15:00–16:00 CET, there is a Journal Club meeting on Zoom to discuss a paper suggested by the speaker that is also open to everyone.
The details for both the Journal Club discussions and seminar schedule and suggested papers are on the Quaternary Webinar webpage.
Workshop on constraining large spread in climate projections
Dear Bjerknes colleagues,
We will hold a workshop on constraining the large spread in climate model projections on 22-23rd September 2022.
The idea was motivated by ongoing activities in RCN funded Columbia and KeyCLIM projects. The goal is to share different methodologies in assessing multi-model ensemble performance and constrain projection uncertainties.
The workshop, which will be held both physically and online (see agenda below for the room and zoom links), is open to project members and to others. But due to the limited space, we ask that those who would like to join physically to fill up the sign-up sheet to secure space and for ordering lunches.
Sign-up sheet, in particular for physical presence:
Please let us know if you have any questions.

Dear BCCR PhD students old and new,
You may have heard of the SciSnack (formerly ClimateSnack) writing group at GFI/BCCR, but for those of you who haven’t, I'd like to tell you a little bit about it now.
The main goal of SciSnack is to provide a friendly and relaxed environment for us to practice and improve our writing, be it scientific publications or outreach in general. We are mostly early career scientists, but the group is open to all who are enthusiastic about honing this valuable skill. We meet as a group once every three weeks, where we discuss writing topics, and give feedback to the short articles (or ‘snacks’) that people write. Once our snacks have been polished, we publish them on the scisnack.com website. You can read more about our aims at https://www.scisnack.com/about/objectives/, and the meeting dates for this semester at https://www.scisnack.com/groups/climatesnack/.
So please feel free to join us at our next meeting, tomorrow 27 Sept from 14:30-16:00 in Room 212 of Jahnebakken 3 (GFI East Wing). You can also join via Zoom.
Contact Andrew Seidl for more information.
Talk: Paleoclimate during the earliest human migration to the High Arctic
Distinguished Professor Raymond Bradley are visiting Bergen and we take the opportunity to arrange a social gathering accompanying his talk (sponsored by UiB polar network). You are invited to pizza and drinks in the new cantina at the Geophysical building (Allègaten 70) at 16:00, Tuesday the 27 of September. Talk starts around 16:15 and please sign up here if you will have pizza:
Title: Paleoclimate during the earliest human migration to the High Arctic
Who: Raymond Bradley, Distinguished Professor, School of Earth and Sustainability, UMASS, US
Bradley is a University Distinguished Professor at School of Earth and Sustainability at the University of Massachusetts Amherst and a leading thinker in the field of paleoclimatology. He’s the author of many books and has been working in and around the Arctic for the last 45 years. In his spare time, he’s an Arctic history enthusiast. In this talk he will present his latest NSF funded project that successfully had its first field season in Wandel Dal, Northernmost Greenland, this summer. From dated artefacts, we know that people first lived in Wandel Dal between 4500-3850 years before present (BP) and again between 2900-2250 years BP. After 2250 years BP, the region was completely abandoned, except for intermittent, short-term use by Thule people, the ancestors of modern Inuit, in the last ~600 years. We also know from archaeological remains that there would have been abundant muskoxen, hares, foxes, birds and char in this “high arctic oasis” during the time they were there. However, much of the history of these northernmost people on the planet, including their settlement, use, and the reasons for their abandonment of the region, remains a mystery. We hypothesize that past favourable climates (warm, stable) and abundant hunting resources would have been critical to sustain life at these latitudes and that climate and environmental changes in the last ~5000 years would have been a critical component in the migration of people in and out of this region. With this project, our interdisciplinary team seeks to understand the climate history of Tunup Avannaarsua and to place the Paleo-Inuit occupation of Wandel Dal into a broader climate perspective. Using the site "Pearylandville" on the shores of Nedre Midsommersø (Lower Midsummer Lake) as our base, we will retrieve and analyze lake sediment cores from the lake (and nearby lakes) to understand the ~5000-year climate history of this region including temperature, rainfall, lake ice cover, as well as the presence of terrestrial plants and animals. We will also map the key archaeological features of the lake and adjacent fjord, and better constrain the timing of these sites and their occupation. Together with modelling, we will develop a comprehensive understanding of the human-climate interactions in Wandel Dal and how they relate to broader shifts in glacier fluctuations, ocean circulation, and polynya dynamics, and the Holocene climate history of the Arctic.
See you soon,
Lars Henrik and Jostein (for the polar network)
“How can I move towards a more sustainable diet, and why does it matter?”
On Wednesday the 28th, at 16:15, there will be a talk and Q&A session titled “How can I move towards a more sustainable diet, and why does it matter?”, by Karl Purcell, PhD candidate at UiB and the Bjerknes Centre for Climate Research.
The talk will take place in the Realfagbygget building, Auditorium 1: https://link.mazemap.com/38vuChwg
àFree food provided (plant-based snacks and coffee)
As we move towards an increasingly warmer world, and see news about unprecedented environmental degradation, one can wonder if she/he can do something about this. Solutions are known, such as green energies. However, one option often left off the table is what foods to bring to one’s table.
In this talk I will discuss how we can personally move towards a diet that drastically reduces GHG emissions, allows natural carbon sequestration, while also reducing negative impacts such as land use, freshwater use, eutrophication, biodiversity collapse, and the unnecessary killing of trillions of sentient beings. Practical aspects and implementable actions will be presented, and there will be a Q&A session.
If you plan to join, please sign up using this form by Friday 23rd, to order enough snacks J: https://skjemaker.app.uib.no/view.php?id=13374827
Looking forward to seeing many of you!
All the best,
PS: the talk might be available by zoom, and will be recorded.
