Vi skal granske FN tala om hav og is

Onsdag sist veke la FNs klimapanel fram sin siste rapport om hav og is. Panelet varslar der om stor havnivåauking blant anna på grunn av meir issmelting på Sørpolkontinentet (Antarktis), men kunnskapen om kva som vil skje med isen på Sørpolen er mangelfull. Tala i rapporten er usikre og meir forsking må til.

Denne forskinga startar vi no opp gjennom eit nytt stort EU (Horisont 2020) prosjekt med namnet Tipping Points in Antarctic Climate Components (TiPACCs). I prosjektet skal det sjekkast ut om det er vippepunkt («Tipping Point») i det Antarktiske klimasystemet. Det betyr punkt der akselerasjonen på temperaturen i havet aukar. Slike vippepunkt kan føre til hurtig og uventa auka smelting av isen.

NORCE leier arbeidet i TiPACCs prosjektet i tett samarbeid med nokre av Europas største forskingsinstitutt og deira fremste ekspertar på hav og is i Antarktis. Store og avanserte datamaskinmodellar skal brukast til å studere kva som skjer med isen på sørpolen og i havet utanfor slik at FNs klimapanel neste gong kan gi eit meir sikkert varsel om kor mykje havnivået vil stige.

Førstkommande onsdag er det Kick-off her i Bergen og i forkant av vårt forskarmøte inviterer vi til informasjonsmøte for pressa. Hit kjem nokre av nøkkelforskarane frå prosjektet. Det vert korte innleiingar og tid er sett av til intervju og spørsmål til forskarane.

Jørgen Randers from BI visiting UiB and the Bjerknes Centre

On Tuesday Oct 8 Jørgen Randers from BI will visit UiB and the Bjerknes Centre. From 8:30 to 10:00 Jørgen Randers will give a talk based on the «transformation» report at the «Forum for science and democracy» (breakfast from 0800) at Christie Café. The talk is open to all (in Norwegian).

At 11:00 - 13:00 he will visit the Bjerknes Centre and present the low-complexity ESCIMO model (http://www.2052.info/escimo/). He will discuss the model and its results, and would like to have feedback on both. If you want to attend the meeting with Jørgen Randers here at Bjerknes, please give me a word so lunch can be ordered (I know it is not the best day due to autumn vacations and also the COMPACT pre-workshop). It will be in the large meeting room in the Vest Ving (Bjerknes).

Jørgen Randers is one of the pioneers within sustainability and planetary boundaries research (e.g. co-authored the famous «Limits to growth» book in 1972) and is still active (e.g. lead author of the «Transfomation is feasible» report with Stockholm Resilience Centre, 2018). See his bio here https://en.wikipedia.org/wiki/J%C3%B8rgen_Randers.

NERSC seminar: Chasing Water: How ocean currents transport plastic and plankton around the globe

Dear All,

Welcome to seminar by Dr. Erik van Sebille in the Lecture room at the Nansen Center, Monday October 21 at 11:15:

Title:

Chasing Water: How ocean currents transport plastic and plankton around the globe
Dr. Erik van Sebille - Institute for Marine and Atmospheric Research, Utrecht University, Netherlands

The ocean is in constant motion, with water circulating within and flowing between basins. As the water moves around, it carries heat and nutrients, as well as planktonic organisms and plastic litter around the globe.
The most natural way to study the pathways of water and the connections between ocean basins is using particle trajectories. The trajectories can come from computing of virtual floats in high-resolution ocean models.
In this seminar, Erik will give an overview of some recent work with Lagrangian particles. He will introduce the new open-source oceanparcels.org framework and show applications to marine microbiology and ecology, palaeoclimatology and plastic pollution. Central to each of these studies is the question on how connected the different ocean basins are, and on what time scales water flows between the different regions of the ocean.

Disputas: Francesca Jaroszynska

Title of thesis: "Climate and biotic interactions – Drivers of plant community structure and ecosystem functioning in alpine grasslands" Please follow link for more information.

Seminar talk: Seasonal and interannual climate reconstructions derived from fossil giant clam shells (Tridacna) from the Western Pacific Warm Pool : implications for paleoENSO studies.
