We are expanding quite rapidly at DMI currently – part of a strategic plan to ensure that we are primed for a generational shift at DMI, but also reflecting some of the themes I touched on yesterday – an expansion into climate services and the development of new machine learning based models and advanced statistical techniques for weather and climaet applications. Note also that the remote sensing part of NCKF
UPDATE: A new position advert has been added:
0) Climate Scientist with Focus on Decadal Climate Prediction
Our sister units also have some interesting postings out that would also crossover with the work we do in our section on the climate of Denmark and Greenland.
4) Remote sensing and/or machine learning specialist for automated sea ice classification from satellite data – building on the very successful project ASIP
Today the European Council is debating (behind closed doors), the proposed Nature Restoration Law – there has been heavy lobbying by several EU countries to water down the provisions. I believe this is a mistake and last week I and almost three and a half thousand other scientists signed a petition saying so.
It has now been reopened for signatures. Please do sign if you feel strongly about it. It’s worth a read anyway as the organisers (probably being scientists!) have written out what the agreement means in admirable clarity:
Rough land which has been allowed to turn into a wildflower haven in Copenhagen
I am a climate scientist who has become increasingly interested in and concerned about biodiversity. I have had a deep love and sense of wonder about nature since I was a kid – and probably my interest in glaciers and weather and climate have in in part grown out of that. I’m not a biodiversity expert, but I am acutely aware of the impact climate change is already having on the biosphere. It is at a fundamental level very hard to separate climate from biodiversity and probably unwise to try.
In the past I’ve considered it was a scientist’s duty to advise impartially and therefore to be politically completely inactive, I have regretfully come to the conclusion that actually, maybe we as a community do need to push a little more firmly in the direction our science is actually pointing us. Perhaps it is in fact irresponsible not to be involved?
As the great atmospheric chemist and Nobel Laureate Sherwood Rowland once said (in 1986!):
“After all, what’s the use of having developed a science well enough to make predictions, if in the end all we’re willing to do is stand around and wait for them to come true?”
The petition I linked to above has been organised by german scientists, experts in ecology and biodiversity. They emphasise:
“Being proactive is thus important. We would therefore appreciate if you found your way of communicating this letter in your surroundings, and help delivering the science to whoever may be interested in it. The purpose is not to lobby but rather to support, to offer help, maybe even mediate where possible.”
We’re scientists and we’re also public servants.
Use us to help guide policy. If scientists are ringing alarm bells, then somewhere there is a fire…

The project is led by Professor Christine Hvidberg at the Niels Bohr Institute and there is a really nice interview with her on their website about our plans that’s worth a read. I’m co-PI and lead on surface mass balance processes and coupled climate models within the project so I thought it might be worth giving a quick overview of what we hope to achieve.
TL;DR? We will be improving estimates of and assessing the uncertainties in sea level rise projections from the two big ice sheets in Greenland and Antarctica.
Every science proposal has a graphic like this somewhere showing how the whole project hangs together. This is ours…
Slightly longer version: we’re using new approaches from materials science to incorporate “new” physics in ice sheet models. We’re also integrating in-situ observations and satellite data into our model frameworks and using these to train machine-learning tools. My work package will emulate our physics based numerical climate models to expand the ensemble and generate a statistical approach for assessing ice sheet stability as well as investigating important feedbacks between different elements of the earth system. Finally, we (or rather my colleague Christian Rodehacke and his postdoc) will run our coupled climate – ice sheet model (EC-EARTH-PISM), including these advances, to generate new sea level rise projections.
The outputs from all these experiments will be communicated and developed in collaboration with the Danish Klima Atlas (Climate Atlas) to ensure we are focused on the right kind of data and time periods for use by stakeholders and local populations when it comes to adaptation planning.
Current projections of change in average sea level around Denmark from the klima atlas
So why this project?
One of the most iconic images to come out of the last IPCC 6th asessment report (at least in my little corner of the climate science universe) is this one on sea level rise projections out to 2100.
Much of climate science has, at least to some extent been “solved”. At least in the sense that we understand the mechanisms and processes quite well and the remaining uncertainty is to some extent tinkering around the edges, often bound up with uncertainty on scenario, or related to impacts – there’s still quite large uncertainty on what will happen to the Amazon rainforest at different levels of emissions for example. However, sea level rise is really an exception to this. It’s very difficult to be sure that some very unpleasant surprises are really implausible.
The IPCC for example, concluded that sea level rise of 15 metres or more by 2300 can’t be ruled out, even if it seems rather unlikely. And this poses a pretty large problem to planners, politicians, stakeholders and providers of coastal services. Working out how far and how fast we expect the sea to rise is really our challenge.
But there is also a risk of abrupt and extreme sea level rise that could come round the corner to surprise us. However, it’s hard to know how likely this is or even how to evaluate that risk.
Where PRECISE differs is that we have the flexibility within this project to develop new and innovative techniques that we’re not quite sure will work: especially the development of machine learning tools.
The EU science budget is a brilliant thing, but risky research is difficult to get through, the Move Nordisk challenge centres allow us to try really new and, yes, risky techniques. Though climate is a new topic for them, so we’re very much test bunnies in this new phase of funding science for them.
So what are we going to be doing practically?
Measuring snow pack properties in Greenland, with the help of the Lego scientists..
Our partners at NBI include Joachim Mathiesen, Helle Astrid Kjær, Aslak Grinsted and Nicholas Rathmann. They will be focusing on assembling field data from both ice sheets, and developing new physical solutions for ice sheet models based on solutions from materials science. They will be looking at phase field approaches for ice flow, at new solutions for calving and ice fracture and integrating these into ice dynamical models. NBI will also be doing fieldwork to collect new surface mass budget (SMB) data from the ice sheets.
A new ice fracture appears, how to understand and model these is a key part of the NBI contribution in PRECISE project.
The SMB part of the work is part that I’m especially involved in. Not just in modelling SMB with our climate and weather models as we do on the polar portal but also in getting a much better understanding on the uncertainty in these models associated with precipitation (which is much higher than that associated with e.g. temperature, especially when it is snowfall). So new observations with a high time resolution will be key for improving our current snowpack models.
A shallow ice core, in this case sea ice, but part of the fieldwork will focus on taking more of these samples and doing isotope analysis on situ to get high quality data on snowfall accumulation
We will also be working on bringing regional climate emulators into use over both ice sheets to see how varying starting conditions will vary the outcomes. We know that on a chaotic system like weather starting conditions are key and emulators allow us to do many many more experiments than with our physics based numerical codes alone. It’s pretty cutting edge stuff right now but I know several groups are working on this – including this fantastic paper that recently came out of the Delft/Leuven group, which really shows what is possible
Our other collaborator, Hilmar Gudmundsson at University Northumbria Newcastle will be working on implementing these processes in ice sheet models and examining how plausible instability in ice sheet simulations is using ensembles of multiple model simulations. They will also be using and developing their ice shelf emulator to look at basal melting and investigating the potential instabilities in Antarctic ice shelves that could lead to abrupt sea level rise.
The project will receive 42 million Danish kroner in total (about 5 million euros) of which 8 million dkk will fund work at DMI, work to be carried out by 2 postdocs and a PhD student (so if this sounds like something you’d be interested in working on do get in touch) over the next 6 years from September. In fact most of the funding we have received will go directly to early career scientists, there is nothing in the budget for us seniors! Naturally this has some disadvantages, but given the rapidly aging population within Europe and European science, I see it as a positive and we have lots of cool summer schools, bootcamps and other networking activities planned that will hopefully reach out beyond PRECISE to the rest of the ice sheet – climate community.
Yesterday, I attended a mini conference on power to X and the potential to generate green synthetic fuels in Greenland.
Power to X became a big thing in Denmark a few years ago and the government is keen to promote it. Danish company Topsoe are currently building a green fuel facility in Herning and they have a nice explainer on their website of the concept.
In Greenland the fuels could be anything from hydrogen to methanol (though I learnt methanol is least likely as it requires a CO2 source that Greenland doesn’t have, ammonia seems the most plausible initially).
It was an interesting meeting, lots of different companies, institutions and the Greenlandic MP Aaja Chemnitz as well as academics were in the room. The emphasis was very much on the social and economic aspects of power to X, but as the title implied: Greenland has the potential to be the “world’s largest energy island.” From a local point of view, Greenland has very high per capita emissions and is heavily dependent on energy imports for transport, though a majority of electricity, at least in the south west, is already hydropower.
Many other smaller and more remote communities however are dependent on diesel generators for heating and power as well as for shipping, fishing and flying between communities.* Transitioning away from these fuels will be challenging but the potential for much larger developments is clear.
Head of development at NunaGreen (the recently rebranded and reoriented NunaOil), Rasmus Wendt, emphasised just how cheap and in theory at least, abundant, Greenland hydropower is. Probably some of the cheapest electricity in the world is generated by Greenlandic dams already operating or planned. And indeed the potential is massive. As the ice sheet melts, enormous amounts of water are produced more or less endlessly in Greenland. It will take at least a thousand years to melt the whole ice sheet, even under a high emissions scenario. We’re not going to run out of water soon.

Wind energy too is extremely underdeveloped but potentially huge in Greenland. The problem is of course, all that potential energy is a long way from the end users as this screenshot from the global wind atlas, shared by energy scenario planner Brian Vad Mathiessen shows well.

By sheer coincidence, this morning I stumbled over this article in the Dutch newspaper NRC on mastodon about the large green hydrogen facility currently under construction by Shell in Rotterdam.
It’s a really interesting read – (if you don’t speak Dutch try DeepL translation) and I was struck by many of the same issues being raised there as in the Greenland meeting: lack of trained staff, uncertain commercial environment, cost and competitiveness with other energy sources. Unlike in Greenland, energy in the Netherlands for producing synthetic fuels is scarce, but the market for using the energy is huge and nearby, and given the EU’s ambitions to produce and, crucially, import large amounts of hydrogen fuel by 2030, it seems like many of the important stars are aligning. Importing ammonia to Rotterdam for cracking back into hydrogen seems like it could actually be a viable future for Greenlandic generated fuels in Greenland he medium to long term.
We at DMI are shortly starting a project within the National Centre for Climate Research framework looking at exactly the potential to generate renewable energy from a climate and weather angle. But what I took away from yesterday’s meeting is that while the physical potential in Greenland really is HUGE, the regulatory environment – and probably the local population – is supportive, the economic certainty is not quite there yet.
It felt a bit like being in a bunch of young seabirds clustered on the edge of the cliff, none quite daring to take the flight, in spite of the undoubted rewards. And indeed, this seems the situation in the Netherlands too. I was especially struck by this quote in the NRC piece:
“Another problem is that many parties are just waiting for each other to take the first step so that they themselves dare to go. Producers, for instance, invest only sparingly because they are not sure whether there will soon be customers, and customers in turn hesitate because they are not sure whether the producers will deliver. The classic chicken-and-egg story.” (Translated with DeepL)
Chris Hensen, NRC, 17thnMay 2023 “De Europese waterstofambities zijn groot, maar bedrijven zijn nog altijd afwachtend”
Perhaps the diving in of Shell, a company that can afford to risk investing a billion Euros in a new facility in Rotterdam, is what the development of Power to X needs?
BP, Air liquide and Uniper already have plans to build follow on plants in Rotterdam. Once one of the birds have taken flight, others will surely follow.
Thanks to Aalborg University,and especially my Danish Arctic Research Forum colleague Carina Ren for an interesting and inspiring meeting.
*(As an aside, I was reflecting while on fieldwork just how difficult removing fossil fuels from scientific work in Greenland will be. We rely on petrol generators to power equipment and oil stoves to warm tents. What if we could develop an easy to operate “tabletop” (or even just room sized) electrolysis system to generate clean fuels from e.g. wind energy, that we could burn instead of paraffin and/petrol? I’d invest in that and it would be a quick win for Greenland science.)
Inside of the tent during fieldwork, note the primus stove, running on petrol, for melting ice for water and food and the paraffin powered oven to keep the inside warm and dry while camping.
My employer DMI, and specifically my team at the National Centre for Climate Research are recruiting.
Not an earth-shattering revelation perhaps but these are premium research jobs, and this is probably a once in a generation opportunity in Denmark.
Let me explain. They are full time and permanent positions, working right at the cutting edge of both basic climate research, and importantly, climate services. You can see the full adverts at the links below:
DMI scientists collaborating with local hunters in the field in Greenland
I call these positions once in a generation positions because these kind of positions just don’t come up very often. Part of the reason these are now available is related to the generation change* that is coming to DMI. Right now we are fortunate also to have a number of large EU funded projects as well as danish funding for our Climate Atlas and new hydrology department which is giving us the opportunity to plan for the long term.
Sea level rise is an existential threat for Denmark, at least in the long term and we are putting a great deal of effort not just into the science of melting ice, tipping points and so forth to try and assess the potential risks, but also into planning climate adaptation and mitigation in the short and medium term.
The new positions related to climate and ice sheets and sea level rise will have some flexibility with them in terms of how the jobs evolve and research directions. There will certainly be opportunities for whoever is hired to steer in their own direction and initiate their own research programmes within the broad frame of the topics. I can certainly also only praise the management for the generally supportive and research positive encouragement.
I’d like to help cast the net wide and deep to get as strong a pool of candidates as possible, so please do feel free to get in touch with me either here or via the usual email, and other social media feeds if I can help at all. And if you have good students, postdocs or others, please do share.
We will be holding some “open house” events where you can come in person to visit DMI or sign on in a virtual event to hear more about the positions, about DMI and what it’s like to work in Denmark. Again get in touch to hear more about those.
*”Generations skift” in Danish – I have not looked at the statistics but I suspect many public institutes, including weather and climate services are greying. There was an expansion during the 80s and 90s as numerical techniques became more widespread and integrated into weather prediction and by extension climate – many of the staff employed then are getting close to retirement. In my view DMI is wise to start trying to replace these staff now so there will be continuity and knowledge exchange before it becomes a problem.
In the before times I would usually spend this week walking around a world class city humming an old 80’s hit (- don’t ask me why it was so durable in my head, probably something to do with being an impressionable age at a time when access to pop music meant half an hour on a Thursday evening).
Anyway, it is the time for EGU… Sadly I will not be wandering the streets of the ever beautiful (and most livable) capital of Austria this year. I have to get some actual work done, but I’m following the #EGU23 on mastodon and hoping to catch a few highlights on the sides. I do have a poster, which will be capably presented by PolarRES PI Priscilla Mooney and my DMI Colleague Abraham Torres on Thursday.
The topic is our PolarRES project – an ambitious Horizon 2020 effort to produce a large ensemble of regional climate simulations over both poles. These are state-of-the-art regional climate models run at unprecedented high spatial resolution and all data will be made open access and free via the CORDEX project.
I will also put it here later – feel free to comment here or ask questions on mastodon or get in touch by email if it sounds exciting.

Last year I co-organised a bootcamp for early career researchers on Arctic processes in the CMIP6 models. It was super fun and would not have been possible without the support offered by Anne Fouilloux, Tina Odaka and colleagues from the Pangeo project. Their poster is super interesting and if you’re interested in optimising the use of big climate data, go and check it out!

Excitingly, at least 3 of the projects at the bootcamp will also be presented at EGU this year. So, lots to be getting on with, for now, here’s a link to Ultravox’s finest…
Back in Denmark after 2 weeks in Greenland. Always a bit strange to come back, not just that transition from Arctic cold to European Spring but the sheer abundance of the fertile mid-latitudes, colours, plants, trees, the sheer number of people.
Not to mention that expedition frame of mind, where you are really focused on accomplishing a given set of often quite complex tasks (almost) without distraction. It is the ultimate deep work task, and naturally readjusting to family life, not to mention the tsunami of work tasks left on hold is… difficult.
The town was formerly a summer hunting spot, but after Thule was decided on, the community was moved to Qaanaaq year round. It has an association with the famous Danish explorer Knud Rasmussen, whose old house is a museum (allegedly. I’ve never actually had time to visit it..)
This year we again visited the glaciers at the head of the Inglefield Fjord – expanding a new research programme we piloted last year. We also did a lot of work on the sea ice – not just Steffen Olsen‘s ocean programme, but a new NCKF research programme looking at biological productivity and carbon cycling in the fjord, led by Anna Pedersen, a DMI PhD student also at the University of Southern Denmark. I and another colleagues also did a lot of work on snow processes that is something of a pilot programme for a processes project we’d like to establish next year that will also involve (hopefully) our weather forecasting colleagues and perhaps also the GEUS PROMICE programme.
All of this work involved 6 days of travelling over and camping on the sea ice, plus an additional day trip. We were lucky with the weather, although it was *extremely* cold, around -25 to -28C most days, and dipping well below -30C at night (though being after the equinox it was never truly pitch dark). However, in general there was little wind, no fresh snow (which can really slow the dogs down as they struggle to pull through deep soft snow) and the sun shone every day. This meant we basically managed to achieve the full planned programme – including our extra-optimistic goals – which almost never happens in fieldwork.
I intend to write a whole series of posts based on what we have been doing scientifically and technically as well as some general observations. There have been various hints already in my preferred social network. The whole trip was super inspiring, it’s always valuable to get out and observe the real world when you’re trying to model it, understand it and make projections of sea level rise.
I also promised to make another Lego scientists series and took quite a few photos in between times to do so. However, the research programme was packed, so I had no time at all to make the comic during fieldwork, that will have to wait a few weeks.
Expect my pixelfed account to host gratuitous numbers of dog pictures. And ice pictures. And unexpectedly clear blue skies. For now it’s time to unpack, get the washing machine going and spend some time with my family.
As ever, thanks to my amazing colleagues Steffen Malskær Olsen, Andrea Gierisch and Anna Pedersen for an incredible trip and to DMI station manager in Qaanaaq Aksel Ascanius without whom most of this work would be impossible.
Special thanks to our friends in Qaanaaq, the local hunters, whose unfailing energies and knowledge are absolutely essential to these scientific projects. We literally could not do this without them and of course their dogs.
I must also credit DMI and the Danish Government for funding via the National Center for Klima Forskning and thanks also to Horizon Europe projects PROTECT on sea level rise and PolarRES for additional inspiration and funding and to my colleagues at the Horizon Europe/NERC project OCEAN:ICE for indulging my two weeks away. All three projects will benefit from the insights gained in this fieldwork.
I wrote this series of comics to amuse and inform my kids while I was on fieldwork a few years ago. It turned out to be quite a success and my kids classes both read the Danish versions at their school.
Last year I started https://icemangoeshome.wordpress.com/more-arctic-adventures/ the further adventures of batgirl on the ice with her new friends the Lego scientists and a couple of stowaways.. but last year’s season was extremely busy and I never managed to finish it.
I asked yesterday on mastodon if I should do another this year, and the only feedback I got was I should try to finish the one I started last year. So maybe that’s what I’ll try to do. It’s always challenging fitting around field tasks though so no promises.
This is just a quick post from the airport: you’ve been warned, bat girls and her friends are on their way back with a new season!
It’s a really thorough introduction to the climate system and all the natural sources of climate variability and cycles of change, including links to sources. Well worth taking your time over with a morning cup of tea and probably I’ll assign it as an introduction text for BSc students (and management) on the big picture of climate change.
I also love it for the introduction where multiple eminent and respected scientists are asked what they’d buy with all the dollars they’d have if they were given one dollar every time someone asked them about “natural climate cycles”. As you might expect, the answers range from heat pumps and solar panels to new bicycles and a time machine.
Not sure what I’d use it to pay for, possibly a new postdoc position to work on snow and ice processes?
*as an aside: I haven’t read Ars Technica in ages. And it’s funny because I remember that when I first started on twitter way back in 2010 there were *a lot* of good articles shared from there on the bird site. Somehow they either were not shared or got suppressed and I stopped seeing them. I’m not sure if that was due to the algorithm or different people I was following. One of the nice things about mastodon is that without an algorithm (and crucially, by following *a lot* of people!) there is a chance to see a much greater diversity of different media. It feels a bit like seeing a different internet, outside the standard walled garden.
I’ve been on holiday this last week and I’m combining the trip to the UK with a visit to colleagues and collaborators at the University of Leeds. I’ve also been nabbed while I’m in Leeds to give a wider interest talk at the Royal Meteorological Society Yorkshire branch in Leeds.
I’ll be discussing ice sheets, their contribution to sea level rise and how the future is looking. There may also be some nice photos from our fieldwork in Northern Greenland for those who like dogs, icebergs and snow…
If you’re in Leeds and fancy joining you’re most welcome to register and attend at this link.
In general, I’m trying to reduce my travel this year, last year, with all the rolled over meetings from the COVID times was disruptively busy with work travel, it makes it challenging to actually get the work done. So I think combining work and holidays and rolling up meetings into a block is the way forward.
Although I very much appreciate the opportunity to present online at various meetings, I’m less convinced about hybrid meetings where the purpose is mostly scientific discussions, that is something that works much better either all online or all in person in my opinion, but I think they work well when the aim is to present new and ongoing work (like EGU).
For those who are interested but can’t attend I will see if the talk tomorrow will be recorded and can be uploaded somewhere. Here’s the abstract:
Frozen Threats: Understanding the Role of Ice Sheets in Sea Level Rise
In this talk, we will delve into the world’s ice sheets and explore their importance in the climate system. Ice sheets are the largest stores of freshwater on the planet, their size and location means they influence our climate but their interactions with the atmosphere and ocean are complex. As the world warms, they will inevitable have an impact on sea level. Adapting to sea level rise will be one of our civilisations biggest and longest challenges, so understanding ice sheets is now of critical importance. They are also beautiful and fascinating environments in their own right. In this talk I will discuss some of the scientific challenges, but also show how far we have come in understanding ice sheets and glaciers.
