When I first went to Alaska in 2008, “Unbaking Alaska“ was the title of the reporting project on how climate change is affecting the region and what the world might be able to do about it. I had to explain the title to my German colleagues, unfamiliar with the “Baked Alaska” dessert, while my North American and British colleagues thought it was a quirky, witty little title.
This week, when I saw an article in the Washington Post entitled “As the Arctic roasts, Alaska bakes in one of its warmest winters ever”, I found the “dessert” had become a little stale .
The thing about “Baked Alaska” is that the ice cream stays cold inside its insulating layer of meringue. Unfortunately, all the information coming out of Alaska and the Arctic in general at the moment, suggest that the ice is definitely not staying frozen.
Too hot for comfort?
In the Washington Post article, Jason Samenow refers to this winter’s “shocking warmth” in the Arctic, some seven degrees above average. Alaska’s temperature, he says, has averaged about 10 degrees above normal, ranking third warmest in records that date back to 1925. Anchorage has found itself with a lack of snow.
“This year’s strong El Nino event, and the associated warmth of the Pacific ocean, is likely partly to blame, along with the cyclical Pacific Decadal Oscillation – which is in its warm phase”, Samenow writes. Lurking in the background is that CO2 we have been pumping out into the atmosphere over the last 100 years or so.
Sea ice on the wane?
Meanwhile, the Arctic sea ice is at a record low. Normally, in the Arctic, the ocean water keeps freezing through the entire winter, creating ice that reaches its maximum extent just before the melt starts in the spring. Not this time.
Yereth Rosen wrote on ADN on Feb. 24th the sea ice had stopped growing for two weeks as of Tuesday. He quotes the NSIDC as saying the ice hit a winter maximum on February 9th and has stalled since.
“If there is no more growth, the Feb. 9 total extent would be a double record that would mean an unprecedented head start on the annual melt season that runs until fall”.
This would be the earliest and the lowest maximum ever. Normally, the ice extent reaches its maximum in early or mid-March.
The most notable lack of winter ice has been near Svalbard, one of my own favourite, icy places.
The experts say it’s too early to say whether this is “it” for this season. There is probably more winter to come. But even if more ice is able to form, it will be very thin.
Toast or sorbet?
Coming back to those culinary clichés: Samenow in the Washington post writes of the second “straight toasty winter” in the “Last Frontier”. The links below his online article are listed under “more baked Alaska”. Amongst them I find the headline: “As Alaska burns, Anchorage sets new records for heat and lack of snow” and “Record heat roasts parts of Alaska”.
The trouble comes when these catchy titles become clichés and somehow stop being quirky.
Don’t we run the risk of not doing justice to the serious threat climate change is posing to the most fragile regions of our planet? Sometimes I worry that the warming of the Arctic is becoming something people take for granted, and, even more dangerous, something we can’t do much about. At times I sense a cynicism creeping in.
I for one will be keeping my oven-baked cake and chilled ice cream separate this weekend.
Is it possible to un-bake Alaska? Food for thought.

Record permafrost erosion in Alaska bodes ill for Arctic infrastructure
Sitting in my office on the banks of the river Rhine, I am trying to imagine what would happen if the fast-flowing river was eating into the river bank at an average rate of 19 metres per year. It would not belong before our broadcasting headquarters, the UN campus tower and the multi-story Posttower building collapsed, with devastating consequences.
Fortunately, Bonn is not built on permafrost, so we don’t have that particular concern.
Record erosion on riverbank
The record erosion German scientists have been measuring in Alaska probably hasn’t been making the headlines because it is happening in a very sparsely populated area, where no homes or important structures are endangered.
Nevertheless, it certainly provides plenty of food for thought, says permafrost scientist Jens Strauss from the Potsdam-based research unit of the Alfred Wegener Institute for Polar and Marine Research (AWI). He and an international team have measured riverbank, erosion rates which exceed all previous records along the Itkillik River in northern Alaska. In a study published in the journal Geomorphology, the researchers report that the river is eating into the bank at 19 metres per year in a stretch of land where the ground contains a particularly large quantity of ice.
“These results demonstrate that permafrost thawing is not exclusively a slow process, but that its consequences can be felt immediately”, says Strauss.
With colleagues from the USA, Canada and Russia, he investigated the river at a point where it cuts through a plateau, where the sub-surface consists to 80 percent of pure ice and to 20 percent of frozen sediment. In the past, the ground ice, which is between 13,000 and 50,000 years old, stabilized the riverbank zone. The scientists, who have been observing the location for several years, demonstrated that the stabilization mechanisms fail if two factors coincide. That happens when the river carries flowing water over an extended period, and where the riverbank consists of steep cliff, which has a front facing south, and is thus exposed to a lot of direct sunlight.
Minus 12C average no safeguard
The warmer water thaws the permafrost and transports the falling material away, and in spite of a mean annual temperature of minus twelve degrees Celsius, summer sunlight makes it warm enough to send lumps of ice and mud flowing down the slope, according to Michail Kanevskixy from the University of Alaska Fairbanks, lead author of the study.
Overall, between 2007 and 2011, the cliff – which is 700 metres long and 35 metres high – retreated up to 100 metres, resulting in the loss of 31,000 square metres of land area. That is a large area, around 4.3 football fields, the scientists calculate.
In August 2007, they also witnessed how fissures formed within a few days, up to 100 metres long and 13 metres deep.
“Such failures follow a defined pattern”, says Jens Strauss. “First, the river begins to thaw the cliff and scours an overhang at the base. From here, fissures form in the soil following the large ice columns. The block then disconnects from the cliff, piece by piece, and collapses”.
Infrastructure under threat
Although these spectacular events happened far from populated areas and infrastructure, the magnitude of the erosion gives cause for much concern, given the rate at which temperatures are increasing in the Arctic. The scientists want their information to be used in the planning of new settlements, power routes and transport links. They also stress that the erosion impairs water quality on the rivers, which are often used for drinking water.
But what about those areas of the High North where there are settlements and key infrastructure? Russia is starting to get very worried about the effects of increasing permafrost erosion.
Last month the country’s Minister of Natural Resources, Sergey Donsjkoy, expressed grave concern. The Independent Barents Observer quoted the Minister as saying, in an interview with RIA Novosti, he feared the thawing permafrost would undermine the stability of Arctic infrastructure and increase the likelihood of dangerous phenomena like sinkholes. Russia has important oil and gas installations in Arctic regions. Clearly, any damage would have considerable economic implications. There are also whole cities built on permafrost in the Russian north.
High time to adapt
In 2014, I interviewed Hugues Lantuit, a coastal permafrost geomorphologist with the Alfred Wegener Institute for Polar and Marine Research, about an integrated database on permafrost temperature being set up as an EU project. He told me it would be very hard to halt this permafrost thaw, and stressed that permafrost underlies 44 percent of the land part of the northern hemisphere.
“The air temperature is warming in the Arctic, and we need to build and adapt infrastructure to these changing conditions. It’s very hard, because permafrost is frozen ground. It contains ice, and sometimes this ice is not distributed evenly under the surface. It’s very hard to predict where it’s going to be, and thus where the impact will be as the permafrost warms and thaws”.
I remember being shocked to see that people in Greenland were having to use refrigeration to keep the foundations of their buildings on permafrost stable. The scale of the problem is clearly much greater in cities like Yakutsk.
Then, of course comes the feedback problem, when thawing permafrost releases the organic carbon stored within it. Let me give the last word to Hugues Lantuit:
“This is a major issue, because it contains a lot of what we call organic carbon, and that is stored in the upper part of permafrost. And if that warms, the carbon is made available to microorganisms that convert it back to carbon dioxide and methane. And we estimate right now that there is twice as much organic carbon in permafrost as there is in the atmosphere. So you can see the scale of the potential impact of warming in the Arctic.”

Paris: A COP-out for Arctic Peoples?
As I write, the climate negotiations have been extended into Saturday. Same procedure as every year? While I still hope the seemingly never-ending bickering will result in a document which will at least signal the end of the fossil fuels era, I cannot help feeling a sense of sadness and regret, that this is all way too late for the Arctic, as I discussed in the last blog post. And I wonder how all this feels to indigenous folk living in the High North, as they see their traditional lifestyles melting away.
On a recent edition of DW’s Living Planet programme, Lakeidra Chavis reported on the effect of melting permafrost on indigenous communities in Alaska. Chatting to a colleague in between times about the story, she told me how moved she was to hear how skulls had been washed up in a river as the permafrost at a burial site thawed.
Climate change impacts the present, future – and past
I had a kind of déjà vu feeling. Back in 2008, in those early days of the Ice Blog, I travelled out to Point Barrow, the northernmost point in the USA, with archaeologist Anne Jensen. We visited the site where a village had had to be re-located because of coastal erosion, with melting permafrost and dwinding sea ice. She told me how she was called up by distraught locals in the middle of the night and asked to help recover the remains of their ancestors before they were washed into the ocean. My colleague here in Bonn was surprised to hear that I had conducted that interview back in 2008. How could this have been known at that time already, yet so little publicized?
Victims or culprits?
While a lot of attention is focused (and rightly so) on the impacts on developing countries, Asia, Africa, rising sea levels, this is an issue a lot of people know very little about. In an article for Cryopolitics Mia Bennet puts her finger on an interesting aspect of all this. The Arctic indigenous peoples are living in industrialized, developed states. That gives them an interesting status, somewhere between being victims and perpetrators of climate warming.
“A discourse of victimization pervades much Western reporting on the Arctic”, she writes. A lot of people in the region tend to blame countries outside the region for climate change. She quotes a study in Nature Climate Change in which researchers found that emissions from Asian countries are the largest single contributor to Arctic warming. But she notes that gas flaring emissions in Russia and forest fires and gas flaring emissions in the Nordic countries are the second two biggest contributors. And these industries are often supported by locals, not least because of the jobs and prosperity they bring.
This brings me back to some encounters I had during that trip to Alaska in 2008 – and others since, with Inuit people employed in the oil sector. They were reluctant to accept that the industries that provided their livelihoods could ultimately be literally eroding the basis of their cultures. Russia, the USA, Canada, Norway – are all countries involved in oil and gas exploitation. Some northern regions are highly dependent on the industries which are warming the climate.
“And for their part, Arctic countries must realize that reducing emissions begins at home on the region’s heavily polluting oil platforms and gas flaring stacks – not in Paris”, says Mia Bennet.
All up to Paris?
The sad truth is that even the two-degree target – or the 1.5 currently being debated – will not have much of an impact on Arctic warming.
Mia Bennet puts it bluntly. “Regardless of whether a positive or negative outcome is reached in Paris at COP 21, it will not dramatically affect the Arctic.”
A delegation of indigenous leaders from the Arctic countries is in Paris at the talks. Both the Inuit Circumpolar Council and the Saami Council have sent delegates, with the aim of highlighting the consequences of a warming climate for the polar regions.
Council representatives are from three distinct Inuit regions: Canada, the USA and Greenland. The Chukotka region of Russia also has a substantial Inuit population, who are not directly represented in Paris, but belong to the Council. The Saami Council has representatives from Finland, Russia, Norway and Sweden. Both sets of delegates are attending as observers, without voting rights.
In a position paper, Inuit Circumpolar Council Chair Okalik Eegeesiak of Canada stresses the Inuit’s deep concern about the impacts of climate change on their cultural, social and economic health.
She describes the Arctic’s sensitive ecosystem as a “canary in the coal mine for global change”. Following that metaphor, the canary must be close to suffocating.
The Inuit representatives in Paris are appealing for stronger measures to keep global temperature rise below 1.5 degrees C. They stress that the land and sea sustain their culture and wildlife, “on which we depend for food security, daily nutrition and overall cultural integrity”.
But ultimately, in a world where altruism seldom plays a part, it may be their other argument – the role of the Arctic in influencing the global climate system – that convinces negotiators of the need to work against global warming. With increasing knowledge and awareness of the extent to which the Arctic influences global processes and thus weather and climate all over the globe, the willingness to take measures to prevent further deterioration of the cryosphere is likely to increase. Whether it will be in time is another question. Any negotiator in Paris who has taken a brief moment off to read this – remember, we are not talking about a remote region with a small population. We are all in this together.

Ice Blog readers may remember the story of the two ice researchers and polar explorers who died when they broke through unexpectedly thin ice in the Canadian Arctic earlier this year. This week I had the chance to join friends and admirers of Marc Cornelissen and Philip de Roo at a ceremony held in their home country, the Netherlands. The unusually warm November weather, with people sitting out eating ice cream, seemed oddly apt for a tribute to two people who died doing climate research.

Arctic investment: still a hot prospect?
As I mentioned in the last post, I talked to various people about the current state of interest in the Arctic, in connection with the ArcticNet conference on “Arctic Change” in Ottawa last week. I would like to share some of the insights I gained with you here on the Ice Blog. With a lot of concerned people still suffering from a kind of mental hangover after the two weeks of UN climate negotiations in Lima, let me also direct you to a commentary I wrote for DW: Lima: a disappointment, but not a surprise. If you expected any action at the meeting which might help stop the Arctic warming, you will have been highly disappointed. If, like me, you think the transition to renewables and emissions reductions we need have to happen outside of and alongside that process, all day and every day, your expectations will not have been so high.
But back to the Arctic itself. With Canada coming to the end of its spell at the helm of the Arctic Council and preparing to hand over the rotating presidency to the USA at the end of the year, the annual conference organized by the research network ArcticNet was bound to attract a lot of interest. More than 1200 leading international Arctic researchers, indigenous leaders, policy makers, NGOs and business people attended the Ottawa gathering to discuss the pressing issues facing the warming Arctic.
Hugues Lantuit from Germany’s Alfred Wegener Institute is a member of the steering committee. He’s an expert on permafrost and coastal erosion. He told me in an interview that the region had to prepare for greater impacts ,with the latest IPCC report projecting the Arctic would continue to warm at a rate faster than any place on earth. While the retreat of sea ice allows easier access for shipping and more scope for commercial activities, Lantuit is concerned about the thawing of permafrost, a key topic at the Ottawa gathering:
“An extensive part of the circumpolar north is covered with permafrost, and it’s currently warming at a fast pace. A lot of cities are built on permafrost, and the layer that is thawing in the summer is expanding and getting deeper and deeper, which threatens infrastructure.”
Northern communities worried
Residents of northern communities are concerned about the impact of melting permafrost on railways, landing strips and buildings. Lantuit and his colleagues have created an integrated data base for permafrost temperature, with support from the EU. At the Ottawa meeting, he and his colleagues worked on identifying priorities for research, taking into account the needs of communities and stakeholders in the Arctic.
Another key issue on the Ottawa agenda was coastal erosion. Sea ice acts as a protective barrier to the coast, preventing waves from battering the shore and speeding up the thaw of permafrost. With decreasing sea ice in the summer, scientists expect more storms will impact on the coasts of the Arctic. “In some locations, especially in Alaska, we see much greater erosion than there was before”, says Lantuit. This creates a lot of issues: “There is oil and gas infrastructure on the coast, villages, people, also freshwater habitats for migrating caribou, so the coast has a tremendous social and ecological value in the Arctic, and coastal erosion is obviously a threat to settlements and to the features of this social and economical presence in the Arctic.”
Bad news for furred and feathered friends
Amongst the participants at the conference was George Divoky, an ornithologist who has spent every summer of the past 45 years on Cooper Island, off the coast of Barrow, in Arctic Alaska. Divoky monitors a colony of black guillemots that nest on the island in summer. His bird-watching project turned into a climate change observation project as he witnessed major changes in the last four decades:
“Warming first aided the guillemots (1970s and 1980) as the summer snow-free period increased. The size of the breeding colony increased during the initial stages of warming. Continued warming (1990s to present) caused the sea ice to rapidly retreat in July and August when guillemots are feeding nestlings, and the loss of ice reduced the amount and quality of prey resulting in widespread starvation of nestlings.”
The 2014 breeding season on Cooper Island had the lowest number of breeding pairs of Black Guillemots on the island in the last 20 years, Divoky says. Reduced sea ice is increasingly forcing polar bears to seek refuge on the island, eating large numbers of nestlings. Polar bears were rare visitors to the island until 2002.
The Arctic and the global climate
Divoky went to Ottawa to fit his research and experience into the wider context of climate impacts in the Arctic. Researching climate change and its effects are important but of little practical use if the research does not inform government officials and result in policies that address the causes of climate change, Divoky argues.
I asked Hugues Lantuit whether he thought the UN climate conference in Peru could achieve anything that would halt the warming of the Arctic. He said reducing emissions and reducing temperature were the only way to reduce the thaw of permafrost. But he is quite clear about the fact that there is no mitigation strategy in terms of permafrost directly. “You would have to put a blanket over the entire permafrost in the northern hemisphere. This is not possible.”
At the same time, he stressed the key role of the Arctic with regard to the whole world climate: “Permafrost contains a lot of what we call organic carbon, and that is stored in the upper part. And if that warms, the carbon is made available to microorganisms that convert it back to carbon dioxide and methane. And we estimate right now that there is twice as much organic carbon in permafrost as there is in the atmosphere”.
So far, the international community has not been able to take measures to break that vicious circle.
What happened to the Arctic gold rush?
Communities who live and companies that work in the Arctic have to focus on adaptation to the rapid change, says Lantuit. In his eyes, economic activity is increasing, posing new challenges for infrastructure and the environment.
Malte Humpert, the Executive Director of the Arctic Institute, a non-profit think tank based in Washington DC has a different view on the matter. He says while attendance at Arctic conferences and interest in the Arctic is still high, commercial activity has actually been cooling off. “We are seeing a slow-down of investment. Up to this point there has been a lot of studying, a lot of interest being voiced, with representatives from China or South Korea, Japan, Singapore or other actors, arriving at conferences, speaking about grand plans. But up to this point a lot of the talk has been just that.” A lot of activity has been put on hold, says Humpert. He says the “gold rush mentality we saw a few years ago” has weakened. “There was a lot of talk about Arctic shipping initially, then we had oil and gas activity in 2012, north of Alaska, then we had the discussion about minerals in Greenland. The question is now, with the oil price being down below 70$ a barrel, some political uncertainties over the Ukraine, involving the EU and Russia, how will that affect Arctic development?”
Humpert stresses the Arctic does not exist in a vacuum, but has to be seen within the global context. Sanctions on Russia because of the Ukraine crisis have created economic problems for Moscow and limited access to technology it might need for its Arctic activities. “Maybe Arctic development has been oversold and overplayed and will be more of a niche operators’ investment. One could definitely question if there will be this global push into the Arctic.”
Arctic development on ice
Humpert is skeptical that any major development will take place before 2030. He says developing the infrastructure in terms of ports and communications in the remote Arctic region would require billions of dollars of investment, and would have to be a very long-term proposition. It will also depend to a large extent on exactly how climate change affects ice conditions in the Arctic. Climate change can make the climatic conditions in the Arctic more variable. This means that for a temporary period, there might even be more ice, which would block transport routes.
The Arctic Institute says there has actually been a slow down this year in terms of navigation on the northern sea route (NSR) in particular: “The season just closed about a week ago. Last year we had 1.35 million tonnes of cargo being transported along the NSR, this year we had less than 700,000 tonnes, so an almost 50% decrease, just because there was more ice in the way”, says Humpert.
Whether slower development is good news or bad depends on your perspective. The lull in Arctic activity could pre-empt environmental degradation or destruction, says Humpert, and leave scope to consider development of the Arctic in what he calls a 21st century way. Instead of “old-school” thinking about extracting minerals, oil and gas and increasing shipping, there could be a focus on bringing modern, high-speed communications, fiber optics and thinking about renewables, such as wave energy. This would benefit the small populations in the Arctic, the expert argues.
But from the viewpoint of a country like Russia, he adds, where 40 percent of your exports are generated above the Arctic circle, in terms of hydrocarbon resources, the slowdown in Arctic development because of the drop in oil prices and political tensions over Ukraine is very worrying.
So while these developments seem to have brought the Arctic a breathing space, ultimately, the commercialization of the region could be just a matter of time. Ottawa conference organizer Lantuit argues that there has always been activity in the high North. The priority now, he says, must be to ensure international cooperation and additional investment in protecting the environment and maintaining safety in a region where rapid change seems to have become the status quo.
