Arctic winter: warm, wet, weird
Here in Germany, the winter has seemed strange enough. We had flowers in bloom at Christmas, and people sneezing with pollen allergies. Overall it was extremely mild. Now we are just having the odd flurry of sleet, with the magnolias getting ready to bloom and much of nature said to be three weeks ahead of schedule. But that is nothing compared to what’s been going on in the Arctic.
“The Old Normal is Gone”, is the headline of a piece on Slate by Eric Holthaus, sub-headed “February Shatters Global Temperature Records”. He says the record warmth is so dramatic he is prepared to comment using unofficial data, before the official data comes out mid-March. February 2016, he says was probably somewhere between 1.15 and 1.4 degrees Celsius warmer than the long-term average, and about 0.2 degrees above last month, which was itself a record-breaker. This, Holthaus calculates, means while it took us from the start of industrialization until last October to reach the first 1 degree C. of warming, we have now gone up an extra 0.4 degrees in just five months. Paris target 1.5 degrees maximum – here we come!
In the Arctic, this is particularly dramatic. Parts of the Arctic were more than 16 degrees Celsius warmer than “normal” for the month of February, which, Holthaus says, is more like June temperatures, although it would normally be the coldest month.
Svalbard, one of my favourite icy places, has averaged 10 degrees Celsius above normal this winter, with temperatures rising above the freezing mark on nearly two dozen days since December first.
Correspondingly, the Arctic sea ice has reached a record low maximum. Lars Fischer, writing in the German publication Spektrum der Wissenschaft, notes that January already saw the smallest ice growth of the last ten years. In mid-February, he writes, satellite data showed the ice cover in some parts of the high north was almost a quarter of a million square kilometers less than ever before on this date. This lasted two weeks, than the ice grew a little last week, to draw equal with the previous all time low for a first of March. New ice will be much thinner than the old multi-year ice, a trend that has been increasing.
New satellite data
Researchers are using a new technique to gain data about the thinning ice pack in real time. An article in Nature, “Speedier Arctic data as warm winter shrinks sea ice”, describes a new tool to track changes as they happen and provide near real time estimates of ice thickness from the European Space Agency’s CryoSat-2 satellite. Previously, there was a time lag of at least a month.
Natural fluctuation, el Nino or human-made climate change?
Of course there are those who say fluctuation is natural in the Arctic. But this year, this fluctuation is extreme. Some researchers say the melt season started a whole month too early. Certainly, at this time, the Arctic should be in the grip of winter.
Fischer titles his article “Absurd winter in the Arctic”. I’m not sure absurd is the best way of describing it. (It could actually seem quite logical if you look at the extent of extra warmth we have been creating with our greenhouse gas emissions). Looking at an article in the Independent by Geoffrey Lean, I see the term “absurdly warm”comes from the NSIDC, National Snow and Ice Data Centre in Boulder, Colorado. The “strangest ever” and “off the chart” are used by NSIDC director Mark Serreze and NOOA respectively. Those figure.
In December 2015, the high Arctic experienced a heatwave. We saw temperatures near the North Pole going above freezing point. January was the warmest month since the beginning of weather data. In February, parts of the Arctic were more than ten degrees warmer than the long-term average.
The Arctic Oscillation is partly to blame. It is currently such that warm air can make its way north. Strong Atlantic storms have been pressing the warm, moist air north into the High Arctic. But surely there can be no doubt that our human-made climate warming is playing a major role in all this?
It remains to be seen how the situation will develop as the spring sets in. Fisher notes that the last winter ice maximum extent was very low, but was not followed by a new record low in summer.
Eric Holthaus notes that although we are experiencing a record-setting El Nino, which “tends to boost global temperatures for as much as six or eight months beyond its wintertime peak”, this alone cannot be responsible for the temperature records.
He quotes scientific studies indicating that El Nino’s influence on global temperatures as a whole is likely small, and that its influence on the Arctic still isn’t well known.
“So what’s actually happening now is the liberation of nearly two decades’ worth of global warming energy that’s been stored in the oceans since the last major El Nino in 1998”, he writes.
“The old normal is gone”
Whatever the cause – this record warmth is a major event in our climate system. Holthaus quotes Peter Gleick, a climate scientist at the Pacific Institute in Oakland, California in his article title: “The old normal is gone”. “The old assumptions about what was normal are being tossed out the window”.
“We could now be right in the heart of a decade or more surge in global warming that could kick off a series of tipping points with far-reaching implications”, says Holthaus. Where have I heard this before?
Lean, in the independent, says two new studies by the Woods Hole Research Center in Massachusetts give new evidence of self-reinforcing feedback mechanisms. This is not new. How much more evidence do we need? Permafrost thaws, resulting in emissions of methane and CO2 from the soil. Melting ice means the reflective white surface is replaced by dark water, which absorbs heat.
So what are we doing about it? In interviews with experts from NGOs including Earthwatch and Germanwatch recently, various experts have been confirming my own feeling that the Paris Climate Agreement may have been a milestone, but not necessarily a turning point – unless climate action is taken very quickly.
I would like to be optimistic. But there is so much evidence suggesting that whatever we do, it is likely to come too late to save the Arctic as we know – knew – it for coming generations. Come on world, prove me wrong! Please!

Arctic Winter Impressions
Your Iceblogger is off on a hard-earned break for the next few weeks. I’d like to leave you with some photographic impressions of my winter trip to the Arctic. Thanks again to Norway’s Arctic University in Tromso and the organisers of Arctic Frontiers for the opportunity to visit Svalbard and Tromso at this fascinating time of year. Look out for the next post in April, when spring should be well underway.

Norway’s Polar Satellite Centre
Polar orbit satellites monitor what’s happening at the ends of the planet – and, of course, the regions in between. Ice conditions, land movement, shipping, pollution – but how does that information actually make its way to the scientists and authorities who evaluate it and use it as a basis for all kinds of decisions?
During my recent visit to Arctic Norway, I had the chance to visit a facility that plays a key role in collecting and disseminating satellite data on the polar regions. On the outskirts of Tromso, Norway’s “Gateway to the Arctic”, there is a satellite ground station, run by KSat, or Kongsberg Satellite Services AS. It is a Norwegian commercial company which provides ground station and earth observation services for polar orbiting satellites. With three interconnected polar ground stations: Tromsø at 69°N, Svalbard (SvalSat) at 78°N and Antarctic TrollSat Station at 72°S, combined with a mid-latitude network of stations in South Africa, Dubai, Singapore and Mauritius, KSAT operates over 70 antennae positioned for access to polar and geostationary orbits.
The Tromso station has contact to 85 satellites every day, and every month the station monitors some 15,000 passes of these satellites overhead.
When it comes to which businesses stand to gain from climate change, the providers of satellite data have to rank high on the list. There is a huge demand for data from space, and KSat, it seems, is the biggest company worldwide carrying out this kind of activity.
While I was in town for the Arctic Frontiers conference, two colleagues and I were shown the facility on a beautiful wintry Saturday morning by Jan Petter Pedersen, the Vice President of the company, who is responsible for developing products to expand the business. He studied physics in Tromso and got into satellites during that time, he told us, going on to a PHD in remote sensing. Pedersen has been at KSat for 20 years and says the technology has come a long way in that time. These days, it’s all about remote control via pcs.
We tend to take satellite data for granted. But if you think about it, somebody has to pick up the masses of data from all those satellites circling over the poles and pass the appropriate images to those who need them. Energy, environment, security – these are key areas which make use of the data. In the Tromso station, that data is provided to those who need it more or less in real-time. The company says it can get the data down and sent on to its destination anywhere in the world within 20 minutes. So if you want to detect an oil spill in – say – the Gulf of Mexico? – The chances are, you will get information from this Arctic town.
Some companies own and operate their own satellites, and distribute the data. KSat doesn’t own any satellites, but has agreements to use data. They can access radio data from almost all satellites in operation today.
The USA and Canada are the biggest market for the company’s services, says Pedersen. Then comes Europe, followed by Asia.
The world’s largest polar ground station is the one on the Arctic island of Svalbard. I wasn’t able to visit it during my winter trip – put it must be pretty impressive, with more than 30 antennae.
Satellite monitoring as deterrent to polluters?
When it comes to oil spill detection or monitoring, satellite images play a key role.
Optical sensors have limitations in bad weather, so radar satellite data are of key importance, Pedersen explains. Oil spill detection is the most important of KSat’s earth observation activities. EMSO (European marine Safety Agency) in Lisbon is responsible for European oil spill detection. They get satellite data from 4 providers of satellite data, of which KSat is the biggest. It covers 60% of the waters from the Barents Sea to the Bay of Biscay and the Baltic.
In 2008 there were 10.77 possible reported spills per million km2. In 2011, this was down to 5.08, Pedersen told us. I asked why they talk of “possible”. It seems it is not always possible to be 100 percent sure what the satellite detects is an oil spill. The reliability is somewhere over 60 percent. Pedersen believes the satellite service plays a role in decreasing the figure. As it becomes increasingly well known that satellites are observing and collecting the data, there is a higher awareness that oil spills are being detected. Presumably this is a deterrent to deliberate discharges of oil as well as a key source of information on accidents.
From pirates to icebergs
Another key use for satellite data is in monitoring ship traffic, including detecting, tracking and identifying vessels. This means the authorities can spot illegal activities and inform the coast guards. This helps in finding pirates, for instance.
Tracking icebergs and monitoring ice development have also been aided by the growing availability of satellite data. The NSIDC is one of KSat’s most important customers. They need the data to map the extent and condition of the ice.
Ships frozen into the ice for research purposes such as the Lance, use satellite images via Tromso. Many other ships use them to chart a course when operating in ice.
Monitoring fishing activities, offshore oil exploration, tracking land movement – all these activities rely on satellite information today.
Pedersen told us the Norwegian capital Oslo is sinking at a rate of 2 cm a year. He also mentioned a landslide risk area outside of Tromso, where a mountain is sliding into the ocean. Ultimately, it will go into the fjord and create a tsunami effect, says Pedersen. That would endanger the settlement. It is moving at 15mm per year. The satellites are keeping an electronic eye on it.
Norway, incidentally, is the country with the highest use of data per person. Most of it is maritime. So it seems fitting that the country should be the location of some of the world’s most important ground stations. There is more to the picturesque Arctic harbour town of Tromso than meets the eye – I can tell you that even without satellite data!

Obama stops oil in Arctic Wildlife Reserve
Back in Germany after spending a week and a half on the RV Helmer Hanssen off the coast of Spitsbergen, and then in Norway’s Arctic capital Tromso at Arctic Frontiers, I thought I might be in for a shock on my return to warmer climes and a news agenda focusing on stories non-Arctic. Instead, I found some continuity both in the weather and the media. A heavy fall of snow here kept the Arctic feeling alive, while a twitter of messages on Sunday carried on the lively debate that was happening at Arctic Frontiers over the pros and cons of oil drilling in the Arctic.
The Washington Post broke the story about President Obama proposing new wilderness protection in the Arctic National Wildlife Refuge (ANWR). “Alaska Republicans declare war” was the second part of the headline. Clearly, emotions are running high.
The Obama administration is proposing setting aside more than 12 million acres of the Arctic National Wildlife Refuge in Alaska as wilderness. This stops – at least for the moment – any prospect of oil exploration in an area which has long been the subject of controversy between those who say environment protection should be the number one priority and those who say finding oil is more important.
“Alaska’s National Wildlife Refuge is an incredible place – pristine, undisturbed. It supports caribou and polar bears, all manner of marine life, countless species of birds and fish, and for centuries it supported many Alaska Native communities. But it’s very fragile”, the President says in a White House video about the proposals.
It seems this is only the first of a series of decisions to be made by the Interior Department relating to the state’s oil and gas production during the coming week. The Washington Post says the department will also put part of the Arctic Ocean off limits to drilling, and is considering whether to impose additional limits on oil and gas production in parts of the National Petroleum Reserve in Alaska.
Only the US Congress can actually create a wilderness area, but once the federal government has designated a place for that status, it receives the highest level of protection until Congress acts. “The move marks the latest instance of Obama’s aggressive use of executive authority to advance his top policy priorities”, writes Juliet Eilperin in the Washington Post.
The ANWR holds considerable reserves of petroleum, but is also a critical habitat for Arctic wildlife. Senator Lisa Murkowski from Alaska is the new chairman of the Senate Energy and Natural Resources Committee. Unsurprisingly, she is set to fight the Obama decision. The Governor of Alaska, Bill Walker, issued a statement saying he might have to accelerate giving permits for oil and gas on state lands to compensate for the new federal restrictions.
Can the fate of an area of such key ecological importance really be reduced to a good to be bargained for in a political tit-for-tat?
Conservation groups were over the moon about the Obama move. “Some places are simply too special to drill, and we are thrilled that a federal agency has acknowledged that the refuge merits wilderness protection”, said a statement from Jamie Williams, president of the Wilderness Society.
But apart from the danger of an oil spill and the threat to the habitat of Arctic species, we have to come back to that Tromso conference theme of Climate and Energy. The Arctic is being hit at least twice as fast as the global average by climate change. The ecosystem is already under huge pressure. The Arctic itself is of key importance to global weather patterns. And burning more oil would exacerbate the situation even further. I am reminded of the argument put forward by Jens Ulltveit-Moe, the CEO of Umoe, himself a former oil industry executive. Apart from the fact that the current low oil price means the Arctic oil hunt is too expensive, if the world is serious about emission cuts to halt climate warming, there is no need for and will be no demand for oil from the Arctic in coming decades.
That is something to be kept in mind as the debate in the USA continues over that precious piece of land and sea that is the ANWR.

Climate worry grows at Arctic Frontiers
I have followed the past two days, the political section of the Arctic Frontiers conference, with great interest, with the thought of the Paris climate conference in November always at the back of my mind.
Clearly, in a country rich from the sale of oil, cutting climate-killing emissions is a tricky issue. The oil sector was strongly represented here, but so too were those who see the need for a transition away from fossil fuels in the interests of the global climate.
With climate change opening the Arctic to development and the search for the oil, gas and minerals thought to be locked beneath the icy region, this year’s Arctic Frontiers meeting has attracted record participation. The impact of low oil prices on development prospects, and political tensions between Russia and western Arctic states have heightened interest in listening to what experts and decision-makers have to say on the relation between climate and energy.
With prime ministers from Norway and Finland and other ministers from Sweden and Denmark, as well as the US special Representative for the Arctic and the Russian President’s special representative for international polar cooperation addressing the meeting, media interest is high in this Arctic city, two hours flight north of the Norwegian capital, Oslo. (Looking at my flight schedule, I see Oslo is actually closer to Frankfurt than to the Arctic north of the country).
Do we need Arctic oil in a warming world?
The Norwegian premier Erna Solberg was here for the presentation of a report on sustainable growth in the north, a joint venture by Norway, Sweden and Finland. Gas is one of the four drivers named in the report. She left no doubt about her country’s continuing interest in oil and gas exploitation in the Arctic region. She told me in a brief interview she sees no contradiction between this and attempts to reach a new world climate agreement in Paris at the end of the year:
“’We have an oil and gas strategy. There are many not yet found areas where we think there is more gas. We think gas is an important part of a future energy mix, and I think we have to explore to find it.”
The same day, the Norwegian government allocated new licenses for exploration in the north-western Barents sea area of the Arctic. Many of the blocks released for petroleum licensing are close to the sea ice zone that had previously been protected. The zones have now been redefined. Conservation groups are upset. WWF Norway says the announcement is risky, as there is still a lack of knowledge about species and ecosystems in this area.
Will low oil price halt Arctic energy development?
With oil prices at a record low, environmentalists hope Arctic development will slow down or even be put “on ice” permanently. Representatives of WWF told the delegates in Tromso – including high-ranking representatives of major oil companies Statoil and Rosneft – the world does not need oil from the Arctic. And gas should be only a “transition fuel”. Samantha Smith, leader of the ngo’s Global Climate and Energy Initiative, quoted the recent study indicating that 50% of the world’s remaining gas and 30% of the oil must stay in the ground if the two degrees centigrade target for maximum global temperature rise agreed by the international community is to have any chance of being adhered to. She presented an alternative vision of “a thriving green economy in the white north”, with renewable energies replacing the search for oil and gas.
Business rethinking fossil investment?
As I wrote here on the Ice Blog after the Sunday evening opening, it is not only the environment lobby that is advocating a switch to renewable enerergy. Jens Ulltveit-Moe, the CEO of Umoe, one of the largest, privately owned companies in Norway, active amongst other things in shipping and energy, said with the current low oil price, Arctic oil was simply not viable, and this would remain the case for many years to come. And by then, he said, the EU’s climate targets and the international support for a two-degree target would make fossil fuels a non-option.
But Sjell Giæver, Director of Petroarctic and Tim Dodson, Norwegian Statoil’s Head of Global Exploration, insisted short-term price drops alone would not halt Arctic exploration. The region was the last place to discover large new reservoirs to satisfy continuing high demand for oil and gas for an increasing world population.
Oil ventures in the Arctic have not been particularly successful in recent years. Statoil’s Dobson admits the biggest ever exploration drilling programme in the Barents Sea last year had a disappointing outcome. Statoil and others have also withdrawn from the hunt for oil off the coast of Greenland.
Russia hungry for Arctic energy
But the Russian President’s Special Representative for International Cooperation in the Arctic, Arthur Chilingarov, who is also a Member of the Board of Directors at the Russian oil giant Rosneft, stressed the company had completed construction of the northernmost well in the world last September. He said a new oil and gas field has been discovered and the program of Rosneft for 2015 to 2019 provided for a large volume of prospecting and drilling in the western part of the Arctic.
One factor however that is slowing Russian activity the Arctic is the implementation of sanctions by European countries and the USA on account of the tensions over Ukraine. Russia has turned to China and other countries for help, but the lack of western technology is an obstacle to further development in a region where bad weather, ice, remoteness and complete darkness in the winter months make oil and gas development a risky business.
There is a clear tendency amongst those involved in Arctic cooperation to play down the sanctions and keep political tensions out of the region. Norwegian President Solberg told me: “We have a good relationship in the Arctic Council with Russia. We have said we will be in line with Europe on sanctions, although Norway is one of the countries hit most by the counter-sanctions from Russia, for instance the fact that oil and gas exploration are among the sanction areas.”
But in the meantime, on a day-to-day basis, cooperation continues, for instance in the joint management of fish resources, said Solberg.
Business as usual?
While the debate continued in the political section of Arctic Frontiers, a new, business strand of the conference opened in parallel. It focuses – on oil, gas and minerals. Olav Orheim from GRID Arendal, a centre that works with UNEP, stressed that a lot of people here are in favour of Arctic oil and gas exploration, in the interests of jobs and economic benefits.Yet after the publication of last year’s IPCC report and with climate change high on the international agenda, there seems to be a wider acceptance here in Tromso of the disconnect between burning fossil fuels and the ever more urgent need to reduce greenhouse gas emissions.
Gunnar Sand is Vice President of SINTEF, the Norwegian “Foundation for Scientific and Industrial Research”, which has close ties to the oil business. From a moral point of view, “we all want to stay below the two degree limit”, says Sand. But it is not possible to change a society and an infrastructure based on fossil fuels overnight.
Technical progress too slow to stop warming
Technology for renewable energy is still not developing fast enough, says Sand. Emission reduction scenarios also rely heavily on carbon capture and storage (CCS), which would reduce emissions from fossil fuel burning and bridge the transition to a low-carbon economy. But the technology, which he himself has been involved in, is moving too slowly. I first met him during a visit to Svalbard, when he told me about a carbon capture and storage project, designed to capture emissions from Longyearbjen’s power station underground. He confirmed in Tromso that it has never been put into action.
Global warming, Sand says, is the most serious challenge of our time. This has to be reflected in political priorities. Governments have to create economic incentives to speed up change.
US special representative ex-Admiral Robert Papp indicated dealing with climate change would be one of the key policy drivers when the USA takes over the Chair of the Arctic Council, the international body that coordinates Arctic affairs, in April.
The Chair of the US Arctic Research Commission Fran Ulmer says a carbon tax would be the best way forward, to encourage industry and consumers to save energy and cut emissions. But she acknowledged the reluctance of governments to impose decisions that could upset their voters at the next election. That is the reality we face as countries weigh up their pledges for the November climate conference in Paris.
