Changing Climate, Changing World
Changing shades of ice at 2am
I just read an advertisement for “mobile tourist cabins”. The main advantage listed is that you can move them around to cope with climate change, so that you can shift them with the ice sheet as it retreats.
Climate change is very obvious here, although I’ve met a few people who still think it could be just natural fluctuation. Some of them are people in the tourist industry. Jens Laursen, the manager of tourism in Kangerlussuaq is unwilling to accept a connection between emissions from air travel and retreating ice. He is, of course, dependent on people coming to Greenland by air. Flying is the main way to get anywhere here, and the distances are huge on the world’s biggest island. In winter, dogsled has traditionally been the main means of transport, not only for personal use, but for instance for fishermen, who bring large quantities of halibut they catch by a long line dropped through holes in the ice over the snowy slopes to Ilulissat. But this is losing importance, as the season when there’s enough hard-packed snow for it to be viable is becoming shorter, and the winters become less predictable.
Accounts from the locals here back up what the scientists are telling us. Morten Rasch, the man behind the Zackenberg ecological monitoring programme, for example, stresses that the variability of the climate will increase. Yesterday I interviewed Karen Filskov, who comes from Ilulissat and now works for Destination Avannaa -the regional office promoting development in the huge region of North Greenland, Qaasuitsup kommunia. It’s said to be the biggest municipality in the world in terms of area, with 660,000 km2. She told me a series of winters in a row up to 2006 had been so mild the fishermen could fish from boats in the bay rather than taking the dogsleds to the ice. A lot of them then got rid of their dog teams, which are expensive to feed. Then the last two winters were particularly harsh. The water was frozen, and they had no dogs. It’s becoming increasingly changeable, she says.
Karen told me there are still 3,000 dogs in Ilulissat. Most of them now have to be kept outside the town centre – admittedly not far away. There’s a weird rugged rocky area dotted with little dog kennels and huskies – chained so they don’t run around fighting in packs – dozing in the heat beside their sleds.
The captain of the “Pearl”, a boat that takes people to see calving glaciers up the coast, told me he had not only noticed differences in his work on the water. He used to travel around, for instance to matches with his local football team, using the dogsled in winter. Now, he says, he can only rely on that for a few weeks rather than a few months. Incidentally, I talked to him with the assistance of Laali Berthelsen from Nuuk, the capital of Greenland.
She’s working here as a guide in between her studies. She’s one of the few people here who seems to have recognised the potential of learning languages and the tourism industry. Most of the people working as guides here are from Denmark or other European countries. It seems there’s still a lack of locals with the necessary language skills. Nowadays, the children (and there are plenty of them here) are learning English at an early stage in school, so perhaps the next generation will be different.
Laali also told me she used to get new skis every Christmas as a child in Nuuk. These days she has to go somewhere else if she want’s enough snow to ski.
Ilulissat’s glacier, Sermeq Kujalleq (Jakobshauen) and the ice fjord (Kangia) are striking witnesses to the process of global change (assuming you know what they were like before, that is).
The glacier discharges ice from the inland ice sheet into the sea. The pieces that break off are stranded in the fjord, where the water is fairly shallow, resulting in the spectacular jam of icebergs, some smooth, some jagged, over kilometres, right down to the mouth at Ilulissat. But the glacier itself has retreated massively, especially since 2001. Karen tells me the icebergs are smaller (although still huge), because the ice is also thinner.

“Global Contact” in the Town on the Icefjord
Ilulissat was once a small trading post. Nowadays it has 4,500 inhabitants, and the number is growing rapidly.
You can smell fish in quite a few parts of the town. Fishing is the number one industry
It happens on a commercial scale, particularly for halibut and shrimps. The town has a shrimp processing factory. The fish factory has moved further south, and people tell us the trend is increasingly towards factory ships, which process the fish as they’re caught.
Administration is the 2nd biggest employer. Ilulissat is the centre for a huge area around it, going right up to Quanaag in the far north. Tourism is the 3rd factor. It’s growing, but currently suffering from the world economic crisis. There are actually very few tourists in the town right now. The town still feels like boom-town, and the civil engineer tells me all the building work is the rush to build new houses for the growing population in the very short building season, before everything has to stop for the winter in October.
Ilulissat’s main attraction are the icebergs, floating in the fjord after breaking off from the Kangia glacier or Jakobshauen, which was the Danish name for it and the town. This is the most “productive” glacier in the northern hemisphere, discharging ice from the inland ice sheet into the sea at a tremendous rate. More about that later. The constantly changing panorama of icebergs of all different shapes and sizes creates the very special identity of Ilulissat.
The icefjord was added to UNESCO’S World Heritage List in 2004 because of its dramatic beauty and its unique glaciological characteristics. The organisation has now opened an office in the town that keeps an eye on it and supports measures to protect it – with a little help from friends like the volunteers brought here by a group called MS.
Lars from Germany and Martin from Switzerland are two of a group of 10 young people spending their summer holidays as volunteers here. They’ve helped organise a traditional music festival in one of the remote northern towns. Now they’re helping Naja Habermann, who runs the UNESCO office, to mark the hiking paths – like the one that took me along the ice fjord yesterday – which help people appreciate the natural beauty of the region without having too much of an impact on the countryside. These are the people who spend the day walking the paths and painting the markers. More power to you folks!
Mellemfolkeligt Samvirke, “ms act!onaid denmark” is the ngo that brings them here, with its “global contact” programme. They come from a variety of European countries. When I asked them why they do it, Lars and Martin both told me they want to do something more meaningful than lie on a beach all summer, and they’re keen to get to know other peoples and cultures. They also see it as a unique opportunity to get to a remote region of the world they would otherwise fail to see. I asked them whether climate change was important to them, against the background of this glacier discharging icebergs at an increasing rate. While they both said this hadn’t been their reason for coming here, they are very concerned about what’s happening and feel strongly the industrialised west should reduce emissions and its footprint. Talking to young people in Greenland, they found it interesting to hear a different view here. Awareness of the problems is not so high – and some of the people they talked to were happy about being able to grow more food in southern Greenland.
Caroline (right) and Sisse are coordinating the project, both here on a voluntary basis. They’re committed to promoting intercultural dialogue and bringing young people from different backgrounds together to work on projects like protecting the world’s heritage.
“It’s a dog’s life” in Ilulissat. Sled dogs have enforced holidays at least until October.

On the Greenland Ice Sheet
I have been walking on the world’s 2nd largest ice sheet. It would take 30 days to cross it on foot and skis, and it’s almost 3 kilometres thick at its thickest point. It’s hard to imagine that much ice. And to imagine what it would mean for the world’s oceans if it melted. A disastrous 7m rise is the most common estimate, and views on whether or when that might happen vary widely. It’s a complex process, with a lot of uncertainty. But the Greenland ice cap is undoubtedly losing mass overall. And the IPCC predictions have been well overtaken by the current rate of global change.
I drove to the inland ice from Kangerlussaq in a four-wheel drive vehicle. The road was actually financed by the German car company Volkswagen. They decided around 1999 to build a test area for their vehicles on the ice, and this was the access road. (Seems surprising to get permission to build a car test track across the ice sheet in the national park, but there you are).VW stopped in 2005, so did maintenance it seems. Still, with that and the old US base, people have been telling me this area has the most roads in Greenland.
It’s a gravel and sandy track, but 2 hours take you out to the ice and there are spectacular views on the way.(Also muskox and reindeer, but that’s not our subject today).
This is a view on the approach.
It’s strange – the sudden contrast, how Greenland changes from being literally green to icy blue-white:
A wall of ice.
At the end of the track, we walked up the morane, gravel discarded by the ice, and down the other side to get onto the ice sheet. It’s now 40 metres lower than it was when the road was built.
Once on the ice sheet, it’s ice as far as the eye can see.
It’s no wonder this is becoming a tourist attraction, although the remoteness of northern Greenland and the trouble and expense of getting here make sure it’s not a destination for mass tourism. But all the guides and tourist people I’ve spoken to confirm that the talk about climate change is attracting more people.
Some say it’s just that people are becoming more aware of the beauties of the Arctic. One guide was convinced a lot of visitors want to see the ice before it dwindles or disappears. It would certainly take a lot to melt this one. But the process appears to be in motion.

The Greenland Ice Blog
Greenland is a key area in the global climate process. The Greenland Ice Sheet is the largest body of freshwater ice in the northern hemisphere. In recent years it has become very clear that global warming is causing the ice sheet to lose mass. Increased melting and ice discharge would have major consequences for global sea level. The warming climate is also already having a considerable impact on the lifestyle of the people of Greenland.
During the next few weeks the Ice Blog will be written from an expedition to Greenland, beginning with a visit to Zackenberg Research Station in remote North Eastern Greenland. Zackenberg is an ecosystem research and monitoring facility at 74°30’N/21°W. The station is owned by the Greenland Home Rule and is operated by the National Environmental Research Institute.
The Ice Blogger will also be visiting the interior ice sheet and the coastal glaciers, finding out first hand about the work of scientists monitoring climate change and its effects, the latest research results, and the implications both for the people of Greenland and for the rest of the world.
Deutsche Welle’s Ice Blog is part of an international broadcasting collaboration to mark the International Polar Year, partly founded by the National Science Foundation. I am extremely grateful to the NSF, Moira Rankine of Soundprint Media Inc. USA who coordinates the international project and my own organisation Deutsche Welle for making all this possible.

Glaciers melting twice as fast as in 80s and 90s
(Kongswegen glacier, Svalbard, 2007)
The World Glacier Monitoring Service is based at the University of Zurich in Switzerland. Their latest summary of results indicates the world’s glaciers are continuing to melt rapidly. The Alps are particularly badly hit, with a much faster melting rate than the world average.
WGMS scientist Michael Zemp says 2007 was the 6th year this century with glaciers losing an average of more than half a metre of ice. This means the melting rate has doubled, he says, in comparison with the 1980s and 90s.
The WGMS Director is one of the world’s leading glacier experts. This background info. is worth a read, if you are interested in glaciers and how the information is collected:
