Alarming rise in Arctic methane emissions
Sound familiar? Ice-blog readers will remember methane is more than 20 times as powerful as CO2 as a greenhouse gas, and that scientists in the Arctic are measuring the extent of methane emissions from melting permafrost.
There are billions of tonnes of methane captured in the Arctic soil. As temperatures rise and the permafrost melts, more methane is released. It increases the greenhouse effect further, resulting in a “feedback loop”, with the increased warming melting more permafrost and releasing even more methane.
Zackenberg station in Greenland, which I visited this year, is one of the Arctic stations measuring methane. If you haven’t heard the programme I made including interviews with Prof. Morten Rasch, who heads the Greenland environment monitoring programme, it’s available under the “climate” banner on the right of DW’s environment page. There’s also a photo gallery with brief texts if you don’t have the time to listen to the full feature.
Climate Monitoring in Arctic Greenland
Now a study presented in the journal Nature reports a massive rise in the amount of methane being released from the Arctic permafrost.

Guardian’s David Adam on rise in Arctic methane emissions
Although only 2% of global methane comes from the Arctic, the increase is highest in the Arctic, which is warming much faster than the rest of the planet.
The Guardian quotes Prof. Paul Palmer from Edinburgh University as saying the study “does not show the Arctic has passed a tipping point, but it should open people’s eyes. it shows there is a positive feedback and that higher temperatures bring higher emissions and faster warming”.

Polar Bear at Zackenberg
I got a mail today from Lars Holst Hansen, deputy station chief during the summer season at Zackenberg Ecological Research Station, the one I visited in July, and a biologist with NERI, the National Environment Research Institute.
It seems there have been several polar bear visits to the station, right up on to the beach. Lars, many thanks for your short report. Here is one of Lars’ pictures.

You may well ask what a polar bear is doing on land like this at this time of the year, no ice in sight anywhere. Presumably he is hungry. It seems he also went close to some Zackenberg kayakers. I’m hoping Lars will send me the scientist’s view of the visit.
Thanks again Lars, and look forward to hearing more from you.

As we descended to the lake, I was surprised to see that the party waiting on the beach to be picked up was a different generation from the young scientists one tends to encounter in these remote and often trying areas. The two women and three men waving us in were, I discovered, the “British North East Greenland project”. Now retired, but lovers of the Arctic, they have all the necessary gear, bought special inflatable boats and come to this remote region every year for around 3 weeks, set up camp and go hiking, boating and collecting samples for various scientists. They had also made some archaeological finds. One of the ladies told me she had two artificial knees. She walked with a stick, but still managed to get up the ladder and into the twin otter, with a little help from her friends. More power to you folks, and if you read this when you get home, please put some info about your project onto the blog, and an email address where I can contact you, if you like. I think your project is great.
The group had their stuff all packed up, and I now found out why the front of the plane had been cleared.
The captain and co-pilot do everything on these routes, and we all helped get the equipment loaded onto the plane.
Once it was all inside, we just had to trust we wouldn’t need to reach that emergency exit.
Our next destination was Mesterswig, a Danish military aerodrome used, like Daneborg, as a drop-off and pick-up point.
My fellow travellers told me the government had been threatening to close it down for the last 20 years. With the latest resurge in military interest in the Arctic, it probably has a good chance of staying open.
The group has storage space in Mesterswig where they store their gear until next year. They’re well known and welcome. While they stowed it all, our copilot had a well-earned break on the runway. I wonder what insect repellent he uses. You can’t tell to look at him we were all under mega-attack from thousands of giant mosquitoes. (I’d have liked our Zackenberg insect experts Gergely and Tomas to have a look, but the only samples I have are somewhat squashed..)
From here, we headed down to Constable Point, for refuelling before we tackled the longer stretch to Iceland. (Flying from East to West Greenland goes, I’m afraid, via Iceland, there are few direct travel options). There were plenty more beautiful ice and snow views on route.This is a very spectacular part of the world.
We found the fire brigade waiting. We had been warned our captain would be radio reporting some engine trouble – to provide a fire alarm test for the ground team.
The next entry will come from western Greenland.

Drop-off at Daneborg Base
This is the runway at Daneborg, on the coast, around 25 km from Zackenberg.
There’s still a little ice on the sea here.(But all the scientific research at Z. confirms the trend of a decrease in the perennial sea-ice).
There is an old trapper station here, used nowadays with the other buildings here by the Danish military SIRIUS patrol, the one that’s famous for its dogsled activities. That goes out to patrol the coast and surrounding areas in the winter.
Denmark is keen to establish its sovereignty here on the remote north-east coast. The national park is the biggest park in the world, and there’s not much in the way of human activity up here. The territory of East Greenland was disputed by Norway early in the 20th century. These days, there’s a lot of talk of increasing military activities up here because of the growing interest in the natural resources of the Arctic, especially the supplies of oil thought to lie hidden under the ice at the moment. The parties in the Danish parliament recently agreed to create a special Arctic Task Force, combining those elements of their military units (mainly for Greenland and the Faroe Islands) specialized in Arctic activities. A Greenland home rule adviser told me he does not see this as increased militarization of the Arctic, as some fear, but just as an organisational shift, which will not include more resources. It certainly means a change in focus.There are likely to be more aircraft coming in here, at any rate.
Denmark has put forward claims to extend the continental shelf by territory around Greenland. Other Arctic states have put in their own claims. The UN commission on the Law of the Sea has to decide who owns what territory and could therefore lay claim to any oil, gas or mineral reserves found there.
Fuel for the base and Zackenberg is shipped into Daneborg, then flown on in smaller quantities.
Time to take off, and for the next stretch I have the famous POF twin otter all to myself.
This is going to be spectacular, as we are moving in from the coast a little over the icy mountains. Taking pictures in this historic plane can be challenging:
But I have a couple of windows to choose from – as long as I can reach them without loosening the belt.
I love the changing landscape and all the features you can see in the snow, flying this low:
I have many more of these ice-blog views, but will close for now with this one.
Nicely framed, huh? Courtesy of Twin Otter Pof.
Next stop, Krume Langso, the “long, curved lake”.

Time to Move On
Dryas, one of this region’s attractive flowers and also a source of food for Tomas’ caterpillars. I found a supply in the fridge, they’re starting to get scarce as the season progresses fast in this strong sunshine, and he puts them in glass phials with the creatures he is rearing as part of his experiments.
I found these growing down by the water, I’m not sure how to spell the name, so I’m not publishing without verifying, let’s make do with a look.
All too fast it’s my last day at Zackenberg Station. I’m the only one leaving this week, four new people are coming in. I’ve been put on standby all day, as the flight times can change at short notice. The Twin Otter coming in will be a famous one, the POF, apparently even the cover photo on one of THE books about these planes. Our logistics chief Philip is very excited about it. Its history goes right back to the Vietnam war, and it has been in many a scrape. I’ll ask the captain a bit about it later. I assume it has had a few spare parts since then.
Conditions seem idyllic, although the forecast says it’s likely to rain a little. No signs of any deterioration so far, as I sit on the bench outside the kitchen hut and catch up on my reading.
Lars and Philip keep reminding me things can change quickly up here. The plane has now radio’d it will be in at 15.26 (not a minute earlier or later!). I have everything ready. Then, at 15.10, although the sun is still shining, a wind comes up all of a sudden that is blowing things over, even chairs, and I have to beat a hasty retreat. People start running to secure anything that can blow away.
I think the little plane will never be able to land in this. Clearly I have no idea of the power of the “POF” and her Captain Jonas and his co-pilot. Although they asked me later when the storm had blown up at Zackenberg, because it had been fine until then, they come in without a problem.
The jackets are on, hoods up.
Scientific chief Lars battles the wind and makes his way to the runway.
Everyone who’s not out in the field heads towards the plane for the ritual farewell and welcoming of the new people.
The plane has landed, buffeted by the wind.
The Ice Blogger has to be photographed about to leave the station on the famous POF. I could feel it shaking in the wind as I leaned against it.
Time to say a very rushed goodbye in the excitement and off we went, two pilots, me and 3 men to be dropped off at Daneborg, the coastal military base, to be transported on further north to repair a remote hut. Daneborg will be the next stop.
