Greenland’s massive ice sheet is melting faster than expected, contributing to rising sea levels.

Catching  up on the last few weeks of icy news after a spring holiday, my eye was caught by an item by Tim Radford from the Climate News Network, dated April 13th. I quote: “Greenland is losing ice from part of its territory at an accelerating rate, suggesting that the edges of the entire ice cap may be unstable”. This caught my attention not just because anything relating to Greenland tends to do that, but because the development could have major significance for the future world climate and sea level- and because it doesn’t seem to have made its way into the mainstream media at a time when sensitivity to the issue should have been high after the IPCC report.

The Greenland ice sheet is the largest terrestrial ice mass in the northern hemisphere. Radford draws attention to a study in Nature Climate Change by Shfaqat Khan from the Technical University of Denmark and colleagues, which indicates that the ice sheet could be melting faster than previously thought. This would mean Greenland’s contribution to sea level rise has been under-estimated (once again!), and oceanographers may need to think again about their projections.

The scientists used more than 30 years of surface elevation measurements of the entire ice sheet to discover that overall loss is accelerating. Previous studies had identified melting of glaciers in the island’s south-east and north-west, but the assumption had been that the ice sheet to the north-east was stable, Radford writes:

“It was stable, at least until about 2003. Then higher air temperatures set up the process of so-called dynamic thinning. Ice sheets melt every Arctic summer, under the impact of extended sunshine, but the slush on the glaciers tends to freeze again with the return of the cold and the dark, and since under historic conditions glaciers move at the proverbial glacial pace, the loss of ice is normally very slow.”

But with global warming, Greenland’s southerly glaciers have been in retreat and one of them, Jakobshavn Isbrae or Sermeq Kujalleq, is now flowing four times faster than it did in 1997. I first reported on this during a trip to Greenland in 2010, and have presented various new studies on it here on the Ice Blog since.
The new research by the Danish-led team considers changes linked to the 600 kilometre-long Zachariae ice stream in the north-east, using satellite measurements. It has retreated by some 20 kilometres in the last DECADE, whereas Sermeq Kujalleq has retreated about 35 kms in 150 years. The Zachariae stream drains around one-sixth of the Greenland ice sheet, and because warmer summers have meant significantly less sea ice in recent years, icebergs have more easily broken off and floated away, which means that the ice stream can move faster. “North-east Greenland is very cold. It used to be considered the last stable part of the Greenland ice sheet,” said one of the team, Michael Bevis of Ohio State University in the US, in an interview with the Climate News Network.

“This study shows that ice loss in the north-east is now accelerating. So now it seems that all of the margins of the Greenland ice sheet are unstable.”

The scientists used a GPS network to calculate the loss of ice. Glacial ice presses down on the bedrock below it: when the ice melts, the bedrock rises in response to the drop in pressure, and sophisticated satellite measurements help scientists put a figure on the loss of ice. They calculate that between April 2003 and April 2012, the region was losing ice at the rate of 10 billion tons a year.

“This implies that changes at the margin can affect the mass balance deep in the centre of the ice sheet,” said Dr Khan. Sea levels are creeping up at the rate of 3.2 mm a year. Until now, Greenland had been thought to contribute about half a mm. The real figure may be significantly higher, according to the report.

This is a very worrying development, but it seems to me it did not get a lot of public attention. This brings me back to the question of the discrepancy between what we know about the impacts of climate change and the widespread lack of political and consumer action. (See my article Denial or Disconnect: Why don’t we act on climate change?)

Are people sticking their heads in the sand (or melting snow)? Have we just been assured so many times that the Greenland ice sheet will never melt that we don’t sit up and take notice? Is it too far away in time and space to bother us? Are too many people giving up and resigning themselves to the fact that climate change is inevitable? Is it just so much easier to hold on to the status quo instead of having to make changes to our 21st century lifestyles?

No oil needed for this one! (I. Quaile 2014)

Back in January, China’s state-owned oil company CNOOC obtained an Arctic exploration licence for the remote Dreki area, 125 miles off the north coast of Iceland. Iceland has very close relations with Beijing. When I interviewed the Foreign Minister Gunnar Bragi Sveinsson at an event in Tromso earlier this year, he told me:

“We have a very good cooperation with China. We hope our Free Trade Agreement will be fully implemented in the summer. China is a very big player in the world economy. They are showing interest in the Arctic, interest in western Europe, and we treat them like anybody else in the world. As long as they play by Icelandic rules, Icelandic law, we don’t worry. I see opportunities in working with China, no threats”.

I was interested to come across a short item by the news agency AFP about a group that sees Arctic development a little differently; the Iceland Nature Conservation Association. Their opposition has nothing to do with the fact that China is investing in the region, but with the basic fossil fuels-climate paradox. The agency quotes the chairman, Arni Finnsson:

“Iceland should not bet on oil at a time when it is doubtful that humanity can reach its (greenhouse gas) goals.”

Apart from the climate implications, Finnsson says oil production in the area envisaged by CNOOC along with Icelandic firm Eykon Energy and Norway’s state-owned Petoro  is unlikely to be cost-efficient. The cost factor is one analysts say will play the key role in determining whether offshore oil exploration in the Arctic will be viable, as discussed on various occasions here on the Ice Blog.

Iceland is still recovering from the financial crisis of 2008-2009 and hopes to follow in neighbouring Norway’s footsteps and build a lucrative oil industry.  “That is the hope,” Thorarinn Sveinn Arnarson, who heads the hydrocarbon licensing department at Iceland’s national energy authority, told AFP.  “If something is found that is economically viable there would be tax benefits and of course all the other things, job creation and technical capacity like we’ve seen in Norway and in the Faroe Islands.”

But experts warn that this vision could be some way off if it ever materialises. Dag Claes, a leading oil and gas expert at the University of Oslo, stresses the remoteness of the area. He also draws attention to the problems of developing a suitable infrastructure for an oil industry in this part of the world, a problem I wrote about here on the Blog recently.

Since I attended a workshop on “Creating a Climate for Change” in Tromso in January, I have been thinking a lot about the psychological reasons why things are not moving forward on climate change. Although scientific knowledge is growing all the time,  public perception of the need for action has not kept pace. Even in regions of the Arctic where climate change is very visible, a lot of people seem to be unwilling to take it on board. Of course there are people who will benefit to some extent. But the danger of a warming world for future generations and the environment is hard to avoid. Yet there is what you could all collective inaction.  Is it all in the mind? I touched on this briefly in a post from Tromso, but feel it is important enough to come back to in some more detail here.

In connection with climate change, the word “denial” is highly emotionally charged. Her book entitled “Living in Denial: Climate Change, Emotions, and Everyday Life” brought American sociologist Kari Norgaard storms of hate mail from right-wing climate skeptics. Yet the academic from the University of Oregon is not concerned with this minority group.

“I think it is a very disingenuous debate that has been manufactured by political interests who stand to lose as the economy shifts away from fossil fuels. What they’re doing is trying to make it sound like there is a debate – but actually there is no debate”, Kari told me in an interview. What she wants to understand is why the vast majority of people who do not dispute the existence of human-induced climate change still fail to translate that knowledge into action in their own lives.

“How is it possible that we have so much knowledge about the urgency of climate change, yet when you look around, it seems that either nobody knows or nobody cares?”. Norgaard sees an “incredible disconnect between the moral, social and environmental crisis of climate change and the lack of a widespread sense of a need for urgent action.” Humans, says Norgaard, are “not getting it” and “carrying on regardless”.

Refusing to accept the obvious?

The American researcher spent ten months studying a community in northern Norway, a country where media literacy, political participation and climate awareness are high. The winter she spent there was unusually warm and the snow came two months later than usual, causing problems for the community’s two main revenue sources farming and tourism. Yet Norgaard observed that the phenomenon of climate change was “invisible in social or political life”. Although stories in the media linked the warm winter explicitly to global warming, residents did not react by contacting politicians or cutting down on fossil fuels. Norgaard attributes this lack of response to what she calls “socially organized denial”: although people are informed about the findings of climate science, this knowledge remains disconnected from political, social, and private life. She sees this as symbolic of how citizens of wealthier, industrialized countries are responding to global warming. In her home county the USA, regions are already experiencing climate impacts with economic consequences. Yet people do not want to accept that it could have something to do with their lifestyle and require unpleasant action.

Lifestyle and melting ice? (Pic I.Quaile, Alaska 2008)

“People have a real fear about what it means for the world and their future. Then a sense of guilt comes up because they realize that our high quality of life through our use of fossil fuels is directly linked to this problem. Then there is a sense of helplessness, because it feels so large and we see the lack of political response.”

People prefer, it seems, to live as though they did not have the worrying evidence of climate change. Norgaard compares this behaviour to people’s ignoring the holocaust or the dropping of the atomic bomb during World War II: She thinks we are trying to protect ourselves by avoiding unpleasant facts and the need to do something about them.

The greatest communication failure of all time?

Per Espen Stoknes is a psychologist at the Center for Climate Strategy of the Norwegian Business Institute NBI. He says the communication of climate science has failed to take account of psychological defence mechanisms of the sort Norgaard describes. “For a long time it was hoped that just the facts would be sufficient. But there are psychological barriers which stop people taking to heart what climate science is telling us, and these have been underestimated”, he told me in an interview.

Stoknes says people perceive climate change as something distant, in time and place. An IPCC (intergovernmental Panel on Climate Change) forecast for 2100 seems a long way away. Melting sea ice or sea level rise in places like Bangladesh or the Maldives seem geographically very remote.

Paradoxically, the better the facts on climate change become, the less people seem to care. Stoknes quotes surveys going back to 1989 in Norway which show a decrease in people’s concern about the greenhouse effect and climate change.”Only four in ten now see it as a problem”.

Another interesting statistic Stoknes quotes shows the public has the impression only 55 percent of climate scientists agree on global warming. In reality, the figure is 97%.Getting the message about climate change across is the “greatest communication failure of all time”, says Stoknes. He says scientists need to lecture people less and engage more in dialogue and discussion. Media coverage also plays a role: “We know about 85 percent of all the media reports about climate have been framed as doom and disaster. We know this gives people an aversion and leads to avoidance behaviour. We stop wanting to hear about the issue”.

This would appear to fit with a downward slide in climate coverage around the globe, says Elisabeth Eide from the University of Bergen, author of various works on climate change in the media. She refers to “climate fatigue” in society at large and in journalists in particular.

How to motivate people to combat climate change?

 If these researchers are correct and the lack of climate action is mainly psychologically motivated, the problem requires psychological solutions. Stoknes says we have to cross the “doom and disaster barrier” and point the way forward. Norgaard too argues for more positive examples and indications of what we could do to change things.”.

Psychologist Stoknes stresses the power of social norms to change behaviour: He suggests campaigns that make people compete with their peers – neighbours, other towns, friends, relatives, at being climate-conscious. He reports the success of an app where people can record and compare how much energy they have used. Another possibility is to make “greener” options the default in all aspects of daily life. “If the normal way a printer works is to use both sides of the paper, for instance, people will do that. Not if they have to change a setting” says Stoknes. A mind-shift away from portraying climate change as a paralysing threat towards stressing practical behaviour that would change the situation could avoid triggering what the experts call “the emotional need for denial”. Any thoughts on that?

Melting ice, off  Greenland (I.Quaile)

Trawling the media for climate-related stories over the weekend, I began to see some signs that the message might be getting across after all. I had just put the finishing touches to my story on “Why we don’t want to hear about climate change“, based on interviews with sociologist Kari Marie Norgaard from the University of Oregon and psychologist Per Stoknes from the Norwegian Business school, when I heard US Secretary of State John Kerry’s announcement that the USA and China would be cooperating and exchanging data in the run-up to the 2015 Paris climate talks, where a new climate deal is supposed to be agreed. I found myself feeling just a little bit more optimistic. If these two key players really put climate protection into action, maybe we will be able to get somewhere. A report on a study by the Chinese government on the disastrous air pollution in Beijing is not happy reading, but gives grounds to assume the Chinese government has to be serious about taking emissions in hand.

Arctic ambassador – a sign of the times?

Another announcement by the US Sec of State leaves me with mixed feelings. There is going to be a US ambassador for the Arctic. On the one hand, it is always good to see the Arctic getting attention. On the other hand, the motivation does not make me jump for joy. An item from the news agency AFP writes of “a region increasingly coveted by several countries for its oil and other raw materials”. Indeed. That is the worrying bit. In case you missed it, (the Arctic announcement did not get huge coverage), Kerry said in his statement:

“The Arctic region is the last global frontier and a region with enormous and growing geostrategic, economic, climate, environment and national security implications for the United States and the world…President Obama and I are committed to elevating our attention and effort to keep up with the opportunities and consequences presented by the Arctic’s rapid transformation – a very rare convergence of almost every national priority in the most rapidly-changing region on the face of the Earth”. It is good to see climate and environment get a mention at least.

A “Stern” warning

The Guardian had a guest article by Nicholas Stern, the author of that famous Stern Report on the economics of climate change back in 2006 (yes, it really is that long ago).The background to this, of course, is the wild weather in the UK. Now I do not wish that kind of weather on anyone, but in terms of drawing attention to climate change it has certainly been very important. Stern writes “The record rainfall and storm surges that have brought flooding across the UK are a clear sign that we are already experiencing the impacts of climate change”. He makes a clear case for linking the two. He also brings in the other extreme weather around the globe, including Australia, Argentina and Brazil and the devastating typhoon Haiyan in the Philippines last year. Stern has clear advice for the politicians:

“This is a pattern of global change that it would be very unwise to ignore.” Stern says the risks are even bigger than when he wrote the 2006 report. “Since then, annual greenhaouse gas emissions have increased steeply and some of the impacts, such as the decline of Arctic sea ice, have started to happen much more quickly.”

I hope a lot of decision-makers and influential business people have read or will still read Stern’s article. He calls for rapid action and investment. He has a clear message for the European Union, currently not the most popular international organisation with the British government. “The UK whould work with the rest of the EU to create a unified and much better functioning energy market and power grid structure. ‘this would also increase energy security, lower costs and reduce emissions. What better was is there to bring Europe together?” Other measures recommended would be to implement a “strong price on greenhouse gas pollution across the economy”. This, remember, is a renowned economist, not an environmental campaigner. He also warns against the temptation to cut overseas aid to fund adaptation to climate change. “It would be deeply immoral to penalise the 1.2 billion people around the world who libve in extreme poverty…In fact, the UK should be increasing aid to poor countries to help them develop economically in a climate that is becoming more hostile largely because of past emissions by rich countries”- Yes. Yes. Yes.

Don’t let the weather distract from your climate awareness!

The other piece of writing which inspired me over the weekend was in the ImaGeo blog by Tom Yulsman: “Move over polar vortex“. He looks at the new analysis produced by the UK’s Met Office:

“If a new scientific analysis is correct, the repeated bouts of extreme weather on either side of the Atlantic are indeed unusual – and both are manifestations of a chain of climatic teleconnections that reach half way around the globe and all the way to the tropics”.

There is a lot of talk in this piece of whether the polar vortex is weak (as discussed in my article More Arctic Weather in a Warming World?) Or actually “particularly intense”. I would recommend you read Tom’s blog for yourselves for the details and his views. But the insight I would leave you with here as “food for thought” is where he quotes a paper in the journal Science.

“They conclude that the recent discourse focusing on the possible connections between winter weather and climate change distracts from the bigger issue: that is, regardless of extreme winter weather, climate change is undoubtedly real, and that harsh winters are not what we really need to be concerned about going forward as the climate continues to change”.

Begich Boggs, Alaska 2008. No glacier in sight! (I.Quaile)

People love to talk about the weather. But if we use every instance of unusual weather to question the overall trend of global warming, with all the complex effects that has on our climate, winds, oceans etc, we run the risk of losing a necessary sense of urgency when it comes to reducing emissions. I am reminded, as I often am, of a young climate ambassador from the Netherlands during a fact-finding trip to Alaska in 2008. As we stood at the Visitor’s Centre for a glacier which is now no longer visible from that spot because it has retreated so far, he said that just brought home to him how “everything is connected”. Our everyday lifestyle in the industrialised world is melting the Arctic ice – and that, in turn, is contributing to the changing climate patterns which can radically alter the planet.
