Climate change is causing rapid, deeper and more extensive acidification in the Arctic Ocean
A new study reported in Nature Climate Change this week says ocean acidification is spreading rapidly in the western Arctic Ocean in both area and depth. That means a much wider, deeper area than before is becoming so acidic that many marine organisms of key importance to the food chain will no longer be able to survive there.
The study by an international team including scientists from the USA, China and Sweden, is based on data collected between the 1990s and 2010. Presumably, things have got worse rather than better since then. Unfortunately, it takes a long time for scientific research to be evaluated, reviewed and published, so current developments can easily overtake assessments which are already alarming enough in themselves. So yes, I would say this should make us sit up and listen, and lend even more urgency to the need for reducing emissions and combating climate change.
Acid bath for shellfish
Ocean acidification is a process that happens when carbon dioxide out of the air dissolves in the sea, lowering the pH of the water. This reduces the concentration of aragonite in the water, a form of calcium carbonate which shellfish and other marine organisms use to build their shells or skeletons. If the water becomes too acidic, this cannot be formed to the same extent, leaving the animals without their protective shells.
The latest published research shows that acidification is not only affecting much wider areas of the Arctic Ocean, but also that it is happening down to a much greater depth than before.
Between the 1990s and 2010, acidified waters expanded northward around 300 nautical miles from the Chukchi slope off the coast of northwestern Alaska, to just below the North Pole, the scientists write. At the same time the depth of acidified waters has increased from approximately 325 feet to over 800 feet, or from 100 to 250 metres.
“The Arctic Ocean is the first ocean where we see such a rapid and large-scale increase in acidification, at least twice as fast as that observed in the Pacific or Atlantic oceans”, said Professor Wei-Jun Cai from the University of Delaware and Mary A.S. Lighthipe, Professor of Earth, Ocean and Environment at the same University. Cai is the US lead principal investigator on the project.
“The rapid spread of ocean acidification in the western Arctic has implications for marine life, particularly clams, mussels and tiny sea snails that may have difficulty building or maintaining their shells in increasingly acidified waters”, said Richard Feely, senior scientist with NOAA and a co-author.
Tiny sea snails called pteropods are part of the Arctic food web and important to the diet of salmon and herring. Their decline could affect the larger marine ecosystem.
Among the Arctic species potentially at risk from ocean acidification are subsistence fisheries of shrimp and varieties of salmon and crab.
The polar regions are suffering more than others, because cold water absorbs CO2 faster.
Less ice to hold back warm water
The acidification study published this week used water samples taken during cruises by the Chinese ice breaker XueLong (snow dragon) in the summer 2008 and 2010 from the upper ocean of the Arctic’s marginal seas, right up to the North Pole, as well as data from three other cruises going back to 1994. The data, along with model simulations, suggest that increased Pacific Winter Water, driven by circulation patterns and retreating sea ice in the summer season, is primarily responsible for the expansion of ocean acidification, according to Di Qi, the lead author of the paper.
This water from the Pacific comes through the Bering Strait and shelf of the Chukchi Sea into the Arctic basin. Melting sea ice is one factor which allows more of the Pacific water to flow into the Arctic Ocean. The Pacific Ocean water is already high in carbon dioxide and has higher acidity. As it moves north, its acidity increases further for various reasons.
The melting and retreating of Arctic sea ice in the summer months also lets Pacific water move further north than in the past.
The scientists have observed that Arctic ocean ice melt in summer used to occur only in shallow waters with depths of less than 650 feet or 200 meters. But now, it spreads further into the Arctic Ocean.
“It’s like a melting pond floating on the Arctic Ocean. It’s a thin water mass that exchanges carbon dioxide rapidly with the atmosphere above, causing carbon dioxide and acidity to increase in the meltwater on top of the seawater”, said Cai. “When the ice forms in winter, acidified waters below the ice become dense and sink down into the water column, spreading into deeper waters.”
Climate chaos – not just for polar bears
In 2010, I spent some time with scientists conducting the world’s first experiments in nature, off the coast of Svalbard, to establish exactly how increasing acidification affects the flora and fauna in the Arctic Ocean.
Mesocosms, or giant test-tubes, were lowered into the sea to capture a water column with living organisms inside it. Different amounts of CO2 were added to simulate the effects of different emissions scenarios in the coming decades.
Similar experiments are still being conducted in different ocean areas. Results so far have been scary to say the least.
Mussels, snails, sea urchins, starfish, coral, fish, “some of these species will simply not be able to compete with others in the ocean of the future”, Ulf Riebesell from the Helmholtz Institute for Ocean Research in Kiel, GEOMAR, told me in an interview back in 2013, when he was a lead author of a report by the International Programme on the State of the Oceans (IPSO). He was also one of the scientists in charge of that first Arctic acidification in situ experiment I witnessed back in 2010. He is currently coordinator of the German national project Biological Impacts of Ocean ACIDification (BIOACID).
Riebesell says the sea water in the Arctic could become corrosive within a few decades. “The shells and skeletons of some sea creatures would simply dissolve”, he told me.
Those feedback loops
February 27th was Polar Bear Day. Attention focused on how the decline of sea ice is having devastating impacts on those iconic creatures, who have become a key symbol of the effect of our human-induced climate change on the Arctic. Sea snails may not be quite as charismatic, but the related threat to all these tiny organisms in the water is no less worthy of our attention. Journalist Chelsea Harvey of The Washington Post writes:
“The Arctic is suffering so many consequences related to climate change, it’s hard to know where to begin anymore (…) The study highlights the interconnected nature of climate consequences in the Arctic – the way that greenhouse gas emissions, rising temperatures, ice melt and ocean acidification are all linked and help to reinforce one another. And it points to yet another example of a climate effect that’s not just a concern for the future, but is already an issue – and a growing one – today.”
Indeed, Chelsea. Climate change is already changing our lives and our planet. And, of course, what happens in the Arctic doesn’t stay in the Arctic. The scientists studying ocean acidification and its impacts are also concerned about a feedback effect that will further exacerbate global warming.
When the IPSO report on the state of the oceans was published, I interviewed the organisation’s scientific director Alex Rogers, a professor of conservation biology at the University of Oxford. He told me the oceans were already taking up about a third of the carbon dioxide we are producing. The report said sea water was already 26 percent more acidic than it was before the onset of the Industrial Revolution – and it could be 170 percent more acidic by 2100. In the long run, the ocean will become the biggest sink for human-produced CO2, but it will absorb it at a slower rate.
“Its buffer capacity will decrease, the more acidic the ocean becomes”, Kiel-based scientist Ulf Riebesell told me.
The IPSO report also drew a very unsettling comparison between conditions today and climate change events in the past that have resulted in mass extinctions:
“On a lot of these major extinction events we see the fingerprints of high temperatures and acidification, similar effects to the ones that we are experiencing today”.
Now there is a frightening possibility.
It is not too late to do something about this, although the experts stress the CO2 will remain in the oceans for thousands of years. The scientists tell us the key step would be to reduce greenhouse gas emissions, but also to reduce pollution and other pressures on the ocean ecosystem, which reduce its resilience. High time for the Clean Seas initiative, to reduce ocean pollution from marine litter, especially from plastic, launched this week by the United Nations Environment Programme.

Will new climate scientist on board influence Exxon?
Last year I had an interesting guest in the studio here at Deutsche Welle. We talked for a good half hour about climate change and the ocean and the need for the Paris Agreement to be put into action, and whether we can still save the Arctic ice as we have known it in our lifetimes.
Excerpts from the interview were broadcast on Living Planet and published online.
Susan Avery is an atmospheric scientist. She was President and Director of the renowned Woods Hole Oceanographic Institute from 2008 to 2015, and became a member of the scientific advisory board to UN Secretary General Ban Ki Moon in 2013. She was in Bonn for a lecture organized by Björn Müller-Bohlen from the department of strategic partnerships at the Forum of International Academic Sciences in Bonn, to explain to people here how climate change is affecting the ocean.
I was surprised to say the least when I saw that from the beginning of February Dr. Susan K. Avery had been elected to the board of directors of ExxonMobil.
So the former Exxon chief Rex Tillerson has taken the key post of Secretary of State in the Trump administration, climate skeptic Scott Pruitt takes over the EPA, the world worries about the future of the climate and the environment – and a leading climate scientist has joined the “largest publicly traded international oil and gas company and one of the largest refiners and marketers of petroleum products”, as ExxonMobil describes itself. It is also at the centre of a huge controversy over claims that it denied climate change, covering up facts and funding climate skeptic bodies. Interesting times indeed. (The Dawn of the Trumpocene?) What are we to make of it all?
I emailed Dr. Avery to try to arrange another interview to discuss her motivation and expectations. She did respond swiftly, telling me she was “honored to be elected to the Board and look forward to serving in that capacity.” But interview requests are being handled by Exxon.
Reactions to her appointment have been mixed, ranging from those who see this as a mere greenwashing type of move by Exxon, and those who think this represents a gradual shift in thinking in the corporation (pragmatic shift to renewable energies given the problems ahead for fossil fuel companies?) and the optimists who think this could possibly even be a chance for a climate expert to influence the policies of the fossil fuel giant and a sign that the times are ‘a changin’.
From the “horse’s”mouth
I decided to have another look and listen to the interview I recorded with Dr. Avery last year, to remind myself and those who will be watching her actions with interest, of what she stands for when it comes to protecting the climate, the ocean and the Arctic.
She is certainly in no doubt about the human factor in climate change. When I mentioned that we humans had been “interfering” with the climate, she laughed good-naturedly at my under-statement, and went on to elaborate on how we are increasing the temperature of the atmosphere by infusing carbon into it. She clearly named fossil fuels as a cause. So what, I wonder, will she be telling the board of ExxonMobil?
Our subject was the effect of greenhouse gas emissions on the oceans in particular. She stressed that while 25 percent of the carbon dioxide we release goes into the atmosphere, a stunning 93 percent of the extra warming created is in the ocean. I went on to ask her about the impacts:
“The carbon dioxide we’ve put into the atmosphere already and the heating associated with that means that we’re already pre-destined for a certain amount of global temperature increase. Many people say we have already pre-destined at least one and a half degrees, some will say almost two degrees. That’s why it’s really important to address the warming questions. And I was really pleased to see the Paris Agreement finally signed off on.”
Fossil fuel threat to the ocean
With the future of US participation in implementing the Paris Agreement very much up in the air under the Trump administration, one wonders how Avery is going to push the decarbonisation of the economy necessary to keep anywhere near the two degree limit, on the board of one of the world’s biggest oil and petroleum concerns.
She also stressed in her talk with me the huge threat to the food chain posed by ocean acidification, as carbon dioxide emissions change the PH of the ocean.
“Our coral reef systems and a lot of our ecosystems in the ocean are having a battle with warming, and those ecosystems that involve shell production and reproduction, as in our reef systems, are also battling acidification issues. This is really critical, because it attacks a lot of the base of the food chain for a lot of these eco-systems. “
Another of the threats to the ocean and the creatures in it is pollution, and Avery told me her time as head of Woodshole was a time of “many crises in the ocean” – including the Deep Water Horizon oil spill:
“That was a real challenge for us in terms of looking at the technologies we have in a different way, solving a different type of problem, and from these crisis moments we learned a lot about our science and our technology, and how to improve it and go forward.”
Well, here’s hoping that knowledge and Dr. Avery’s expertise here will help the company where she is now on the board.
Kudos for the journos
Another point that came out of our interview was Avery’s firm belief in the key role the media have to play in explaining what is happening to our climate and environment to “ordinary people”.
“It is things like Living Planet and others that really begin to educate people and involve people in understanding their environment and their planet,” she said in the DW studio.
As host and producer of Living Planet together with my colleague Charlotta Lomas, it was good to have that acknowledgement from a leading scientist and adviser to the UN. Avery also mentioned progress in recent decades in raising public awareness of environmental issues, such as pollution or acid rain, thanks not least to media coverage.
Unfortunately that job is not made any easier – especially in the United States – with an administration that tries to gag journalists and, it seems, any organization that does not spread the information the government think should be spread.
Motives and methods
So what motivates someone like Susan Avery to take on a controversial position like board membership on a company whose main business results in harmful changes to the planet which she has been working for years to publicise? Perhaps another snippet from the interview can shed some light, when I asked my guest Avery how she had come to be a member of the board of advisors to Ban Ki Moon (not that I would compare that to joining ExxonMobil).
“I was intrigued by the opportunity to play on a stage level that was very high politically, and making sure that science was interfaced in a number of dimensions, into the policy and decision-making process at that level. The committee itself is a wonderful board in terms of the different disciplines represented, different countries represented, different perspectives we all have on the science and the environment, and on human health issues, that the UN needs to be cognizant of.”
Clearly, this is a woman who likes to be in influential positions – and to bring different camps and expertise together:
“We talked a lot about science, the policy-society interface, the role and engagement of stakeholders, those are governments at all levels, the business community, and conservation.
What about the Arctic?
Of course one of the Iceblogger’s most urgent concerns is what climate change is doing to the polar regions. With record temperatures in the Arctic and record low sea ice cover, I asked Avery to sum up the impacts for our Living Planet listeners. She expressed her concern that “we are beginning to see a very rapid increase in ice loss in the Arctic”. She cited the melting of the big land ice glaciers as a major contributor to sea level rise. She talked of how not only atmospheric temperature but warming ocean waters are degrounding glaciers and melting ice from below:
“That is a major concern for sea level rise, but also because when the land-based ice comes into the ocean, you get a freshening of certain parts of the ocean, so particularly the sub-polar north Atlantic, so you have a potential for interfacing with our normal thermohaline circulation systems and (this) could dramatically change that. Changes in salinity are beginning to be noticed. And changes in salinity are a signal that the water cycle is becoming more vigorous. So all of this is coupled together. What’s in the Arctic is not staying in the Arctic. What’s in the Antarctic is not staying in the Antarctic. I would say the polar regions are regions where we don’t have a lot of time before we see major, massive changes”.
So let us hope Dr. Avery will be able to convince her fellow board-members and the decision makers at ExxonMobil about that – and about what has to happen. Fossil fuel emissions in general have got to go down. And the fragile Arctic in particular is in need of protection. Clearly, she has her work cut out for her.
Is there still time?
Reporting Avery’s appointment to the ExxonMobil board, the news agency AFP quotes her as saying:
“Clearly climate science is telling us (to) get off fossil fuels as much as possible.”
I asked her whether she believed, given that we have already put so much extra CO2 into the atmosphere and the ocean, that there was any way we would be able to reverse what is happening in the Arctic. Her reply – unsurprisingly – was not too reassuring:
“I don’t have an answer, to be honest. I think we’re still learning a lot about the Arctic and its interface with lower latitudes, how that water basically changes circulation systems, and on what scale. (…)We know so little, about the Arctic, the life forms underneath the ice (…) And I think it’s really important, because the Arctic will be a major economic zone. We’ve already seen the North-West Passage through the Arctic waters, we’re going to see migration of certain fisheries around the world, and we don’t even know completely what kind of biological life we have below that ice. We have the ability to get underneath the ice now. I call these the frontiers, of the ocean, and that includes looking under ice. It’s a really exciting time.”
If that excitement can be put into protecting the fragile polar ecosystems rather than taking advantage of our emissions misdeeds to date to use easier access for commercial exploitation, I am all for it.
ExxonMobil remains a primary target of environmentalists. It has been the subject of investigative reports by environmental news nonprofit Inside Climate News and others, saying it “manufactured doubt” about climate science even while contradicted by research by its own climate scientists. The company says the reports are biased, but faces government investigations over the controversy. In January, a Massachusetts court ruled the oil giant must turn over 40 years of documents on climate change, in a win for Massachusetts Attorney General Maura Healey, who has described the probe as a fraud investigation. ExxonMobil has countersued against Healey, arguing she lacks jurisdiction in the matter.
As I indicated above, there are environmentalists who were not impressed by the appointment of a climate scientist to the fossil fuel giant’s board. AFP quotes Shanna Cleveland of Ceres, a nonprofit group that works on shareholder actions to pressure companies to address climate change. She called the move a “really good first step, but not much more than that”, and fears Susan Avery could be a “lone vote in the wilderness” on climate change given ExxonMobil’s record on the issue.
The climate advocacy group 350.org dismissed the appointment as “little more than a PR stunt.”
Scientists to the fore
But at a time when some critics say the Trump administration is threatening environmental democracy in the USA, I would prefer to see Dr. Avery’s new position as a move in the right direction, if a tiny one.
With scientists gearing up to march on Washington in the not-too-distant future, we can do with experts who acknowledge, understand and call for action on climate change on every level, in every corner.
Susan Avery described her time on the UN scientific advisory board in her interview with me here in Bonn as as “a fun exercise.” In the current climate, I cannot imagine the same will apply to being the climate advocate on the board of a controversial fossil fuels giant like ExxonMobil.

Some Arctic good news – not #fakenews!
With the environment and climate under constant fire from the actions of President Trump, it is great to end the week with a little piece of good news.
This is the time of the year when Arctic buffs gather in Tromso in Norway for the annual Arctic Frontiers conference. I couldn’t make it myself this time, but have been following some of the action online, including the side-events which are often amongst the most valuable at international conferences.
Push for clean shipping
One thing that made me smile was the announcement that the famous cruise ship operator Hurtigruten had signed the Arctic Commitment, calling for a ban on the use of marine heavy fuel oil (HFO) in the Arctic.
The Clean Arctic Alliance – a coalition of environmental NGOs – is calling on the international community to sign up to the Arctic Commitment with the aim of protecting Arctic communities and ecosystems from the risks posed by the use of HFO.
The CEO of Hurtigruten, Daniel Skjeldam, signed the Arctic Commitment in Tromso.
“The use of heavy fuel oil has already been banned in the Antarctic, now it’s time to ban it in the Artic as well”, Skjeldam said. His company has chosen not to use heavy fuel oil in any of its ships.
Oil spill risk in icy waters
He urged the shipping industry to be frontrunners in “promoting regulations that will secure sustainable Arctic growth”.
“An accident involving a mega ship and spill of heavy fuel oil in the Arctic should represent an environmental disaster”, Skeldam said. There has been no shortage of experts testifiying to that.
“If heavy fuel oil is spilled in cold Arctic waters, it will have larger consequences than anywhere else. The Arctic deserves sustainable growth and innovation, and the industry needs to move first”, the shipping executive confirms.
Don’t wait for a ban
Indeed. The shipping industry could make a huge difference here by taking action without waiting for legislation or restriction. With climate change speeding ahead and the Arctic struggling to cope with the rapid changes occurring as temperatures reach record highs, while powerful politicians like Presidents Trump and Putin seem more interested in exploiting the Arctic than protecting it, companies and consumers have to take on more responsibility.
In December 2016, Canada and the US announced a joint “phase down” of HFO from their respective Arctic regions. Here’s hoping things will move forward on this in spite of the current political climate.
The Clean Arctic Alliance believes a ban on HFO in the Arctic can be achieved by 2020 if governments and business demand action by the International Maritime Organization to ban the use of HFO. In the meantime, the group is encouraging the shipping industry to switch to higher quality, alternative fuels.
Christoph Wolff, Managing Director of the European Climate Foundation, a member of the Clean Arctic Alliance, says the debate on HFO is over. “Banning the use of heavy fuel oil to power Arctic shipping will not only minimize the risk of spills, but will also help reduce climate-warming emissions in the region”, he says.
When I first reported from Arctic Frontiers back in 2007, there was already a heated debate going on between those who want to develop and commercially exploit the Arctic’s resources, against the background of a warming climate, and those who want to restrict access and activity in the interests of the fragile environment and the communities who live there. I remember a discussion on the paradox of climate warming making it possible to extract more oil from the Arctic which would, in turn, cause more emissions and further melt. Shipping, too, both passenger and freight, becomes easier as the Arctic ice melts, but, in turn, causes high emissions as well as other pollution in the sensitive region.
So let’s go into the weekend with a round of applause for the tireless campaigners for a clean Arctic. It is hard for an environment journalist to be optimistic in these difficult times. But every little helps. And winning over the cruise ship industry which so many people associate with holiday expeditions into remote areas with intact nature and spectacular wildlife would be a great way to get a wider public “on board” for the voyage to protecting the icy regions of our warming planet.

Arctic climate (anti-)Trump card in Davos
With the Trump inauguration looming large, we have every reason to be more concerned than ever about the prospects for the climate. And given that the Arctic is warming twice as fast as the rest of the world, the high north could be said to be in double trouble.
All the more reason to look beyond the political stage in the narrowest terms to push the need for climate action. Take, for instance, the “Arctic Basecamp” which has been set up in Davos in Switzerland, where that illustrious gathering the World Economic Forum (WEF) is underway. “Responsive and responsible leadership” is the theme, with 3,000 participants attending, more than ever before. And the biggest delegation is from the USA, with 836 participants.
— ArcticBasecamp Davos (@ArcticDavos) January 17, 2017
Given the president elect’s views on climate change, the decision by some influential scientists to use the mega economic gathering of the great and mighty is a smart move. It seems the time has come to acknowledge that we cannot rely on governments alone to halt climate change and preserve the Arctic ice. Maybe we just have to admit that business has a huge impact, huge potential, and should bear a lot of the responsibility for climate protection? And of course, the chance to get an urgent climate message across to a group of highly influential people from business and politics is just too good to miss.
Time for some responsive and responsible leadership for the Arctic?
A group of leading scientists are holding an Arctic Science Summit in Davos on January 18th, and plan to call on global leaders for immediate action on the Arctic. The summit is a collaboration between Lancaster University, the British Antarctic Survey (BAS) and the Swiss Federal Institute for Forest Snow and Landscape Research (WSL).
Against the background of unprecedented temperatures almost 20 °C (36 Fahrenheit) warmer than normal in some parts of the Arctic this winter, the summit is designed as a call to action to global leaders to apply the theme of “Responsive and Responsible Leadership”, in tackling the global risks posed by Arctic change. Al Gore, Chair of the Climate Reality Project and Christiana Figueres, the former Executive Secretary of the United Nations Framework Convention on Climate Change, are amongst the high profile figures invited.
The summit is being hosted in Arctic Basecamp style tents in the grounds of the WSL, which is aptly positioned close to the official delegate hotel. A good publicity stunt. The tents are a catchy contrast to the luxury accommodation around them. The equipment is provided by the British Antarctic Survey, (BAS) another of the organisers. A reputed scientific organization and active in a region that captures the imagination of a wide audience as the coldest, remotest place on the planet. And which, still, is not immune to the effects of global warming.
Global platform for Arctic action
To Iceblog readers, the message from Jeremy Wilkinson, one of the organizers from BAS, comes as no surprise: “What happens in the Arctic doesn’t stay there. The Arctic is the canary in the coalmine for the world’s climate.” But many of the world’s most powerful decision-makers still haven’t got the message, he says. (Tut-tut, not all following the Iceblog??):
“It (the Arctic) is sending us a warning cry that has profound consequences and risks globally. Yet the Arctic remains invisible to the world’s most powerful decision-makers. We want to change that.”
“We know that science has important answers in assessing the global risks associated with the Arctic ice melt and we need to make this as visible as possible in Davos. Arctic change is at a critical juncture; hard choices need to be made. These must be evidence-based and not ideologically driven. Ultimately we want to see a new Global Platform for Arctic Action, and it starts here with this summit.”
Renowned climate expert Professor Konrad Steffen is Director of the Swiss Federal Institute for Forest, Snow and Landscape Research WSL. He, too, stresses the need for urgent action and the global relevance of the melting ice:
“The Polar Regions, as well as Alpine regions, will experience two to three times the mean level of global warming predicted for the future. We need to act swiftly to delay, or prevent, the loss of the ice masses in the mountains and the shrinking of the two polar ice sheets which will lead to unsustainable sea level rises.”
“Everybody who’s anybody…”
In a piece for the Arctic Journal entitled “Bringing the Arctic to the mountain”, journalist Kevin McGwin writes:
“Unofficially, Davos is the place to be if you consider yourself to be anyone in politics, business or the non-profit industry, and folks who attend have a saying of their own: the more programme events you turn up at, the less you get out of it. The real action takes place on the sidelines.”
Here’s hoping there is plenty of that at the Arctic Basecamp. McGwin goes on:
“Considering that 3,000-person guest list starts with António Guterres, the newly installed UN secretary-general, and encompasses multiple heads of state (including Xi Jinping) and captains of industry from over 1,000 companies, there is probably something to this.”
Indeed. If you want to reach a lot of very influential people with a message about risks associated with climate change, Davos is certainly one place to do it. McGwin notes that the major Arctic Frontiers gathering is taking place in Tromso, Norway, at the same time. I have attended that event several times in recent years. It is undoubtedly an important meeting with a scientific and a political section. But the global players gathered in Davos should, in principle, be able to exert far more influence when it comes to changing the economic and energy patterns which have been the basis for bringing about the climate change that is melting the Arctic.
Arctic melt – business opportunity?
The WEF also reaches wider media coverage, and, arguably, those who really need to change things. Preaching to the converted will not stop climate warming. McGwin quotes Gail Whiteman:
“Few outside the region have an idea of the role the Arctic plays, or the changes it is facing. Those that do tend to see the changes as an opportunity.”
This puts one of the key problems with Arctic climate change in a nutshell. Melting ice means easier access, more activity and thus higher risks for the fragile ecosystem – and ultimately, possibly more climate warming through increased emissions.
Professor Whiteman told McGwin:“We are at Davos to make the Arctic visible. Arctic change is at a critical point, and the kind of decisions that need to be made start at Davos.”
The organizers will also be circulating a petition asking Davos participants to contribute to a kitty to help fund an information campaign to keep decision-makers up to date on what is happening in the Arctic.
It seems the Arctic basecamp idea first came up at Arctic Frontiers in Tromso back in 2012. The Arctic Journal says Whiteman realized, during a discussion there, that people were very keen to get people in the boardrooms of companies to talk about the risk Arctic change was posing to their business. It dawned on Whiteman that the place to reach these people would be in Davos rather than Tromso.
At last year’s meeting, the WEF issued an Arctic Investment Protocol. Whiteman, worries that “once investors take an interest in the Arctic, they will see the opportunity but overlook the risk”.
If the message that “what happens in the Arctic doesn’t stay in the Arctic”is to sink in, McGwin concludes his article, then “what happens in Davos must not stay in Davos”.
Agreed, colleague. But, as we know, competition for public attention is fierce. Let us hope that the Arctic Basecamp will not be upstaged by the other events going on in the Swiss alps this week. And that the overall focus there “Responsive and Responsible Leadership”, and the need for international dialogue and concerted action rather than isolationism will still make the world headlines as the Trumpocene commences across the Atlantic.

“Cheers” to a cool Arctic in 2017
As 2016 draws to an end, the shortest day has passed in the northern hemisphere, and it should normally be a “cool” time of the year, in more ways than one, especially in the Arctic. But with temperatures at a record high, sea ice at a record low and feedback loops springing into action, the Arctic is hotting up – and I wish I could say the same for efforts to halt climate change.
Ice expert Jason Box tweeted this morning:
— Jason Box (@climate_ice) December 23, 2016
Meteorologist Scott Sutherland writes on Dec. 22nd:
“(…) North Pole temperatures have climbed to 30oC hotter than normal for this time of year.
(…) Now, in late December, in the darkness of the Arctic winter, air temperatures at the North Pole have actually reached the freezing point, as recorded by weather buoys floating within a few degrees of the pole. As of the morning of Thursday, December 22 (3 a.m. EST), the International Arctic Buoy Programme (IABP), operated out of the University of Washington, recorded temperatures from these buoy up to 0oC or slightly higher.”
“(…) Right now, Arctic sea ice extent is at the lowest level ever recorded.”
Arctic in need of tlc?
It looks like the Arctic is urgently in need of some tlc – or maybe intensive care would be more fitting.
The Arctic Report Card for 2016 recently published by NOAA should have set alarm bells ringing. Based on environmental observations throughout the Arctic, it notes a 3.5 degree C increase since the beginning of the 20th century. The Arctic sea ice minimum extent tied with 2007 for the second lowest value in the satellite record – 33 percent lower than the 1981-2010 average. That sea ice is relatively young and thin compared to the past.
A “shrew”d indicator of Arctic warming
Let me quote what are described as the “Highlights”:
“The average surface air temperature for the year ending September 2016 is by far the highest since 1900, and new monthly record highs were recorded for January, February, October and November 2016.
After only modest changes from 2013-2015, minimum sea ice extent at the end of summer 2016 tied with 2007 for the second lowest in the satellite record, which started in 1979.
Spring snow cover extent in the North American Arctic was the lowest in the satellite record, which started in 1967.
In 37 years of Greenland ice sheet observations, only one year had earlier onset of spring melting than 2016.
The Arctic Ocean is especially prone to ocean acidification, due to water temperatures that are colder than those further south. The short Arctic food chain leaves Arctic marine ecosystems vulnerable to ocean acidification events.
Thawing permafrost releases carbon into the atmosphere, whereas greening tundra absorbs atmospheric carbon. Overall, tundra is presently releasing net carbon into the atmosphere.
Small Arctic mammals, such as shrews, and their parasites, serve as indicators for present and historical environmental variability. Newly acquired parasites indicate northward shifts of sub-Arctic species and increases in Arctic biodiversity. “
Getting the message across
The NOAA website sums it up in a video, saying:
“…Rapid and unprecedented rates of change mean that the Arctic today is home to and a cause for a global suite of trillion dollar impacts ranging from global trade, increased or impeded access to land and ocean resources, changing ecosystems and fisheries, upheaval in subsistence resources, damaged infrastructure due to fragile coastlines, permafrost melt and sea level rise, and national security concerns.
In summary, new observations indicate that the entire, interconnected Arctic environmental system is continuing to be influenced by long-term upward trends in global carbon dioxide and air temperatures, modulated by regional and seasonal variability.”
Margaret Williams, the managing director for WWF’s US Arctic programme had this to say:
“We are witnessing changes in the Arctic that will impact generations to come. Warmer temperatures and dwindling sea ice not only threaten the future of Arctic wildlife, but also its local cultures and communities. These changes are impacting our entire planet, causing weather patterns to shift and sea levels to rise. Americans from California to Virginia will come to realize the Arctic’s importance in their daily lives.
“The science cannot be clearer. The Arctic is dramatically changing and the culprit is our growing carbon emissions. The report card is a red flashing light, and now the way forward is to turn away from fossil fuels and embrace clean energy solutions. Protecting the future of the top of the world requires us to reduce emissions all around it.”
Sack the teacher, kill the messenger?
That was her response to the Arctic Report Card. In my school days, the report card was a business to be taken seriously. A bad report meant you were in trouble and would have to smarten up your act or you would be in big trouble with mum and dad.
The question is – who gets the report, and who has to smarten up their act?
This one should make the governments of this world speed up action on mitigating climate change and getting ready for the impacts we will not be able to halt.
Then again, they could just try to get rid of the messengers who come up with the bad news. If your kid’s report card is bad, do you try to improve his performance – or get rid of the teacher who came up with the negative assessment – based on collected data?
I am concerned that the administration in the wings of the US political stage could be more likely to do the latter. As I wrote in the last Ice Blog post, the new Trump administration is threatening to cut funding for climate research. The proposed new Cabinet is well stocked with climate skeptics.
Concern about research
Financial support for the Arctic Report Card is provided by the Arctic Research Program in the NOAA Climate Program Office. Its preparation was directed by a “US inter-agency editorial team of representatives from the NOAA Pacific marine Environmental Laboratory, NOAA Arctic Resarch Program and the US Army Corps of Engineers, Cold Regions Research and Engineering laboratory.
Yereth Rosen, writing for Alaska Dispatch News, quotes Jeremy Mathis, the director of NOAA’S Arctic research program and one of the editors of the report card.
“The report card this year clearly shows a stronger and more pronounced signal of persistent warming than in any previous year in our observational record”.
“We hope going into the future that our scientists and researchers still have the opportunity to contribute and make possible the summary that we’re able to present. So we have every intention of continuing to publish the Arctic Report Card as we have in the past and pulling together the resources and the right people that allow us to do that”.
Livid and acrimonious
The debate over President Obama’s announcement that he was making a vast area of the Arctic Ocean off-limits to drilling for oil or gas, shows the dilemma of our times – and .. which could influence the living conditions on our planet for generations to come.
Erica Martinson, writing for the Alaska Dispatch News, provides interesting insights into the debate for those of us who do not live in Alaska.
She quotes Alaska’s Republican Congressman Don Young, saying he used “livid language” in his response. Obama’s move means “locking away our resources and wuffocating our already weakened economy”. He goes on “Alaska is not and shuld not be used as the poster child for a pandering environmental agenda”.
Ooh. Livid indeed.
She also quotes Republican Senator Dan Sullivan as describing the move as “one final Christmas gift to coastal environmental elites”. So would those be the indigenous communities being forced to relocate because climate changes are destroying their homes, Senator?
The administration, on the other hand, says it is protecting the region from the risk of a catastrophic oil spill, Martinson writes.
It seems to me that Obama’s parting gift goes rather to the “Alaska Native communities of the North Slope” who “depend largely on the natural environment, especially the marine environment, for food and materials”, and to the many endangered and protected species in the area, “including bowhead and fin whales, Pacific walrus, polar bear and others”.
What about the Paris Agreement?
But as well as that regional aspect, the decision not to open up new regions to drilling for oil and gas is in line with the global need to cut fossil fuel emissions to halt the warming of the world.
Jamie Rappaport Clark, CEO of “Defenders of Widife”, puts it:
“It marks the important recognition that we cannot achieve the nation’s climate-change goals if we continue to expand oil and gas development into new, protine environments like the Arctic and Atlantic Oceans”.
This is not just about Alaska, not just about the Arctic, but the future of the planet as a whole.
The World Meteorological Organization (WMO) says 2016 is on track to be the hottest year on record. According to UN estimates, the global temperature in 2016 was 14.88 degrees C – 1.2 degrees higher than before the industrial revolution began in the mid-19th century.
In an article for the New York Times on December 22, Henry Fountain and John Schwartz quote NOAA’s Arctic Research Program director Jeremy Mathis.
“Warming effects in the Arctic have had a cascading effect through the environment” “We need people to know and understand that the Arctic is going to have an impact on their lives no matter where they live”. That includes the oil-industry-friendly and climate skeptical team that is set to enter the White House in the New Year,
So when I propose a toast to a cool Arctic in 2017, I am not just thinking of my friends in the high north. For all our sakes, we have to kick our fossil fuel habits, save energy and cut the emissions which keep the giant refrigerator that helps make our world a viable place to live well chilled.
