Acid Arctic Ocean and Russell Brand?
Is ocean acidification a term you are familiar with? If you are a regular Ice Blog reader, I would like to think you will be. But I am prompted to ask this question because the term came up during a discussion at a weekly evening class I attend, and I was flabbergasted that none of the people there had a clue what it meant. These were all university-educated professionals. That means we in the media have our work cut out for us explaining how climate change is making the seas more acidic, and why this is something we should be worried about.
This incident has reminded me that we journalists have to avoid assuming that everyone is familiar with the terms we use in our coverage on a regular basis. Climate change is the kind of topic where you want to reach a specialist audience, but also the vast majority of the population. We all have to change our habits to reduce CO2 emissions, and we all have to vote for the politicians who have the responsibility for energy and environment policy. That means we need to talk about the problems in a way everybody understands.
I am encouraged to see the BBC website had a longer article on the threat of ocean acidification a few days ago. I don’t think it has made its way into the tabloids though, correct me if I am wrong.
I was made very aware of the issue during a trip to Arctic Spitzbergen in 2010 with a team of scientists monitoring just what happens to the life forms in the sea when it becomes more acidic because it is absorbing so much of the CO2 we emit. The polar regions are suffering more than others, as cold water absorbs CO2 faster.
Towards the end of last year, I interviewed Professor Alex Rogers from the University of Oxford, who is also the scientific director of the International Programme on the State of the Oceans, which had just published a major study on acidification.
Listen to the interview:
He told me: “The oceans are taking up about a third of the carbon dioxide we’re producing at the moment. While this is slowing the rate of earth temperature rise, it is also changing the chemistry of the ocean in a very profound way.”
Carbon dioxide reacts with sea water to form carbonic acid. Gradually, this makes oceans more acidic.
Threat to marine life
Sea water is already 26 percent more acidic than it was before the onset of the Industrial Revolution. According to the IPSO report, it could be 170 percent more acidic by 2100.
Over the last 20 years, scientists around the world have been conducting laboratory experiments to find out what that would mean for the flora and fauna of the oceans. Ulf Riebesell of the Helmholtz Institute for Ocean Research in Kiel, a lead author of the report, conducted the world’s first experiments in nature, off the coast of the Arctic island of Svalbard in 2010. This was the project I visited.
Giant test-tubes were lowered into the ocean 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. The experiments showed that increasing acidification decreases the amount of calcium carbonate in the sea water, making life very difficult for sea creatures that use it to form their skeletons or shells. This will affect coral, mussels, snails, sea urchins, starfish as well as fish and other organisms. Scientists say some of these species will simply not be able to compete with others in the ocean of the future.
Hard times for coastal residents
All this will have severe economic and social consequences. Ultimately, acidification will affect the food chain. Tropical and sub-tropical areas with warm-water corals are going to suffer. Coral reefs are home to numerous species, serve as nurseries for fish and are a valuable tourist attraction. They also protect coastlines against waves and storms.
At the same time, the polar regions are suffering more than others, as cold water absorbs CO2 faster. Riebesell told me the experiments in the Arctic indicate that the sea water there could become corrosive within a few decades. “That means the shells and skeletons of some sea creatures would simply dissolve.” What a horrific prospect.
The Antarctic is already affected. IPSO’s Alex Rogers told me: “We’re seeing instances where we’re finding tiny shelled molluscs, tiny snails that swim in the surface of the oceans, with corroded shells.”
These creatures play a key role in the marine food chain, supporting everything from tiny fish to whales. “One of our primary sources of marine-derived protein is in rapid decline,” says Monty Halls, manager of the UK-based Shark and Coral Conservation Trust. He describes ocean acidification as the “most serious threat to our children’s welfare.” Monty is working to produce video and cartoon material to interest the younger generation in the need to change our behavior to protect marine life.
Two German scientists Antje Funcke and Konstantin Mewes have written and illustrated a children’s story called Tipo and Tessi to make kids aware of the need to protect the ocean. So far, it has only been published in German. The English translation is available, but so far there is a lack of funding for publication.
Vicious circle of climate change
Scientists are also concerned about a feedback effect that will further exacerbate global warming. In the long run, the ocean will become the biggest sink for human-produced CO2, but it will absorb it at a slower rate. That means the more acidic the ocean becomes, the less capacity is has to act as a buffer.
Alex Rogers sees a further problem: “Carbonate structures actually weigh down particular organic carbon. In other words, they help carbon to sink out of the surface layers of the ocean into the deep sea. Anything that interferes in that process can potentially accelerate the rate of CO2 increase in the atmosphere.”
And that would be very dangerous. “The rates of CO2 increase we are seeing at the moment are probably as high as they’ve been for the last 300 million years,” says Rogers.
The IPSO scientists draw an unsettling comparison between conditions today and climate change events in the past that have resulted in mass extinctions. They say a lot of these major extinction events occurred in connection with high temperatures and acidification, similar effects to the ones that we are experiencing today.
The BBC article I mentioned earlier also mentions new research by scientists at Exeter University, indicating that increasing acidity creates conditions for animals to take up more coastal pollution, like copper. That would mean not only creatures with calcium-based shells would be endangered.
Find a celebrity champion?
The experts stress that it is not too late to halt the acidification process, although the CO2 will remain in the oceans for thousands of years. This brings me back to the topics of recent Ice Blog posts: the UN climate negotiations and the need for urgent action. And of course, to the mention in the title above of the British comedian Russell Brand. This relates to another issue I have been writing about recently: the question of celebrity involvement and whether that can help inform people about and interest them in topics like climate change and the acidification of our oceans. My commentary on this, with regard to Leonardo di Caprio at Ban Ki-moon’s September summit in New York, sparked some interesting discussions.
Just this morning I was reading about Russell Brand and how his new book calling for a revolution on all kinds of issues is attracting huge interest. I have noticed that people otherwise completely uninterested in politics and social issues are at least paying some attention because their favourite comedian is talking about them. Maybe we have to get Russell Brand on board. I’m not sure what kind of action he would advocate, but there would certainly be a lot fewer people who could say they’d never heard of ocean acidification.

It is with a heavy heart that I write this first blog post since my holiday, catching up with the latest climate news. A piece by Alex Kirby of Climate News Network drews my attention to the fact that temperatures in Barrow, Alaska, one of the first places to feature on the Ice Blog when it was created in 2008, have risen by an astonishing 7°C in the last 34 years (looking at the average October temperature). As Alex Kirby puts it, “an increase that, on its own, makes a mockery of international efforts to prevent global temperatures from rising more than 2°C above their pre-industrial level”. We need more climate action

The Arctic on the UN agenda
To those of us who deal with the Arctic on a regular basis, the significance of the melting ice for the UN climate negotiations and vice versa is abundantly clear. But not everybody understands all the connections. A major media event like this week’s New York climate summit hosted by the UN Secretary General Ban Ki Moon in person was a fine chance to focus attention on the need to protect the Arctic. Greenpeace made good use of it, handing over a petition with six million signatures just ahead of the big event, and with hundreds of thousands gathered in New York for the Climate March.
It was timely in more ways than one, just as the latest sea ice figures were published to confirm the melting trend.
The petition calls for long-term protection of the Arctic, with the region warming more than twice as fast as the global average and opening the high north to shipping and commercial exploitation. Greenpeace and other groups are calling for a ban on oil exploration, which could endanger the fragile ecosystem. Experts also have safety concerns about increased shipping.
Commercial development versus environment
Earlier this month, a survey showed that 74% of people in 30 countries support the creation of a protected Arctic Sanctuary in the international waters surrounding the North Pole. The study was commissioned by Greenpeace and carried out by Canadian company, RIWI. Around the same time, the Arctic Council, which combines the Arctic states and indigenous peoples’ representatives, currently chaired by Canada, supported the founding of a new business grouping, the Arctic Economic Council. Its aim is to promote the commercial development of the Arctic region. I wrote about this here on the Ice Blog and on the DW website.
Global responsibility for the Arctic
The UN Secretary General accepted the Greenpeace petition saying:
“I receive this as a common commitment toward our common future, protecting our environment, not only in the Arctic, but all over the world.”
Ban Ki-moon said he would consider convening an international summit to discuss the issue of Arctic protection. He also expressed a desire to travel aboard one of the organisation’s campaigning ships in the Arctic in the near future.
Greenpeace Executive Director Kumi Naidoo, who was part of the delegation, said: “The Arctic represents a defining test for those attending the summit in New York”.
He said leaders should bear in mind that concern for the rapid warming of the world was not consistent with planning oil and gas development in the melting Arctic.
The small delegation that met Ban Ki Moon included Indigenous rights activist and Saami politician Josefina Skerk, who last year trekked to the North Pole to declare the top of the world ‘the common heritage of everyone on earth’.
Skerk, a member of the Saami Parliament, said: “We, who want to continue living in the North, are gravely concerned about climate change and the destructive industries that are closing in. My people know and understand the Arctic, and it is changing in a manner, which threatens not just our survival, but the survival of people all over the world.”
Skerk said humans had created the crisis and had to take action to solve it.
“I urge the Arctic countries in particular to take a giant step up and I think the world needs to pay much closer attention to ensure that it happens. They might as well start here in New York.”
From Kiribati to Svalbard and New York
Melting ice especially from the Arctic Greenland ice sheet is raising sea levels around the globe, endangering low-lying areas. At the weekend, the President of Kiribati, Anote Tong, ended a Greenpeace-organized tour of glaciers in Norway’s Svalbard Archipelago. He said the trip to the Arctic ice had made a deep impression on him, which he would share with world leaders at the U.N. climate summit:
“It’s a very fascinating sight. In spite of that, what I feel very deeply is the sense of threat,” Tong said. “If all of that ice would disappear, it would end up eroding our shores.”
Kiribati is a group of 33 coral atolls located about halfway between Hawaii and Australia. Many of its atolls rise just a few feet above sea level.
In last year’s report by the Intergovernmental Panel on Climate Change (IPCC), experts concluded oceans could rise by as much as 1 meter (3.3 feet) by the end of this century if no action is taken to cut the greenhouse gas emissions causing global warming.
“It won’t take a lot of sea level rise to affect our islands,” Tong said. “We are already having problems.”
Sea ice minimum confirms melting trend
The New York summit coincides with the annual announcement of the minimum sea ice for the year, as the summer season comes to an end. The sea ice – in contrast to glaciers on land – does not influence global sea level, but is regarded as a key indicator of how climate change is affecting the region. This year the figure announced by the US National Snow and Ice Data Centre (NSIDC) was 5.01 million square kilometers. The figure is the sixth lowest extent since records began.
The minimum ever recorded at the North Pole was 3.29m sq km in 2012 – and the eight lowest years have been the last eight years.
Ice levels in the Arctic have recovered from their all-time low, but are still on a shrinking trend, said Julienne Stroeve of the National Snow and Ice Data Centre. ”We have been telling this story for a long time, and we are still telling it,” she said.
NSIDC records showed that, this year, ice momentarily dipped below 5million sq km to 4.98m on 16 September, but the official figure is taken from a five day average.
Satellite data shows that one part of the Laptev Sea was completely clear from sea ice for the first time this summer. One of the most important questions for climate scientists is how soon the Arctic will experience its first sea ice-free summer.
Rod Downie, head of WWF UK’s polar programme, said that this year’s new Arctic minimum should prompt new action from the leaders meeting in New York. He stressed the connection between the Arctic and weather conditions in other parts of the world:
“As David Cameron prepares to meet other global leaders at the UN climate change summit in New York, the increased frequency of extreme weather that is predicted for the UK as a result of a warming Arctic should serve as a reminder that we need urgent action now to tackle climate change,” he said.
The summit was a major PR event to draw attention to the need for urgent and substantial climate action. The accompanying protests around the globe show people are not happy with the slow pace of the climate talks and their governments’ efforts to reduce emissions. Of course there was little in the way of concrete pledges. Still, on the whole, I see it as a successful step on the way to a new climate agreement because it has put the spotlight on climate change at a time where international conflicts are dominating the news agenda.

UN Climate Chief on New York summit
Your Ice Blogger has been busy with the New York climate summit around the corner. I was delighted to read that Ban Ki Moon is considering a special Arctic summit and a trip on a Greenpeace Arctic mission vessel after receiving a petition to Save the Arctic. I am also hoping there will be some high-profile promises of climate action.
Meanwhile, here in Bonn, I talked to Christiana Figueres, the Executive Secretary of the UNFCCC (Climate Secretariat), which is based here in Bonn, just next door to my Deutsche Welle Office, before she left for New York.
She told me what she expects of this meeting, which is something different from the regular UN climate summits. She also told me why she was joining yesterday’s climate march.
Let me share some excerpts from the interview in writing here with you, and offer you a full length audio version of my talk to this very influential and passionate lady.
More on the climate summit and the Arctic here soon.
Excerpts from my interview with Christiana Figueres:
Ice Blogger: Why do we need yet another climate summit?
The conferences we organize once a year have the purpose of moving towards a legally based agreement, scheduled to be adopted in Paris next year. In New York, nothing is going to be negotiated. It’s very much an attempt to blow wind into the sails of the formal process. It’s about raising political will and public awareness. It is a powerful opportunity for the leaders of countries and corporations to come forward and say what each of them is going to do.
UN Secretary-General Ban Ki-moon has asked these leaders to bring bold announcements and actions to the summit. What do you expect to come out of it?
We will have a host of announcements from governments about what they are already doing and will undertake with respect to bringing down their own emissions and increasing the resilience that they need to incorporate into their planning and their infrastructure to deal with the variability and the vulnerability of climate change. From the private sector we expect the same: announcements as to how they are going to contribute to reduce emissions, either in their own operations or, even more interestingly, how they are going to be shifting their capital into low-carbon services and products to accelerate the global shift towards a low-carbon economy.
Are you expecting major announcements by the host country USA or a key player such as China?
Yes, we are expecting all countries to come forward and begin to put on the table what they will be able to contribute next year into a much more formal setting. But for that, the deadline is not until March 2015. What we expect is indications of what is possible. The fact is that most countries around the world are currently doing their homework and figuring out at a national scale what is financially, politically, economically and technically possible for them to do.
The summit is taking place in the USA, a key player in terms of emissions and a possible new climate agreement. Can hosting the summit there make a difference to US attitudes and policy?
The second term of President Obama has seen an accelerated and up-scaled engagement on climate change. The latest move of the Obama administration to ask the EPA (US Environmental Protection Agency) to come forward with regulations on power plants is probably the most ambitious action the US government has taken on climate change. We expect President Obama will be giving indications of how the United States is going to further build on those efforts. It is also very interesting that on US land, there will be the people’s climate march, just two days before the summit. That will show that there is, even in the United States, broad and deep public support for global climate policy making.
Do you think this kind of grassroots movement is what we need to take things forward?
I think it’s a very important component. I’m very grateful to the organizers of the march and to everyone who’s going to be at the march. I will be there, because it’s important to give a very strong message that it is not just the responsibility of governments or corporations, but rather there is also civil society responsibility here to make their awareness and concern felt, and encourage countries and companies to move towards low-carbon economies as soon as possible.
Some people say cities and regions should play a bigger role while governments struggle to negotiate a climate agreement?
Well it’s not an either or. Cities all around the world have already taken a very impressive lead. And we will hear from them. The mayors of hundreds of cities will be in New York, and the same goes for regions, whether it’s groups of countries or groups of municipalities. The optimization of climate action is going to come from the coherent integration of policy from the international level to the national to the local level.
Isn’t it difficult to arouse interest in an additional climate summit in the current world political situation with attention focused on conflicts in the Middle East, Ukraine and other places?
The whole week in New York will see much press attention to the summit. Not only because we will have hundreds of thousands of people on the street, not only because we will have hundreds of political leaders there, hundreds of corporations, but because they are all coming to New York for one very powerful reason. That is, climate change is now the biggest challenge that humanity has faced, certainly in this century. And there is growing awareness of this. There is already a lot of conflict around the world, around water scarcity, around migration, around food and security, and that is exacerbated by climate change. So if we want to prevent conflicts that will scale out of control, then we have to address climate change in a timely fashion.
The latest figures show greenhouse gas emissions are still rising. Scientists say the two degree target is virtually out of reach. What has to happen to bring about the kind of action we need to avert disastrous climate change?
Science has made it very clear: there is only one pathway that will allow us to stay under the maximum two degree maximum temperature increase which is the maximum temperature increase we could allow, and still maintain a more or less predictable climate for all populations around the world. So this summit and the formal processes which will occur in Peru at the end of this year and in France at the end of next year are three very important clarion calls to world leaders both public and private that time is running out. We still have the time to do it, but in order to avert the worst effects of climate change, we have to come to a global agreement by next year.

Arctic Economic Council – and the environment?
I would like to share my thoughts with you on the founding meeting of the Arctic Economic Council, taking place in Canada Sept. 2nd and 3rd. Iqaluit, the capital of the northern Canadian territory of Nunavut, is hosting the inaugural meeting of the, group set up to promote commercial development in the Arctic, as climate change makes the region more accessible. It was in Iqaluit that the first-ever ministerial meeting of the Arctic Council (AC) took place back in 1998. The newly established independent Arctic Economic Council (AEC), with close links to the AC, could prove to be equally influential.
Canada currently holds the rotating presidency of the Arctic Council, an organization linking eight Arctic states and six organizations representing Arctic indigenous peoples. Its self-set tasks include sustainable development, monitoring the Arctic environment, identifying pollution risks and environmental emergency preparedness. But in the race to open the Arctic to increased shipping, oil and gas exploration and mining, the formation of the new Arctic Economic Council (AEC) could see commercial interests gaining the upper hand.
Canada puts business first
Leona Aglukkaq, Canada’s Minister for the Environment, the Canadian Northern Economic Development Agency and the Arctic Council, is presiding over the founding meeting of the AEC. Its creation has been a key project during Canada’s 2013-2015 Arctic Council chairmanship, which Aglukkaq has focused on “development for the people of the North.”
“Our government prioritized the creation of the Arctic Economic Council to facilitate business opportunities, trade, investment and growth in the best interests of Northerners,” said Aglukkaq ahead of the two-day meeting. “Establishing this body is an historic moment for the Arctic Council in its efforts to advance sustainable development in the Arctic. I’m confident that the AEC will be a strong and effective body that will help enhance pan-Arctic economic cooperation for the benefit of communities and people in the Arctic.”
An unwise move for the AC?
But some people believe the AC could be making a mistake by allowing a potentially highly influential business group to grow outside of its own structures. Neil Hamilton, Senior Polar Political Advisor at Greenpeace International, told DW: “By creating an independent organization which answers to no one but has the authority to attend, work within, and manipulate the activities of the Arctic Council and its working Groups, the Arctic Council has severely undermined its own mandate.”
The AEC is being established with the contribution of the Arctic Council, but as an independent body. Representatives of both Councils would meet at regular intervals to discuss the economic development of the Arctic.
Originally, the AEC was envisaged as a circumpolar business forum. It’s since turned into a more formal structure. Each of the member states and each of the council’s indigenous permanent participant organizations was invited to send a maximum of three representatives to the inaugural meeting, where they will discuss the organization, structure and objectives of the AEC. The business representatives attending include CEOs and other high-ranking figures from a range of industries including oil and gas exploration, iron mining, tourism and shipping lines.
In the future, membership will not be limited to these nominations and may accept self-nominations from the Arctic business community.
A back-seat for the environment?
Canada says businesses in the Arctic will play a strong role in building a sustainable and economically vibrant future for the region. This will not reassure environment campaigners who have repeatedly attacked the current Canadian administration for its support of environmentally problematic industries such as oil tar sands or fracking, and for its refusal to back international climate agreements. The participation of the Vice-President of Russia’s Rosneft Oil Company Andrey Shishkin will raise eyebrows among those concerned about the possible environmental impact of oil exploration in the High North.
Finland is seeking to chair the AEC, although the group is to be purely business and not government run. In a press release, the country’s Foreign Ministry mentions environment protection but does not appear to give it priority when it outlines the objectives of the new body:
“In the future, the main focus of its work will be on the enhancement of the economic operating conditions of indigenous peoples and Small and Medium Enterprises (SMEs), the reduction of obstacles to trade, the support for sustainable economic operations, and raising of issues the AEC itself considers topical.”
In an AC paper on “facilitating the creation of the Arctic Economic Council,” environmental protection is only listed the last of six objectives, in connection with “maximizing the potential for Arctic economic activities.”
Conservationists are concerned that protecting the environment could take a back seat while companies pressure for fewer restrictions. With the Arctic warming more than twice as fast as the rest of the world and melting ice easing access to northern regions, the pace of Arctic development could outrun efforts to ensure environment protection and safety measures with increasing shipping and the risk of accidents or oil spills.
The World Wildlife Fund, which originally supported the group, told journalists the way it had been set up was “opaque and unaccountable”. WWF said it hat been refused permission to observe the meeting.
Greenpeace Arctic policy advisor Hamilton told DW: “The founding document of the Arctic Economic Council sets the frame for a new era of exploitation of the Arctic, without any indication of intent to protect the environment.” At the same time the Arctic Council, which was established to protect the environment, was “negating its prime function.”
Hamilton called on the Arctic Council to accord civil society the same privilege as it appears to be allowing the new economic group, by loosening regulations on granting the role of observer status.
The two-day meeting in Iqaluit ends on Wednesday, September 3rd. In the coming months, the Arctic Council will have to clarify its relation to the new AEC it helped create, and demonstrate how it’s going to reconcile the increasing pressure for commercial activity with avoiding environmental damage.
