Climate change and sea ice receding present new opportunities for mining, oil exploration and transportation in the Arctic. Climate change is affecting the circumpolar Arctic twice as fast as regions located in lower latitudes, bringing Arctic development to the forefront of the agenda as Canada begins its second chairmanship of the Arctic Council.
Arctic states are planning to bolster development and exploitation of the region by embracing an opportunistic development approach. The Arctic Council is transforming from a body concerned with environmental protection and sustainable development to one with a clear mandate to enhance economic cooperation. Last week’s Throne Speech from the Canadian government also emphasized the development of the Canadian North, with hardly a mention of conservation.
WWF supports the well-being of the Arctic’s indigenous communities,and development is necessary to create prosperity for the north. But when global warming is melting sea ice across the region, leading to increased Arctic accessibility, it is important to recall the Council’s original mandate of environmental protection and sustainable development. WWF is concerned by the recent narrowing of the Council’s sustainability remit to just one of its domains, the economy. Chief Gary Harrison from Arctic Athabascan Council said in Whitehorse yesterday that he doesn’t want the Council to evolve “from an environmental body to an extractive body.”
Arctic states are working towards the establishment of a circumpolar business forum and the Council’s new diplomatic mission to support businesses in Arctic development is important. This shift of focus on the Arctic circumpolar cooperative agenda must consider the balance between short-term development and the long-term sustainability of the region. There is a vast difference between the speed of industrial development and the progress on environmental protection. There is a risk that development will outpace conservation.
Positive signals are coming from United States officials that science will be central to the American chairmanship beginning in May 2015. Arctic states cannot afford to neglect protecting the Arctic environment, and they must take responsibility for the long-term functioning of rapidly changing Arctic ecosystems and live up to the original mandate of the Council.

Arctic ocean acidification: winners and losers

Today at the international conference on Arctic Ocean Acidification, we’re talking about socioeconomic issues. The increasing acidity of Arctic waters is a complex story where  some marine species will be winners (adapting and thriving) and others losers (to the point of extinction). As for humans, we stand to lose big –ocean acidification is likely to impact the abundance, productivity and distribution of Arctic fisheries.
More acidic Arctic waters will affect everything from the price of fish, to the cost of fishing, to the benefits of fisheries to the indigenous populations of the Arctic. With a multi-billion dollar fishing industry and a large subsistence population that relies heavily on ocean resources for the majority of their dietary protein, Alaska is particularly vulnerable. If ocean acidification takes the fisheries out of western Alaska where communities live on what the land and the sea provide, food security will become a serious challenge.
To buy some time and adapt to the changing chemistry of Arctic waters, it’s important to manage the other stressors impacting Arctic ecosystems. That means policies to counteract the effects of ocean acidification must consider other human impacts, like increased shipping in the Arctic.

 “A key solution is to help the Arctic ecosystems to help themselves by decreasing all the other pressures. We need to collaborate with the ecosystems”

– Sam Dupont, lead author of the biological chapter of the Arctic Ocean Acidification assessment of the Arctic Council
The services provided by ecosystems have real economic value.  Acidification means that the very chemistry of these ecosystems are changing rapidly. But by planning for marine ecosystems that can remain resilient in the face of rapid change, we can ensure that species adapt, and the people of the Arctic don’t lose out.

Arctic ocean acidification, the other CO2 problem

During the opening day of the conference on Arctic Ocean Acidification, I was bombarded by technical vocabulary like omega aragonites*, fracturation in alkalinity and biogeochemical cycling. The whole day was dedicated to explaining the changing chemistry of the Arctic Ocean. By changing the amount of CO2 in the atmosphere, we are actually increasing the acidity of the ocean without fully understanding the future impacts on Arctic marine ecosystems.
Many international bodies are enhancing their efforts to understand ocean acidification and there is a growing interest amongst decision-makers.
Political cycles and the 2008 financial crisis have hindered global climate agreement negotiations in the past few years. For the US and China, ocean acidification is an opportunity to rekindle the discussion on carbon from a new angle.
The chemistry of ocean acidification science is straightforward and certain– we know it is happening now and rapidly – faster than in the last 56 milion years and it will continue as we emit more CO2 to the atmosphere through burning fossil fuels.
However, we must still bridge a large gap between science and policy on acidification.The potential costs of inaction are high. Healthy oceans provide vital services to people, for example by buffering some of the atmospheric CO2 emitted by human processes. Acidification may also put fisheries, and therefore food security, at risk.
Carol Turley of Plymouth Marine Laboratory, a pioneer in this field of research, emphasized that even if we cannot predict the exact costs, casualties and damages related to acidification, scientific uncertainties are no excuse to not act. “If you mitigate (that is, reduce emissions of CO2 to the atmosphere) for ocean acidification, you also mitigate for climate change – so double gain and double the reason to act now.”

10 strong key findings flowing from this three year assessment were released today:

Acidification in the Arctic Ocean:

  • Arctic marine waters are experiencing widespread and rapid ocean acidification.
  • The primary driver of ocean acidification is uptake of carbon dioxide emitted to the atmosphere by human activities.
  • The Arctic Ocean is especially vulnerable to ocean acidification.
  • Acidification is not uniform across the Arctic Ocean.

Biological responses to ocean acidification

  • Arctic marine ecosystems are highly likely to undergo significant change due to ocean acidification.
  • Ocean acidification will have direct and indirect effects on Arctic marine life. It is likely that some marine organisms will respond positively to new conditions associated with ocean acidification, while others will be disadvantage, possibly to the point of local extinction.
  • Ocean acidification impacts must be assessed in the context of other changes happening in Arctic waters.

Potential economic and social impacts of ocean acidification on Arctic fisheries

  • Ocean acidification is one of several factors that may contribute to alteration of fish species composition in the Arctic Ocean.
  • Ocean acidification may affect Arctic fisheries.
  • Ecosystem changes associated with ocean acidification may affect the livelihoods of Arctic peoples.

* Aragonite is a material used by some sorts of sea creatures to build their shells. As ocean acidity increases, the ability of the sea creatures to build their shells from aragonite decreases, and so removes a valuable resource from food webs.

Arctic Ocean Acidification, from pteropods to walrus

I have always been fascinated by the effects of climate change on our planet. What is so interesting with the Arctic is that climate change occurs twice as fast in high latitudes in comparison with the rest of the world. This week I am in Bergen in Norway where I’ll find out  more about another effect of the excess of carbon dioxide in the air, ocean acidification. The Arctic Council is sponsoring a conference here on this threat to the Arctic Ocean.
Arctic Ocean acidification will lead to significant effects on sea life. Acidification impacts on Arctic marine life are affecting the abundance of organisms such as pteropods (small sea snails) which serve as a foundation for the Arctic food web. The increasing acidity of the water makes it harder for them to build shells. If we lose great numbers of these key species at the heart of Arctic Ocean food webs, then other animals such as walruses will also be threatened, with impacts on Arctic communities. These changes also threaten multi-million dollar Arctic fisheries.
It is increasingly clear from the scientific findings that immediate cuts in CO2 emissions are essential to slow the acidification of the Arctic Ocean. Knowledge about this environmental problem has expanded rapidly in recent years. WWF believes the research being discussed here this week should pressure the Arctic Council and its members to create a coordinated voice by Arctic states and observer states in global negotiations on climate change. As producers of much of the global supply of carbon dioxide pollution, the Arctic states and Arctic Council observers have an obligation to lead in these negotiations.
