Upper limit for sea level projections by 2100

Abstract: We construct the probability density function of global sea level at 2100, estimating that sea level rises larger than 180 cm are less than 5% probable. An upper limit for global sea level rise of 190 cm is assembled by summing the highest estimates of individual sea level rise components simulated by process based models with the RCP8.5 scenario. The agreement between the methods may suggest more confidence than is warranted since large uncertainties remain due to the lack of scenario-dependent projections from ice sheet dynamical models, particularly for mass loss from marine-based fast flowing outlet glaciers in Antarctica. This leads to an intrinsically hard to quantify fat tail in the probability distribution for global mean sea level rise. Thus our low probability upper limit of sea level projections cannot be considered definitive. Nevertheless, our upper limit of 180 cm for sea level rise by 2100 is based on both expert opinion and process studies and hence indicates that other lines of evidence are needed to justify a larger sea level rise this century.

Personal interviews in cultural consumer research – post‐structuralist challenges

Abstract: This paper takes a post‐structuralist perspective on consumer research and discusses the role of personal interviews in cultural analysis. It problematizes the use of the phenomenological interview in cultural consumer research, arguing that the underlying research paradigm, existential‐phenomenology, is not necessarily adequate for cultural analysis because it focuses attention primarily on the individual and the first‐person experience. Such a paradigmatic perspective is problematic because it tends to sustain a view of human agency that is highly individualistic and thus fails to account for the cultural complexity of social action. Overall, the paper contributes to the further development of the post‐structuralist approaches to postmodern marketing thought. Post‐structuralist ideas and assumptions challenge the central principles of modern marketing and consumer research in many ways and it is the aim of the paper to contribute to a better understanding of the methodological implications that they entail.

Reviews and syntheses: Changing ecosystem influences on soil thermal regimes in northern high-latitude permafrost regions

Abstract: . Soils in Arctic and boreal ecosystems store twice as much carbon as the atmosphere, a portion of which may be released as high-latitude soils warm. Some of the uncertainty in the timing and magnitude of the permafrost–climate feedback stems from complex interactions between ecosystem properties and soil thermal dynamics. Terrestrial ecosystems fundamentally regulate the response of permafrost to climate change by influencing surface energy partitioning and the thermal properties of soil itself. Here we review how Arctic and boreal ecosystem processes influence thermal dynamics in permafrost soil and how these linkages may evolve in response to climate change. While many of the ecosystem characteristics and processes affecting soil thermal dynamics have been examined individually (e.g., vegetation, soil moisture, and soil structure), interactions among these processes are less understood. Changes in ecosystem type and vegetation characteristics will alter spatial patterns of interactions between climate and permafrost. In addition to shrub expansion, other vegetation responses to changes in climate and rapidly changing disturbance regimes will affect ecosystem surface energy partitioning in ways that are important for permafrost. Lastly, changes in vegetation and ecosystem distribution will lead to regional and global biophysical and biogeochemical climate feedbacks that may compound or offset local impacts on permafrost soils. Consequently, accurate prediction of the permafrost carbon climate feedback will require detailed understanding of changes in terrestrial ecosystem distribution and function, which depend on the net effects of multiple feedback processes operating across scales in space and time.

Limits and Possibilities of the Arctic Council in a Rapidly Changing Scene of Arctic Governance

Abstract: In a very short time, discussions on Arctic governance have moved from being a topic of scholarly attention and NGO advocacy onto the agendas of states and of the European Union (EU). Increasingly, the various alternatives propounded by a diverse set of actors over what Arctic governance should look like appear as pre-negotiation tactics, a type of testing period before a regime change. The article examines whether the still predominant inter governmental forum, the Arctic Council, is facing a threat of being supplanted by other forms of governance. It will study how resistant the Arctic Council, and its predecessor the 1991 Arctic environmental protection strategy, are to change in order to understand whether the council could renew itself to meet future challenges. It will also examine the various proposals for Arctic governance set out by states, the EU and the region’s indigenous peoples. All this will permit conclusions to be drawn on where the Arctic Council stands amid all these proposals and whether, and in what way, it should change to support more sustainable governance in the Arctic.
