As discussed in other chapters of this report, several aspects of the impact that human activities have on the ecosystem are clearly manifested and visible or will likely become so in the near future (see chapters General background description of the ecosystem - Ecosystem interactions - Human impact; Current and expected state of the ecosystem - Human activities /impact and Current and expected state of the ecosystem - Conclusions about state of the ecosystem). Other aspects may become visible longer time into the future, and this is the topic of the present chapter.

Air temperatures have increased almost twice as fast in the Arctic than the global average over the last 50 years. Models predict that air temperatures will continue to increase considerably, and summer sea ice in the Arctic will disappear before the middle of this century and winter sea ice by the end of the current century. Because of the complex dynamics of the Barents Sea ecosystem, and becaus...

According to the ICES criteria (ICES 2008b) the stocks of NEA cod, NEA haddock, northern shrimp (Pandalus borealis) and capelin have full reproductive capacity and are harvested within sustainable limits. The stocks of NEA Greenland halibut (Reinhardtius hippoglossoides), golden redfish (Sebastes marinus) and deep-sea redfish (Sebastes mentella) have been fished down to very low levels. These thre...

The IPCC Fourth Assessment Report (AR4) undertook an evaluation of the evidence for and impacts of anthropogenic change worldwide where they concluded that human-induced climate change was occurring (IPCC, 2007). As part of the IPCC process, the results from several Ocean-Atmosphere Global Circulation Models were presented. The performance of 20 models for different Arctic regions, including the...

Primary production and zooplankton
The disappearance of seasonal sea ice will result in increased primary production in the Barents Sea (Øiestad, 1990; Loeng et al. 2005, Ellingsen et al., 2008). The disappearance of seasonal sea ice would eliminate the ice-edge blooms, which would be replaced by blooms resembling those in the more productive Atlantic waters and their timing would be determined by...
