Cryosphere: Zoom in on the Arctic
The Arctic is currently warming two to three times faster than the global average and is expected to warm more than any other region on Earth. SLCPs contribute to increased melting in the Arctic, and BC deposited on snow...

Applicability of space technology to Arctic policy areas
This figure maps the contribution that each type of space system (communications, weather and climate, navigation, earth observation, surveillance, and science) can make to each policy area (safety, environment, sustaina...

Boundaries of the Arctic Council Working Groups
When defining Arctic regions, it is understood that no single, clear cut boundary exists to delineate their extent. Rather, this boundary will change with its application: environmental, biological, economic, jurisdictio...

Transport routes of POP and concerned areas
Persistent organic pollutants (POPs) mainly Polychlorinated Biphenyls (PCB) and hexachlorocyclohexane (HCH), are brought into the Barents region and the whole of the Arctic region from many different locations.

Dominating air currents
The pollution from industrialized nations are affecting the environment in the Arctic region. The main areas of indutrial activity in the northern hemisphere are spreading to specific areas in the Arctic though air curre...

The Arctic region - definitions
Several definitions of the Arctic, physical temperature boundaries, political boundaries, such as as the CAFF delineation, and the Arctic Circle. Compiled by GRID-Arendal and presented in the CAFF Habitat Conservation Re...

Arctic, AMAP and CAFF area
Identifying and defining the Arctic is not necessarily obvious, as this map illustrates. The Arctic Council working groups on conservation and pollution operate with slightly different definitions due to both practical a...

Major wilderness areas in the Arctic
The Arctic covers around 33.5 million km2 and holds the largest continuous expanses of unfragmented wilderness in the world, outside of Antarctica. Indeed, seven of the ten largest wilderness areas in the world outside A...

Shift in climatic zones, Arctic scenario
The scenarios from the Arctic Climate Impact Assessment (ACIA) project that temperatures will increase dramatically in the Arctic, more than in many other parts of the world. This leads to effects, such as the decrease o...

Arctic development scenarios, human impact in 2050
Human activities influence the environment and reduce the value of forests, tundra and plains in terms of original biodiversity and habitat. Primarily larger mammals are hit by the fragmentation caused by roads and pipel...

Mean snow-cover extent in the Northern Hemisphere 1966-2006
Snow occurs predominantly on the northern continents, on the sea ice of the Arctic Ocean and on Antarctica. On the Northern Hemisphere continents, snow covers a maximum mean area of 45.2 million km2, typically in January...

Northern Sea Route and the Northwest Passage compared with currently used shipping routes
Climate models project that summer sea ice in the Arctic Basin will retreat further and further away from most Arctic landmasses, opening new shipping routes and extending the navigation season in the Northern Sea Route ...

Population and main oil and gas production areas in the Arctic
The Arctic represents one of the least populated areas in the world, with only sparse settlements and very few large cities and towns - in comparison with e.g. continental Europe. The largest cities are in Northwest Russ...

The Arctic Ocean
The Arctic Ocean experiences much less exchange with the atmosphere than other oceans; momentum exchange (wind drag), heat exchange and freshwater exchange are limited due to the sea ice cover.

Invasive species response to climate change - Hydrilla spp, current and 2080 habitat suitability
As climate change alters Arctic ecosystems and enables greater human activity, biological invasions are likely to increase in the Arctic. To some extent, Arctic terrestrial ecosystems may be predisposed to invasion becau...
