Northern Climate ExChange

Information sources

Impacts

Northern natural systems and human communities will likely be stressed by the direct and indirect changes expected to be generated by climate change. More vulnerable systems may be negatively affected, while others may respond more positively to shifting climate norms and generate new opportunities for northern residents.

Below is a selection of articles and reference materials. For further information, you can search our Infosources Database or the online NCE Library.

Coastal zone

Sea-level rise, reduced ice cover on shorelines, and increased severe weather events may increasingly affect the coastal zone of the eastern and western Arctic through increased erosion and flooding.

Increased storminess

Cryosphere (snow, ice, and permafrost)

The cryosphere encompasses the frozen areas of the Earth, including snow, ice (lake, river, sea, and glaciers) and permafrost. These frozen areas are extremely vulnerable to the effects of a warming climate.

Ecosystem health

Climate warming will likely affect the distribution and habitat of terrestrial and marine Arctic species. Population densities of Arctic species are also likely to change in response to increasing stresses, food availability, and increasing competition from northward moving species.

Vegetation

Fish

Northern communities

A rapid change in the climate, ground conditions and biodiversity of the Arctic will have a subsequent impact on northern communities. The traditional knowledge, food sources, and the health of these communities may ultimately be affected.

Traditional ecological knowledge

Health

Country foods (environmental contamination of food, changing strategies for gathering food, shifting patterns in types of food consumed, etc.)

Economic development

Opportunities for economic development in the North may increase in a warming Arctic. Accessibility to remote areas will increase and working conditions will become less severe. Shifting temperature conditions and precipitation will also create challenges for industry that will require greater flexibility in future.

Forestry

Agriculture

Fisheries

Mining

Shipping

Tourism

Infrastructure

Climate change may affect the buildings, bridges, roads, and services provided to northern communities. Thawing permafrost may destabilize existing infrastructure and increase the possibility of the contamination of drinking water from a number of sources. Increased rates of coastal erosion and sea-level rise may also threaten the infrastructure of vulnerable coastal communities.
