Study Notes

Northwest Passage

The Northwest Passage is a sea route through the Arctic Ocean, sought after for its potential to shorten shipping routes between Europe and Asia.
Conflicts over the Northwest Passage arise from differing interpretations of sovereignty and navigational rights in Arctic waters.

Sovereignty in the North

Sovereignty is the supreme authority over a territory or a region and is central to Canada's claims in the Arctic.

Arctic Seasons

Arctic seasons are extreme due to the high latitude and the tilt of the Earth's axis.

Climate Regions

Arctic regions experience very cold, dry climates.

Factors Affecting Climate (LOWERN)

Latitude, Ocean currents, Winds, Elevation, Relief, and Near water.

Arctic Tundra Region

Soils are thin, nutrient-poor, and slow-draining.
Vegetation is low-growing, adapted to cold, dark winters.

Permafrost

Permafrost is permanently frozen ground, which affects the soil, vegetation, animal life, and human infrastructure in the Arctic.

Climate Change

Climate change is long-term changes in weather patterns, driven by natural processes and human activities.
The "Greenhouse effect" is a natural process where gases trap heat in the atmosphere.
Global warming is the increase in Earth's average temperature due to the greenhouse effect, amplified by human activities.

Permafrost Carbon Feedback

The melting permafrost releases stored carbon, which contributes to greenhouse gasses and further global warming.

Climate Impact on the North

Climate change impacts the North faster and more significantly than other parts of the world.
Melting permafrost affects the land and infrastructure, and the release of greenhouse gasses by the thawing soil.

Arctic Climate Factors

Climate

Very cold, dry climates due to high latitude and lack of direct solar radiation.
Factors affecting climate include LOWERN (latitude, ocean currents, winds, elevation, relief, and nearness to water).

Latitude

High latitude results in long, dark winters and short, cool summers.

Ocean Currents

Ocean currents influence temperature and precipitation patterns, impacting the north's climate.

Winds

Prevailing winds, such as the westerlies, affect temperature and precipitation patterns.

Air Masses

Air masses influence temperature and precipitation based on their origin and characteristics.

Near Water

Proximity to water moderates the climate, impacting temperature and precipitation.

Seasons

Extreme seasons due to Earth's tilt and high latitude; long, dark winters and short summers.

Climate Region

Tundra climate.

Soil

Thin, nutrient-poor, and slow-draining permafrost soils.

Vegetation

Low-growing vegetation, adapted to cold, dark winters.

Permafrost and Carbon Feedback Cycle

Melting permafrost releases stored carbon, accelerating global warming. This impacts the landscape (e.g., sinkholes, damaged infrastructure) and human life (e.g., housing, transportation).

Climate Graph Analysis Example

Analyze specific data, including temperature range, average annual temperature, total precipitation, and average annual precipitation.
Identify the location in Canada using data.
Recognize potential climate factors, such as LOWERN, that impact the region's climate, including proximity to water, latitude, elevation.
Examples of information taken from a graph: Average Winter Temperatures, Summer Temperature Ranges, Total precipitation in mm.
