Canadian Regional Geography Part 5: The Far North
The Far North also called The Territorial North
Provinces: Yukon, Northwest Territories & Nunavut
→ 39% of Caadas area
→ 0.3% of Caadas populatio
→ 0.5% of Caadas GD
Nordicity
→ Measurement of degree of ortheress
→ Combination of 10 human & physical variables for a quantitative measure of northerness
o 1) Latitude
o 2) Summer Heat
o 3) Annual Cold
o 4) Types of Ice
o 5) Annual Precipitation
o 6) Natural Vegetation
o 7) Accessibility by Land & Sea
o 8) Accessibility by Air
o 9) Population
o 10) Economic Activity

Document Summary
Canadian regional geography part 5: the far north. The far north (cid:894)also called (cid:858)the territorial north(cid:859)(cid:895) (cid:862)the last frontier(cid:863): to be conquered in canada. Largest urban centres: whitehorse (26,888, yellowknife (19,231) Higher proportion of indigenous people in north. 1) limited biodiversity: hard time recovering from human activity. Ice reflects sunlight: dark surfaces absorb sunlight, global warming melts ice lowers albedo ground absorbs more solar radiation. Permafrost = soil zone that remains permanently frozen for two or more years. Thawing permafrost emits carbon dioxide and methane, while lowering albedo & increasing soil microbial activity. Northern climate becomes more temperate, the geographic range of boreal forest is predicted to shift north. Greatly reduce the size & extent of arctic biomes, endangering countless species of vegetation. Fragile ecosystem with low species diversity and slow recovery rates. 23% reduction in sea ice over the past 20 years. 1) reduction in hunting grounds: summer & winter ice cover diminishes.
