Document Summary
Lecture 11 - climate of the territorial north. Much of the area is officially classified as a desert because precipitation is less than 250 mm per year. Summers are short and snowfall is possible at any time of the year. In the southern more populated parts of the region, daytime high temperatures often exceed. Much of this region is located north of the arctic circle (the 66. 50n line of latitude) What is the significance of this line: any location north of it will experience at least one day in a year when the sun does. Dec 5, 2016 not rise and at least one day when the sun does not set. The aurora borealis are commonly seen at night. Temperatures are expected to warm more in polar regions than any other regions on earth. Implications: forecasted ice-free summers in the arctic ocean and hudson bay by 2050, a reduced population of polar bears and caribou.
