Final Answer:
Nunavut primarily has a polar climate, also known as an arctic climate. This type of climate is characterized by long, very cold winters and short, cool summers.
Step-by-step explanation:
In the polar climate, the average temperature for the warmest month is below 10°C (50°F). This climate results in a landscape that is mostly covered with ice and snow for the majority of the year.
Factors affecting Nunavut's climate include its high latitude, its location in the Arctic, and its interaction with polar ice, the Arctic Ocean, and atmospheric circulation patterns.
The polar climate leads to a unique ecosystem, where only the hardiest of plant and animal species can survive. Human activities are also significantly constrained by the extreme conditions.
