Arctic Climate
Fun Facts
Sea Ice

Water freezes in the high latitudes including the Canadian arctic cover 7% of the Earth's surface. These large iceblocks some three meters thick or more float or are attached the coast of a landmass. The white color reflects solar radiation and reduces the heat absorbed by the ice.

Figure 1: Map of Canadian Climate Regions

The Canadian Arctic is composed of generally four differnt climate regions as shown in the map above. The most dominat district is the Arctic tundra. The Artic tundra is slow evolving due to the cold temperatures. Human interactions strongly effect this delicate ecosystem. When explorations are done careful consideration of the flora in this area are of the legal protection the Canadian government has enforced to preserve this habitat. Studies have shown also that the global temperature is rising due to the pollution produced at increasing rates.

This region is cold and receives high levels of precipitation. Permafrost is the dominant feature in the arctic with the exception of the northern coast of the Yukon Territory which is under sea permafrost. Maps are provided below for a better understanding of where permafrost exists in Canada.

To learn more about the permafrost mointors click on the map to be linked to the Geological Survey of Canada. Permafrost is permanently frozen ground. This occurs in cold climates and is sensitive to slight changes in rising global temperatures. The permafrost has an active layer that melts and freezes with the change in temperature that supports the delicate tundra vegetation.
