1 Canadian Shield The Climate
-The climate varies throughout the regions of the Canadian Shield. When you travel further north, the winters and the cold weather becomes increasingly longer. -The Canadian Shield faces a very dry climate all year long with each season giving little rainfall.  -The Canadian Shield is closer to the Arctic, which is colder than most regions of North America, which explains why the winters are much longer than the summers. The summers though, are warm.   -Most of the weather that the Canadian shield experiences comes from the Arctic. -The Canadian Shield is warmest during the day, while much colder at night time. The climate is very dry, not enabling many plants to grow here. The temperatures are too low at times for plants to survive as well. -The southern region of the Canadian Shield gets only 300mm mm on rainfall and snow every year on average. -North has even less; with less than 300mm on both rain and snow each year on average.

2 Canadian Shield Topography
-During the Ice Age, glaciers removed most of the soil, leaving a barren rock surface in many places. -The retreat of the glaciers affected the drainage of the Shield to a significant degree. -The Shield consists of a chaotic pattern of rivers, lakes, swamps, and muskeg. The average elevation of the Shield is about 100 meters above sea level in the north, rising to about 500 meters in the south. -The center of the Shield is much lower in elevation than its outer portion. -The Canadian Shield's oldest bedrock is up to 1200 million years old. Its mountains and shape was shaped by the earlier glaciers.                                                                       -The volcanic belts that still exist today are now nearly flat plains. -Many lakes evenly spread out through the land are the because of young watersheds. -The land of the Canadian Shield yields some of the oldest volcanoes on the planet.  -Glaciers in the past were the ones responsible for shaping the landforms of the Canadian Shield. -The Canadian Shield is also the Earth's biggest area exposed to Achaean rock.

3 Canadian Shield's Vegetation
-There is alot of vegetation on and around the Canadian Shield. Most of it is Boreal Forest. -Boreal forest covers most of the Shield, there are alot of types of trees that grow here like spruce, pine, and fir. Some deciduous trees like the white birch tree are also there. -These trees are little and powerless and are more likely to go to the pulp and paper industry than to lumbering. -No trees can grow north of the tree-line because the growing season is to short and too little precipitation along with the permafrost. --These trees can survive in these conditions because they are able to withstand the cold weather. -Not too many plants can survive in the conditions closer to the north, because the cold and dry climate doesn't support the vegetation growth, especially further north.  -Trees that grow here are popular for their materials to make paper, since they are fragile.

4 Impact from Global Warming
-Canada's Arctic's snow and ice has been increasingly melting after the Cold War. The Northwest Passage would be opened if it continues to melt at a faster rate. Animals such as polar bears and other inhabitants of the Arctic are unable to hunt and live in this place up north if all the ice melts. -The dry climate of the Canadian Shield is not necessarily helping the growth of plants such as the Boreal Forests. -The north is suffering the lack of plant growth not only because of the climate, but also because of the pollutants in the air not enabling plants normally supposed to grow in cold weather to grow. -The warmer climate from global warming enables plants further in the south of the Canadian Shield to grow, and harvests can even be made, just like Greenland took advantage of it. -If it ever grows colder, the ice in the Arctic will restore, and Canadians may even end up starving if it gets even colder, but the Arctic''s wildlife will benefit from that. -The economy from harvests and farming may be less successful, due to the soil being too dry and the Canadian Shield not having enough precipitation. -The areas that are affected by global warming can support the forestry, but the warmer climate from global warming lead to certain bugs being able to survive in even the cold weather. Certain bugs burrow into the trees and end up destroying the bark and wood, used for many materials such as paper.

5 British Columbia's Approach to battling Global Warming?
-BC is currently tackling at 40% of greenhouse gas emissions out of the total amount that we produce. -Establish legislation to reduce greenhouse gas emissions. -British Columbia developed the "Cap and Trade" system to ensure that large industries and aviation reduced greenhouse gas pollution. -Strong caps were put for pollution produced. Caps are to be below 33% below 2007 levels by 2020. -Pollution permits are put up for auctions. The auction money goes to the province for going green projects to reduce greenhouse gas emissions. -West Coast Environmental Law is advocating for laws that encourage renewable energy, but in a way that does not undermine environmental values. -One of the biggest issues now facing local governments is climate change. This project aims to provide innovative direction for local governments to respond effectively to the global climate crisis.
