The Arctic Region A Brief Overview

The polar regions are the icy areas around the North and South Pole. The Arctic and Antarctic are in the polar regions. Polar bears, penguins, seals,

Typically, our poles serve to cool the Earth. If the poles begin to warm, our “cooling system” breaks down. Example: Polar ice reflects sunlight. If this.

How could the Arctic be affected by global warming?

Know Know – the Artic is being affected by Global Warming Understand Understand – the impacts of global warming on the Inuit community Skills Skills – exam practice, analysing information, note taking Know Know – the Artic is being affected by Global Warming Understand Understand – the impacts of global warming on the Inuit community Skills Skills – exam practice, analysing information, note taking D Describe the effects of global warming on the Arctic B-C Categorise and explain the impacts of global warming on the Arctic region A* - A Evaluate the effects of global warming on the Arctic to consider whether global warming will bring more benefits than problems

Where? The ice sheet at the North Pole (sea ice), and the northern parts of eight countries (land ice) How could the Arctic be affected by global warming? 1.Canada 2.Greenland 3.Russia 4.USA (Alaska) 5.Iceland 6.Norway 7.Sweden 8.Finland

What has happened because of global warming? How could the Arctic be affected by global warming? The amount of permanent sea ice decreased by 14% between 2004 and 2005 At the current rate of ice melt, it is predicted that % of Arctic ice will be lost by 2100.

Less ice cover in the Arctic region The ice melts at a faster rate. A greater quantity of heat is produced Less solar radiation is reflected away and more is absorbed by the ocean Is this a positive or negative feedback on the climate? Why?

Key terms Tree line Tundra Permafrost Boreal forest a)Northern coniferous forest. b)Permanently frozen ground. c)The edge of a habitat within which trees will grow. d)Ecosystems in Arctic areas. How could the Arctic be affected by global warming?

Investigate the social, environmental and economic impacts of global warming on the Inuit using the worksheet and text book Pages How could the Arctic be affected by global warming?

Environmental Impacts Short Term Medium Term Long Term Socio-Economic Impacts on Inuits Short Term Medium Term Long Term Benefits of Global Warming? Short Term Medium Term Long Term Ihe impacts of global warming on the Arctic- Use pages in the textbook to find out the information below. Ensure that you include specific detail. Consider whether the impacts are short, medium or long term.
