Problem
The average temperature of the atmosphere over both land and sea has been gradually rising over the past century. Greenland, the world's largest Island, is mostly covered by glaciers, some as much as 3.2km (2 miles) thick. Key contributing factors to the melting of Greenland's glaciers, as well as to long-term global climate change, are processes caused primarily by human activity. If left unchecked, these factors will have harmful and lasting effects on global ecosystems and the services they provide.
a) What evidence is there that ice in Greenland is melting at an unnaturally fast rate?
b) Which human activities are likely to be contributing to the melting ice in Greenland?
c) How might your activities specifically be contributing to the melting ice in Greenland?
d) Why is melting ice problematic from an environmental standpoint?
