Resumo de Recurso
The Arctic - climate change
Socio-economic Impacts
Shrinking sea ice could open new shipping routes.
New natural resources may be exploited
Possibility of undiscovered oil and gas reserves
May lead to conflict over which countries own them
Warmer climate and soils = more agricultural opportunity
Thawing permafrost can result in collapsed buildings and broken pipelines.
Ecological Impacts
Changing climatic regions means habitats are being reduced or lost.
Some areas have a sensitive ecosystem, the loss of one species could have devastating effects.
For some areas the number and diversity of species may increase as sea ice coverage is reduced and the temperatures increase.
Vulnerability
Low capacity to cope.
Impacting many areas of Arctic life.
Environmental Impacts
Melting of Greenland Ice Sheet
Injection of fresh water in to the sea, changes density of water and could disrupt ocean currents.
Thawing permafrost releases CO2 and methane.
Contributes further to global warming.
