All of Canada’s coasts, the longest in the world, are being impacted by changing climate, and these impacts will continue to increase in the future. It is an ice that distinguishes Canada's about 176,000 kilometres of North coastline from the Pacific and Atlantic coastlines. Authors of the new report, published by the Government of Canada, have found that both, sea ice and ground ice within the permafrost, are very vulnerable to the global warming.
Many parts of the Beaufort Sea can see up to a metre of coastline lost each year due to erosion. But places that are rich in ground ice or exposed to high energy waves can have losses of up to 20 metres of coastline in a single year. Coastal communities like Tuktoyaktuk, Kimmirut and Arctic Bay are already suffering from coastline erosion and flooding. Another danger is related to the potential change of the coastal ecosystems and available fish stock as a result of warming water along the North coast, what may have negative impact on commercial fishing. All provinces and territories within Canada’s coastal regions have specific adaptation strategies or plans that include reference to coastal issues. Read more at http://www.cbc.ca/
