In 2006, reduced thickness of ice roads forced the Diavik Diamond Mine in Northern Canada to fly in fuel rather than try to transport cargo across melted pathways, at an extra cost of $11.25 million.
The mountain pine beetle outbreak in British Columbia—fueled by higher winter temperatures that allow insects to survive—expanded in recent years to be 10 times greater than any previously recorded outbreak in the province. Mortality rates of sockeye salmon, meanwhile, have increased because of higher water temperatures in the Fraser River.
These examples are among many in Canada's national climate assessment—an overview from the national government of existing climate science affecting the country. It also includes government and industry adaptation activities, such as new electricity forecasts for hydropower because of projected water flow shifts.
While focused on Canada, the overview holds relevance for global industries, such as oil sands developers potentially affected by floods and shippers traversing Canadian waterways, analysts say.
The report released by Natural Resources Canada—a third national assessment of climate impacts in the country—also provides more detail than a regional chapter on North America in the Intergovernmental Panel on Climate Change documents released this year.
