Map: Annual temperature change, by ecoprovince, 1948 to 2016

Description for Map

The title of this map is “Annual temperature change, by ecoprovince, 1948 to 2016.” This map provides a visual representation of the average change in annual temperature in Canada, by ecoprovince, over the time period from 1948 to 2016.

On the page, there is one large map of Canada, a legend to the upper right and a scale bar below. The map delineates ecoprovinces with a thin black boundary line and ecoprovinces are labeled with a code. Fine black dashed lines show provincial and territorial boundaries. Below the map, ecoprovince codes and their corresponding names are listed for reference.

The map indicates the change in temperature over time symbolized by a colour gradient from yellow to red to black. Less change is indicated by shades of yellow and orange, and more change is indicated by shades of red to black.

The unit of measurement is degrees Celsius (°C). The legend contains seven categories of temperature change: 0 to less than 1 (yellow), 1 to less than 2 (light orange), 2 to less than 3 (orange), 3 to less than 4 (red-orange), 4 to less than 5 (crimson red), 5 to less than 6 (burgundy) and 6 to less than 7 (black).

The map shows that the area of Canada that has experienced the greatest temperature increase between 1948 and 2016 is the northwest, with the largest increase experienced by ecoprovinces along the Yukon–Alaska border and in the Northwest Territories.

Notes: Temperature change (1948 to 2016) refers to the linear trend of temperature departures from the 1961 to 1990 climate normal. Caution should be exercised when analyzing change results in the North because of lower climate station densities. Significance levels are not available.
