The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. Indicators of Temperature change in Canada show the yearly and seasonal surface air temperature departures for the years 1948 to 2018. As well, they present a spatial distribution of surface air temperature departures for the year 2018. An annual departure (or anomaly) is the difference between the value for a given year and a baseline value. The baseline values used in these indicators are the annual and seasonal temperature averages for the reference period of 1961 to 1990 (often referred to as the 1961–1990 normal). The Temperature change in Canada indicators help show how Canada's surface air temperature has changed since nationwide recording of consistent and comparable climate observations began in 1948. Information is provided to Canadians in a number of formats including: static and interactive maps, charts and graphs, HTML and CSV data tables and downloadable reports. See supplementary documentation for data sources and details on how those data were collected and how the indicators were calculated.
