Historical observations of annual mean surface temperature show that the rate of surface warming for Canada (slope of the blue line) is more than twice the rate of surface warming for the globe (slope of the red line). The rate of warming for the Canadian Arctic (slope of the grey line) is about three times the global rate. Canadian results are based on the Adjusted and Homogenized Canadian climate data (Vincent et al., 2015). The global result is based on the HadCRUT data set (Morice et al., 2012).
