The climate regions of Canada are illustrated in Map 1.1 or 2.5.
2.
A linear (least square) trend over the period of record.
3.
Difference from the normal temperature.
4.
This column ranks 2007 temperature departures over the period between 1948 and 2007. For example, the Atlantic Canada Climate Region had a departure that was 0.1°C warmer than the long term temperature average, which ranked the 2007 season as the 26th warmest over the 60 year period.
5.
90% confidence interval obtained by a nonparametric technique.
6.
Not statistically significant.
