Effects of Global Warming?

Environment Canada, who started keeping national temperature records in 1948, just reported that last winter was the warmest in modern Canadian history.

The average temperature of this unusual warm winter was 3.9° C above normal. In the corner where the Northwest Territories, Alberta and Saskatchewan meet, the temperatures were even 8° C (!) above normal.

Reason for this abnormal warm weather was – so Environment Canada – an unusual shift in the weather system that circulates cold Arctic air. This weather system is normally centered in the area of Hudson Bay, but this year the center was at the North Pole from where cold air could not spread across the country.
