We are at -4 degrees celsius.
A week ago we drove from Saskatoon in -38 degrees celsius weather. 34 degrees difference in temperature!
Now imagine awakening last week to just above freezing weather. The roads are starting to melt, slush is prevalent and birds are twittering.
Come back a week later. The same birds are seeking shelter from the 34 degree weather. Streams of melted snow are quickly receding and cracks appearing in the ground. Air conditioning units frequently stop and start.
How is it that in the middle of winter we can have 34 degree weather changes and the rest of the year that type of weather change creates havoc?
Another sure sign of the ability of people to acclimatize themselves to wherever they live (which may be an advertizement not to live in certain places??).
