Summer 2007 was warmer than normal



    Climate Trends and Variations Bulletin for Summer 2007

    OTTAWA, Sept. 14 /CNW Telbec/ - The summer of 2007 in Canada was not the
warmest on record but temperatures were still higher than the norm.
Information on the summer weather-that-was is from Environment Canada's
Climate Trends and Variations Bulletin. It provides a cross-country look at
temperatures and precipitation for the summer 2007 season and compares it to
climate data from the past 60 years.

    Highlights from The Climate Trends and Variations Bulletin for Canada
include:

    
    - Summer 2007 in Canada was the 7th warmest on record, with temperatures
      0.9 degrees C above normal (based on preliminary data). Most of the
      country experienced temperatures less than 1degrees C above normal,
      with northern parts of Nunavut having temperatures more than
      1 degrees C above normal. The warmest summer in Canada was recorded in
      1998, with temperatures at 1.8 degrees C above normal. The coolest
      summer was recorded in 1968, with temperatures 0.8 degrees C below
      normal.

    - The climate region in Canada with the highest above-normal temperature
      this summer was recorded in the region covering most of Nunavut
      (+ 1.4 degrees C). The southern Ontario and southern Quebec region
      experienced the lowest above-normal temperature, this summer
      (+ 0.4 degrees C).

    - Nationally averaged seasonal temperatures have been at or above normal
      during the last 10 years, with only the springs of 2002 and 2004
      experiencing below normal temperatures (from summer 1997 to
      summer 2007).

    - Overall, this summer was the 28th wettest on record in Canada, with
      precipitation at 2.9% above normal. The wettest summer was in 2005,
      with precipitation 21.2% above normal. The driest summer was in 1958
      with precipitation 14.3% below average.

    - The climate region covering most of Nunavut experienced its second
      wettest summer (28% above normal), whereas the region covering the
      southern half of the Prairie Provinces had their 7th driest summer
      (26.6% below normal).
    

    Because weather conditions can vary greatly from one year to the next due
to natural variability, it is difficult to attribute this past season's
weather to a specific cause. However, in many respects, these conditions and
associated impacts are consistent with what scientists predict will happen
more frequently as the world becomes warmer as a result of climate change.
