Arctic ice melt Canada's top weather concern in 2007

The "shocking" record loss of Arctic sea ice was Canada's top weather event in 2007, Canada's environment ministry said Thursday. Each year for the past 12, Environment Canada has published a list of the top 10 climate or weather phenomena to impact Canada that year.
 
For 2007, "the dramatic disappearance of Arctic sea ice -- reported in September -- was so shocking that it quickly became our number one weather story," the ministry said in a statement.
