Warm weather forcing rink operators to think artificial
An extended January thaw in parts of Quebec and Ontario has put a major dent in the outdoor hockey season. But an increasing number of municipalities, responding to fluctuating temperatures, are now using artificial refrigeration to keep their skating rinks frozen through the winter months. […] A study released last March said that outdoor hockey is being threatened by climate change. The study, co-authored by a McGill University professor Lawrence Mysak, said that ice rinks were opening later over and closing earlier in the year.
