13．Outdoor ice hockey（冰球运动）is an important part in Canada's culture，but it could be history in parts of Canada within just a few decades，according to a new report．The report shows that warming temperatures have resulted in a noticeable decrease in the length of the skating season over the past half century．
The largest decreases in season length were observed in the prairies（大草原）and southwest regions of Canada．The researchers said outdoor skating may not be possible within the next few decades in areas such as British Columbia and Southern Alberta．Evidence of this was seen earlier this year when the world's longest skating rink（溜冰场），the Rideau Canal Skateway in Ottawa，was closed due to warmer-than-usual seasonal temperatures．
Their study，published in the journal Environmental Research Letters，calculated the annual start date and length of the outdoor skating season（OSS） from historical weather data across Canada，and recorded how these have changed since the 1950s with global warming．
"The creation of natural skating rinks depends on having enough cold winter days．It is hard to imagine a Canada without outdoor hockey，"said Damon Matthews，of Concordia University．"But I really worry that this will be a consequence of our continuing to ignore the climate problem and prevent international efforts to decrease greenhouse gas emissions（排放）．"
Using information from outdoor public ice skating rinks in various Canadian cities，the researchers created a set of weather criteria（标准）that marks the beginning，and determines the length，of the outdoor skating season．Their definition of the beginning of the outdoor skating season is the last in a series of three days where the highest temperature does not go above-5℃，since it takes several cold days to lay the initial ice on the rink．And then，the researchers counted the number of days when it is possible to flood the rink to create more ice to calculate the season's length at each of the 142 stations．
Canada appears to have taken more of a hit from global warming compared to other countries in the world．Since 1950，winter temperatures in Canada have increased by more than 2.5℃，about three times the globally-averaged warming．
