未来几十年户外溜冰的消失

The Canadian Geographer, July 16

Outdoor ice-skating is an important cultural pastime in many northern regions and holds a firm foothold in North American identity. Using citizen science data collected in six cities across Canada and the US, researchers estimated backyard skating conditions in past winters for which historical observations do not exist. They found that the number of high-probability skating days per winter is declining, especially in easternmost cities. Authors highlight the potential of public monitoring of these small, self-made outdoor rinks as a way to raise awareness on the impacts of climate change.
