Supporting informed decision making to improve resilience of the Rideau Canal Skateway to climate change effects

自1971年以来，每年冬天，国家首都委员会（NCC）都会把结冰的里多运河变成世界上最大的溜冰场。里多运河滑板道是一条长7.8公里的冰道，蜿蜒穿过加拿大首都渥太华。运河本身是加拿大国家历史遗址和联合国教科文组织世界遗产。最近的研究预测，到2050年，渥太华的冬天将缩短五周，低于-10°C的天数将减少35%。这样的变化将对里多运河滑板道产生严重影响。NCC和卡尔顿大学正在合作寻找解决方案。本研究将做以下工作：(1)完善当地天气、冰厚和积雪的知识基础；(2)评估滑板道对气候变化影响的脆弱性（如滑冰季节开始、冰厚）；(3)为NCC提供知识，以便在建立弹性和减轻气候变化对滑板的影响方面做出明智的决策。

Every winter since 1971, the National Capital Commission (NCC) has turned the frozen Rideau Canal into the world's largest skating rink. The Rideau Canal Skateway is a 7.8-km ice path winding through Ottawa, the capital of Canada. The canal itself is a National Historic Site of Canada and a UNESCO World Heritage Site. Recent studies predict that, by 2050, winters in Ottawa will be five weeks shorter, with 35% fewer days below -10 °C. Such changes will have serious impacts on the Rideau Canal Skateway. The NCC and Carleton University are teaming up to look for solutions. This study will do the following:(1) improve the knowledge base on local weather, ice thickness and snow cover;(2) assess the Skateway's vulnerabilities to the effects of climate change (e.g. start of the skating season, ice thickness); and(3) provide knowledge for the NCC to make informed decisions on building resilience and mitigating climate change effects on the Skateway.
