Major transformation is currently underway in atmospheric, oceanic and cryospheric environments in the Canadian Arctic. Climate change has drastically reduced the volume of sea ice in the circum-Arctic, while in terrestrial environments glaciers are melting. Coastal environments, where watersheds, glaciers, meltwater, floating ice and ocean interact, are also changing rapidly. Climate warming has already altered the thick ice at Canada's northernmost coast. Vast ice shelves that have existed along the north coast of Ellesmere Island for thousands of years have lost 50% of their areal extent in break-up events over the last decade.

目前，加拿大北极地区的大气、海洋和冰冻圈环境正在发生重大变化。气候变化大大减少了环北极地区的海冰体积，而在陆地环境中，冰川正在融化。流域、冰川、融水、浮冰和海洋相互作用的沿海环境也在迅速变化。气候变暖已经改变了加拿大最北端海岸的厚冰。沿着埃尔斯米尔岛北海岸存在了数千年的巨大冰架在过去十年的破裂事件中失去了50%的面积。
