Narwhals are enigmatic Arctic cetaceans whose welfare is threatened by climate change altering sea ice patterns, increased shipping, and subsistence hunting.
Wild narwhal welfare is increasingly compromised by the rapid transformation of their Arctic environment. Narwhals are among the most sensitive cetaceans to noise and human disturbance — icebreaker ships cause physiological stress responses and behavioral changes that disrupt feeding and communication. Rapid ice formation can trap narwhals in shrinking breathing holes — a prolonged, distressing welfare emergency for affected individuals. Climate-driven shifts in Arctic cod distribution alter narwhal feeding grounds, potentially causing nutritional stress. Subsistence hunting by Inuit communities is legal and managed, but welfare during traditional hunting methods is variable. The cumulative effect of climate change, increased shipping, and habitat alteration creates chronic welfare compromise for a species highly specialized for conditions that are rapidly changing.
