Wolverines are uniquely vulnerable to climate change because their breeding depends on deep, persistent snowpack. Their welfare and conservation are deeply climate-linked.
Wolverine welfare under climate change illustrates the intimate connection between individual animal experience and environmental conditions at landscape scale. As spring temperatures rise, snow dens that protect newborn cubs from exposure collapse too early, killing cubs that cannot thermoregulate. Female wolverines making denning decisions face an increasingly hostile thermal environment. Fur trapping causes acute pain and prolonged suffering in trapped individuals. The remote wilderness the wolverine requires for its territorial behaviour is progressively diminished by human development. Individual wolverine welfare is thus a direct casualty of both climate change and habitat loss — two of the most important global conservation challenges.
