Wolverines are highly cold-adapted carnivores that depend on persistent spring snowpack for denning. Climate-driven snow loss threatens their reproductive welfare and long-term survival.
Wolverine welfare is intimately linked to snow conditions. Female wolverines in reduced snowpack areas show failed reproduction — young kits die when dens melt prematurely. Adults face nutritional stress as access to cached food and carrion changes with snow conditions. As wolverines are pushed to higher elevations, habitat fragmentation increases and road collision risks grow. Climate change represents a slow-moving welfare catastrophe for this charismatic species with limited ability to adapt.
