Welfare and conservation of wolverines (Gulo gulo) in the context of climate change reducing snowpack, examining how deep snow dependency affects individual survival, reproduction, and population viability.
Wolverine welfare is inextricably linked to winter climate conditions in a way that makes them one of the clearest indicators of climate change impacts on wild animal welfare. Each wolverine kit that dies because spring snow melted before independence — a welfare harm that is invisible, untreated, and unmeasured — represents a direct consequence of global greenhouse gas emissions. Climate change is not an abstract conservation threat for wolverines; it translates into individual suffering through reproductive failure, nutritional stress from disrupted food caching, and the ultimately fatal reduction of a species' viable range. Protecting wolverine welfare requires both immediate habitat protection and the broader climate action that slows the warming trend threatening their snowpack dependency.
