Climate Change and Wildlife Welfare: Emerging Impacts

Climate change is creating welfare challenges for wildlife including heat stress, food source disruption, range shifts into unfamiliar territories, and increased disease. These impacts are accelerating as warming continues.

Key Facts

The 2022 IPCC report projects that 3-14% of species face extinction with 1.5°C warming, rising to 18% at 2°C.
Coral bleaching events — driven by ocean warming — are occurring 5 times more frequently than in the 1980s.
Arctic animals including polar bears face acute welfare impacts from sea ice loss reducing hunting success.
Phenological mismatches — species changing their timing at different rates — disrupt food webs affecting millions of animals.
Disease range expansion driven by warming allows pathogens like avian malaria to reach new host populations.

Welfare Considerations

Climate change is becoming one of the most significant drivers of wildlife welfare harm globally. Heat stress events cause mass mortality in species from flying foxes to seabirds. Starvation from prey disruption affects predators from orca to polar bears. Range shifts force animals into unfamiliar territories where they face competitor species and unsuitable habitat. Disease exposure causes immune challenges for which populations have no evolved resistance. The welfare harms of climate change are occurring now and will intensify without emissions reductions, making climate action one of the most impactful interventions for wildlife welfare.
