Climate Change and Animal Welfare

How climate change is already causing welfare harms to billions of wild animals and what this means for conservation and welfare planning.

Key Facts

Climate change is altering species distributions, food availability, and phenological timing at rates that exceed adaptation capacity for many species
Extreme heat events cause direct mortality in wild animals through hyperthermia and cardiac stress
Drought reduces prey and food availability, causing starvation deaths in predators and herbivores alike
Ocean warming and acidification impair marine animal physiology including coral bleaching that destroys reef fish habitat
Wildfire frequency and intensity increases due to climate change cause direct injury and death and destroy habitat
Climate-driven disease emergence exposes naive populations to novel pathogens without evolved immune defense
Phenological mismatch — when migration, breeding, and food availability fall out of synchrony — causes starvation in breeding birds and mammals

Welfare Considerations

Climate change is not just a conservation crisis — it is one of the largest sources of ongoing animal suffering in the world, causing mortality and distress at scales that dwarf most human-caused welfare harms. Heat stress, starvation, dehydration, disease, injury from extreme weather events, and the chronic physiological stress of environmental disruption affect billions of individual wild animals. This welfare framing complements the conservation framing: protecting ecosystems from climate disruption prevents both the loss of species and the suffering of the individual animals that compose those populations. The urgency of climate action is therefore both a conservation and an animal welfare imperative.
