Wild Animal Welfare in Climate Change

Climate change is emerging as one of the most pervasive sources of welfare harm for wild animals, altering food availability, habitat quality, disease range, and extreme weather events that affect billions of individuals.

Key Facts

Temperature increases alter the timing of food availability relative to breeding seasons in many migratory species
Coral bleaching events kill the reef ecosystems that support millions of fish and invertebrate species
Drought and wildfire events kill millions of individuals directly through starvation and burning
Disease vectors including ticks, mosquitoes, and parasites expand into new ranges with warming
Phenological mismatches between insect emergence and bird breeding reduce chick survival in documented cases

Welfare Considerations

Climate change is a welfare emergency for wild animals at global scale. Individual animals experiencing habitat degradation, food scarcity, and extreme weather events suffer real welfare consequences that multiply across billions of individuals. The timescales of climate change mean that welfare harms are ongoing and accelerating rather than discrete events. Addressing climate change is therefore one of the most consequential welfare interventions available, albeit one that operates through political and social systems rather than direct welfare management.
