Animal Welfare Impact of Climate Change

Climate change is transforming the welfare landscape for billions of animals through habitat loss, food chain disruption, extreme weather, and disease spread. Understanding these impacts informs both mitigation and adaptation strategies.

Key Facts

Climate change is driving habitat shifts that force wildlife into novel environments with different food availability and predator communities
Coral bleaching events caused by thermal stress have killed large proportions of coral reef ecosystems affecting millions of fish species
Extreme weather events including heat waves, floods, and droughts cause acute mass mortality in wildlife
Phenological mismatches - timing shifts in prey and predator availability - create food security gaps for many species
Disease spread to new geographic areas exposes naive wildlife populations to pathogens without evolved immunity
Domestic livestock face increasing heat stress, disease burden, and feed insecurity as climate changes

Welfare Considerations

Climate change is arguably the largest emerging driver of animal welfare harm globally. The welfare consequences include acute suffering during extreme weather events, chronic stress from habitat degradation, starvation from food chain disruption, disease burden from novel pathogens, and displacement into unsuitable environments. Unlike most animal welfare problems, the scale of climate welfare impacts affects every ecosystem and every species. Addressing climate change is therefore one of the most impactful animal welfare interventions possible - alongside being essential for human welfare. The animal welfare community's engagement with climate policy is not a distraction from welfare work; it is one of its most important frontiers.
