Climate Change and Animal Welfare Futures

Climate change is one of the most significant long-term threats to animal welfare globally, disrupting habitats, food webs and physiological tolerances across terrestrial and marine ecosystems.

Key Facts

The IPCC projects that 20 to 30% of species face significantly increased extinction risk at 1.5 to 2.5 degrees of warming
Coral reef bleaching events, driven by ocean warming, have killed over 50% of the Great Barrier Reef coral since 1995
Phenological mismatches — where animals hatch or migrate at the wrong time relative to their food sources — are increasing under climate change
Heat stress in livestock already costs billions annually in lost production and animal health impacts globally
Climate change is expected to increase the frequency and severity of extreme weather events affecting wildlife populations

Welfare Considerations

Climate change threatens animal welfare through multiple pathways simultaneously. Direct heat stress causes physiological suffering and death in extreme events. Habitat loss as climate zones shift eliminates the food, shelter and mates that animals need for adequate welfare. Phenological mismatches mean chicks hatch when their caterpillar food is past its peak, causing starvation. Sea temperature rise causes coral bleaching, destroying the habitat that thousands of fish species depend on. Marine acidification reduces the ability of shell-forming organisms to build their protective structures. The cumulative welfare impact of climate change on wild animal populations is enormous and demands that animal welfare advocates engage strongly with climate policy.

What You Can Do

Advocate for ambitious climate policy as an animal welfare priority alongside conservation arguments
Reduce personal carbon footprint including through dietary choices that reduce methane and land use emissions
Support wildlife adaptation to climate change through habitat corridor creation and species monitoring
Engage with climate organisations about the animal welfare dimension of climate impacts
Support research into climate-sensitive wildlife welfare monitoring and early warning systems
