Welfare of Animals in Extreme Weather Events

Extreme weather events — heat domes, atmospheric rivers, tornadoes, and hurricanes — create acute welfare crises for wild, farmed, and companion animals at increasing frequency.

Key Facts

The 2021 Pacific Northwest heat dome killed an estimated 1 billion intertidal animals in a single event
Hurricane Katrina killed an estimated 250,000 companion animals and over 100,000 livestock
Tornado sirens and warnings do not trigger animal evacuation protocols in most jurisdictions
Farm animals in confined buildings are highly vulnerable to tornado damage and cannot self-evacuate
Wild animals displaced by extreme events often enter human-dominated landscapes creating conflict and welfare harm

Welfare Considerations

Extreme weather welfare responses require pre-event planning that is rarely done for animals. Farm animals cannot self-evacuate; companion animals require owner action; wild animals have no rescue system. The most effective welfare interventions are prospective: evacuation planning for livestock, companion animal emergency kits, and building standards that maintain structural integrity during extreme events. Climate mitigation reduces the frequency of events requiring these responses, making it the highest-leverage long-term welfare intervention.

What You Can Do

Create and practice a household emergency plan for all animals before extreme weather season
Advocate for farm animal emergency evacuation planning requirements in disaster preparedness standards
Support emergency animal rescue capacity in your regional disaster preparedness planning
Engage with climate advocacy organizations that incorporate animal welfare into their policy arguments
