Disabled people are highly susceptible to climate change impacts and disasters, yet they often remain sidelined or largely invisible. Policy makers, humanitarian agencies, and governments need to address the climate-related vulnerabilities that disabled people encounter during acute events and in the course of more creeping forms of climate change. As deaf researchers, we call for integrating disability justice into climate and disaster preparedness policies and practices worldwide. A disability justice approach can embrace the strengths that disabled people bring to disaster planning and climate mitigation and advocacy efforts. In this article we present case studies from different global regions to illustrate how disability is overlooked in responding to climate-related health impacts and disaster planning. We also draw particular attention to mutual aid networks led by disabled people in adapting to climate-related health impacts. We then suggest questions to help policy makers and practitioners integrate disability justice into their work. Above all, disabled people, organizations, and service providers should take ownership over the process of developing policies and actions to better prevent, prepare for, and respond to climate disasters.
