Climate gerontology: meeting the challenge of population ageing and climate change.

The global population is ageing at a time when climate variability is increasing. It is argued that if we are to minimize the negative impact of environmental change on older people, interdisciplinary study of the convergence of the two trends, "climate gerontology", is needed. Climate gerontology can examine the unique challenges and needs of older people in coping with extreme weather events. It can contribute to our understanding of the everyday challenges of growing old in a changing climate and how we can achieve the "longevity dividend". In particular, it can lead the way to the development of effective policies to reduce the carbon footprint of people during their life course, protect older people from climate-related threats and mobilize their wealth of knowledge and experience to address these.
