Abstract:
Climate change is associated with shifts in global weather patterns, especially an
increase in ambient temperature, and is deemed a formidable threat to human health. Skin cancer,
a non-communicable disease, has been underexplored in relation to a changing climate. Exposure to
solar ultraviolet radiation (UVR) is the major environmental risk factor for skin cancer. South Africa is
situated in the mid-latitudes and experiences relatively high levels of sun exposure with summertime
UV Index values greater than 10. The incidence of skin cancer in the population group with fair skin
is considered high, with cost implications relating to diagnosis and treatment. Here, the relationship
between skin cancer and several environmental factors likely to be a ected by climate change in
South Africa are discussed including airborne pollutants, solar UVR, ambient temperature and
rainfall. Recommended strategies for personal sun protection, such as shade, clothing, sunglasses
and sunscreen, may change as human behaviour adapts to a warming climate. Further research and
data are required to assess any future impact of climate change on the incidence of skin cancer in
South Africa.
