A study by the Yale Project on Climate Change Communication on the public perceptions of climate change indicates that the majority of citizens grossly misunderstand the repercussions of climate change and its effects on health. The report shows analysis of results from a national survey conducted in October of 2014 and indicates that most US citizens have given little or no thought to the potential health effects of climate change.

Few Americans are aware of any current health consequences of global warming. When asked ‘In your view, what health problems related to global warming are Americans experiencing, if any?’ a majority either didn’t answer the question (43%) – which likely indicates they didn’t have an answer – or answered that they ‘don’t know’ (14%).  Only one in four (27%) named at least one health problem related to global warming, and 10% answered, incorrectly, that there are no health problems associated with global warming.

The health effects of climate change are very prevalent and encompass a wide range of issues. According to the World Health Organization climate change affects both social and environmental determinants of health, including clean air, safe drinking water, sufficient food and secure shelter. The WHO predicts that:

Between 2030 and 2050, climate change is expected to cause approximately 250 000 additional deaths per year, from malnutrition, malaria, diarrhoea and heat stress.

The United States Environmental Protection Agency also states that weather and climate change play a significant role in people’s health. Warmer temperatures lead to heat waves which lead to most heat-related deaths and play a part in spreading diseases and increasing water and air pollutants. Increased frequency in extreme weather poses immediate and severe threats to people in dangerous areas. The consequences can be life-changing and efforts towards solving the issue are dependent on various factors.

The impacts of climate change on health will depend on many factors. These factors include the effectiveness of a community’s public health and safety systems to address or prepare for the risk and the behavior, age, gender, and economic status of individuals affected. Impacts will likely vary by region, the sensitivity of populations, the extent and length of exposure to climate change impacts, and society’s ability to adapt to change.
