Climate Change and Health

An Overview of Climate Change

The Earth’s climate in not static, it has always varied naturally, slowly cycling between ice ages and inter-glacial periods as a result of natural causes. Nowadays, the term “climate change” is used in relation to the future expected climate change and the change in climate over the last few centuries. During this time, global temperature has risen much more rapidly than in previous cycles. The rapid change is mostly attributable to the increase in greenhouse gases in the atmosphere in recent years; largely a result of the burning of greater quantities of fossil fuels, deforestation and changes in farming methods. The scientific consensus is that global temperature will continue to rise throughout the twenty first century; however the extent of the increase depends on the future emissions of greenhouse gases.

The effects of climate change are very broad and include rising sea levels, increased extreme weather events, changes in food and water availability, changes in biodiversity and effects on health.

Effects on Health

Climate change is capable of influencing the health of the population in many different ways, both mentally and physically. Worldwide, one of the largest health effects is likely to be malnutrition, followed closely by a rise in the number of people affected by malaria, diarrhoeal diseases and natural disasters. The effects in the UK are likely to show a different pattern, with a change in the seasonal distribution of deaths likely to have the largest impact. Increases in food and water borne diseases can also be expected along with higher skin cancer incidence. A rise in the number of floods and heatwaves could increase physical and mental stress amongst the population.

The Effects of Climate Change on Health in the West Midlands

Between October 2009 and March 2010 a Defra funded report was put together with the intent on providing in depth information of the extent of climate change in the West Midlands and the effects that climate change could have on the Region’s health up until the 2080s. The document includes an investigation into:

  • The direct effects of temperature on health
  • Climate change, air pollution, respiratory diseases and allergens
  • Climate change, food, water and vector borne diseases
  • Climate change, indoor environments and health
  • Climate change, ultra-violet radiation and health
  • Impacts of extreme weather events on health
  • Climate change and health inequalities
  • Recommendations for adaptation strategies
