Exposure to Climate Variability

The indicators of exposure to climate variability refer to the probability of a climate-related health hazard occurring. This section presents information related to six climate outcomes which have the potential to impact health. Indicators of exposure can help us understand what climate-related impacts are occurring in our area and the areas that are most susceptible to particular impacts. Exposure informs our understanding of overall vulnerability when considering the sensitivity and susceptibility of our populations, and the climate-related health outcomes reported.

This section includes information on the following climate related outcomes which have the potential to impact health:

Extreme temperatures

  • Extreme heat
  • Extreme cold

Extreme weather

Air quality: Climate change has the potential to impact air quality through the distribution of pollen as a result of longer growing seasons, and the increasing temperatures impacting ozone levels. Poor air quality can contribute to the following health concerns: cardiovascular disease, cancer, stroke, respiratory illnesses, mental illness (e.g. depression), and premature death.

Contamination and availability of food and water

  • Blue green algae

Vector borne disease: With a changing climate, warmer temperatures are expected to increase the distribution of vectors and the risk and transmission of vector borne diseases.

Exposure to ultraviolet radiation

  • Ultraviolet radiation exposure (UVR) is not currently monitored by SMDHU. For more information on UVR exposure and the UV index, please visit the Environment Canada webpage.
