The Interplay of Climate Change and Air Pollution on Health

Area of Science:

• Environmental Health
• Climate Science
• Public Health

Background:

• Air pollution causes millions of premature deaths and significant morbidity annually.
• Climate change can influence air pollutant dispersion and formation, potentially worsening health outcomes.
• Understanding these interactions is crucial for public health strategies.

Purpose of the Study:

• To review current evidence on climate change's effects on air pollution.
• To assess the subsequent impacts on human health.
• To identify research gaps in this field.

Main Methods:

• Literature review of recent studies.
• Analysis of modelled future air pollutant concentrations under various climate scenarios.
• Evaluation of projected health impacts, primarily mortality.

Main Results:

• Climate change is projected to increase mortality related to ozone and fine particulate matter in many regions.
• Impacts vary significantly based on climate scenarios, regional factors, and emission projections.
• Current research predominantly focuses on mortality, with limited data on morbidity.

Conclusions:

• Climate change poses a significant threat to air quality and related public health.
• Uncertainty remains high due to varying climate and emission scenarios.
• Future research should prioritize understanding the effects on morbidity and regional health disparities.
