Purpose of review: To present an overview of the impact of climate change upon human respiratory health.
Recent findings: Climate change involves two major types of change. First, there is overall progressive warming. Second, there is increased variability/unpredictability in weather patterns. Both types of change impact negatively upon human respiratory health. Worsening air quality and increased allergens can worsen existing disease. Climate-related changes in allergens and in vectors for infection can cause new disease. Redundant sophisticated studies have projected marked increases in respiratory morbidity and mortality throughout the world as a direct result of climate change. This article summarizes some of those studies.
Summary: The clarity of our vision with respect to the dramatic impact of climate change upon human respiratory health approaches 20/20. The data represent a mandate for change. Change needs to include international, national, and individual efforts.
