Climate change and respiratory diseases: a 2020 perspective

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.
