As fossil fuel combustion continues to power the global economy, the rate of climate change is accelerating, causing severe respiratory health impacts and large disparities in the degree of human suffering. Hotter and drier climates lead to longer and more severe wildland fire seasons, impairing air quality around the globe. Hotter temperatures lead to higher levels of ozone, and particles, causing the exacerbation of chronic respiratory diseases and premature mortality. Longer pollen seasons and higher pollen levels provoke allergic airway diseases. In arid regions, accelerated land degradation and desertification are promoting dust pollution and impairing food production and nutritional content that are essential to respiratory health. Extreme weather events and flooding impede healthcare delivery and can lead to poor indoor air quality due to mold overgrowth. Climate and human activities that harm the environment and ecosystem may also affect the emergence and spread of viral infections including Severe Acute Respiratory Syndrome-related Coronavirus 2 (SARS-CoV-2) and associated morbidity and mortality exacerbated by air pollution. Children and elderly are more susceptible to the adverse health effects of climate change. Geographical and socioeconomic circumstances along with a decreased capacity to adapt, collectively enhance the vulnerability to adverse effects of climate change. Successful mitigation of anthropogenic climate change is dependent on the commitment of energy-intensive nations to manage greenhouse gas emissions, as well as, societal support and response to aggravating factors. This review focuses on the respiratory health impacts of global climate change, with an emphasis on susceptible and vulnerable populations and low- and middle- income countries.
