A growing amount of research demonstrates that large changes in the atmosphere and climate, notably anthropogenic-caused global warming, have an influence on the biosphere and human environment. Epidemiological and experimental investigations on the association between allergic respiratory illnesses, asthma, and environmental factors such as climatic variables, airborne allergens, and air pollution provide current understanding on the effects of climate change on respiratory allergy. The increased prevalence of respiratory allergy disorders and bronchial asthma in most industrialised countries has been connected to urbanisation, with its high levels of automobile emissions, and a westernised lifestyle. However, assessing the effects of climate change and air pollution on asthma prevalence in the general population and the timing of asthma exacerbations is difficult, despite the fact that the global rise in asthma prevalence and severity could also be attributed to air pollution and climate change. Because airborne allergens and pollutants are frequently increased in the atmosphere at the same time, an enhanced IgE-mediated response to aeroallergens and increased airway inflammation could explain the rise in the incidence of respiratory allergy and asthma in atopic people over the last five decades. The link between air pollution and respiratory allergic disorders including rhinitis and bronchial asthma is extensively studied using pollen allergy.
