The implications of climate change on respiratory allergies are yet unknown, and there are few studies on the subject. On the one hand, global warming is projected to impact the start, duration, and intensity of pollen season, as well as the rate of asthma exacerbations caused by respiratory infections and/or cold air inhalation. Spring events advanced by 6 days, according to data collected over 30 years by the International Phenological Gardens Network, with the highest rate of phenological changes reported in Western Europe and the Baltic areas. Pollen seasons are more frequently disrupted by poor weather conditions in late winter/ early spring due to their earlier commencement. The pollen season lasts longer, especially in the summer and with late flowering species. Plant and fungal reproductive systems will be affected by climate change in the next century, as will the timing, production, and dispersion of aeroallergens. Increased allergen exposure as a result of global warming, along with pollution exposure that acts synergistically to amplify the allergic reaction, could lead to an increase in respiratory difficulties in the future. In reality, climate change is anticipated to affect vegetation, resulting in changes in growth and reproductive cycles, as well as pollen output (seasonal period and intensity).
