Due to global climate change, climatologists anticipate not only a rise in mean yearly ambient temperature, but also an increase in the frequency and intensity of variable weather patterns, including extreme hot and cold weather events [1, 2]. Overall mortality is higher during winter months [3, 4] and half of excessive deaths in the cold season are respiratory in nature [5]. Chronic obstructive pulmonary disease (COPD) is the third leading cause of death worldwide and is linked to high healthcare-associated financial burden [6, 7]. Identifying environmental factors that contribute to COPD morbidity is crucial to define adaptive strategies to improve outcomes.
