Global Climate Change and Pollen Aeroallergens: A Southern Hemisphere Perspective

Janet M Davies et al. Immunol Allergy Clin North Am. 2021 Feb.

Abstract

Climatic change will have an impact on production and release of pollen, with consequences for the duration and magnitude of aeroallergen seasonal exposure and allergic diseases. Evaluations of pollen aerobiology in the southern hemisphere have been limited by resourcing and the density of monitoring sites. This review emphasizes inconsistencies in pollen monitoring methods and metrics used globally. Research should consider unique southern hemisphere biodiversity, climate, plant distributions, standardization of pollen aerobiology, automation, and environmental integration. For both hemispheres, there is a clear need for better understanding of likely influences of climate change and comprehending their impact on pollen-related health outcomes.

Keywords: Aeroallergens; Biodiversity; Carbon dioxide; Climate change.
