Whether one chooses to believe that the present climate change is primarily due to human activity or that these changes represent another global cycle, as has occurred in the history of the earth, the evidence that warming is occurring is uncontroversial. As stated by Beggs, there is now a wealth of evidence that climate change has had and will have a further impact on a variety of allergenic plants. In the face of adequate moisture, increased carbon dioxide generally increases plant biomass and pollen production. It is conceivable that increases in airborne pollen numbers  will increase the efficiency of windborne pollination, thereby increasing propagation of such plants. The expectation then is that there will be increasing amounts of robust allergenic plants and an increasing aeroallergen burden for those with inhalant allergy. Ariano and coworkers showed an increase in sensitization for Parietaria, birch, cypress, and olive, which paralleled the increases in total pollen counts. Although purely speculative at this time, it is interesting to consider the role that climate change, with the concomitant increase in certain aeroallergen exposures, may have in the increased prevalence of atopic disorders. Although the additional role of air pollutants in augmenting allergen sensitization and their interaction with aspects of climate change is beyond the scope of this review, recent reviews have addressed this interplay. It is obvious that an assortment of research approaches can provide useful insights into the impact of climate change on aeroallergens and resultant allergic disease. Considering the cascading effects of increased carbon dioxide and temperature, increased biomass, increased pollen and aeroallergen burden, increased sensitization, and finally atopic illness, further research can be directed to all of these levels. Monitoring of changes in pollen counts and plant phenology continues as a useful gauge of climate change. Additional studies of airborne characterized allergen levels will give greater precision in assessing aeroallergen burden. Expanded studies of other relevant aeroallergenic plants besides Ambrosia and Artemisia should be an area of further research. The paucity of published studies of the impact of carbon dioxide and other environmental variables on airborne allergenic fungi reinforces the need for research in this arena.
