The Sneezing Season Are Getting Worse in the US

As someone who is prone to seasonal allergies, I found this recent article on Quartz both intriguing and beneficial.

According to the article, people are getting more seasonal allergies to pollen during the spring summer, especially in the United States. It’s widely believed that climate change is the driving force behind this trend. The article examines how pollen seasons are being extended over time due to earlier and prolonged springs, which are influenced by climate change.

A 2021 study highlighted in the article found that average pollen season in North America increased by 21% in total springtime pollen counts, between 1990 and 2018. Researchers estimated that climate change directly contributed to half of the extended spring days and 8% of the heightened pollen counts.

Our results reveal that anthropogenic climate change has already exacerbated pollen seasons in the past three decades with attendant deleterious effects on respiratory health.

Although the article acknowledges that not all allergy increases can be attributed solely to climate change, it emphasizes the expectation of worsened pollen allergies in the future, especially in the U.S. and Europe. A 2014 study suggests that increased carbon dioxide levels can also lead to elevated pollen production.

It is likely that climate change will have even more of an impact on pollen seasons and respiratory health in the near future.
