From the Heartland Institute
By Anthony Watts and Sterling Burnett
Axios Atlanta recently published an article entitled “Pollen season in Atlanta becomes worse thanks to climate change” and claims that rising temperatures caused by climate change make the allergy season more serious. Axios' article is at best misleading and misses a larger point. Data and historical trends indicate that the pollen fluctuations fluctuate, factors such as changes and changes in land use-especially the EHI effect of Urban Heat Island (UHI) are more important to the pollen patterns of Atlanta as their so-called local climate change.
“A warming climate means that the allergy time lasts earlier and longer,” write Kristal Dixon and Alex Fitzpatrick for Axios. “Longer, warmer growth seasons lead to previous pollen releases and higher pollen mirrors.”
Dixon and Fitzpatrick ignore several important facts when trying to combine long -term climate change with longer allergy times. For example, the well-documented urban heat island effect from Atlanta, which is determined by dense infrastructure, concrete and asphalt-catching thermal shops, plays a much greater role in local temperature trends than any influence of global warming. The city has been significantly expanded in recent decades, increased the localized temperatures and the expansion of the vegetation period for plants.
According to a NASA analysis of the Uhi effect of Atlanta, the city experiences significantly higher temperatures than the surrounding rural areas due to people who keep warmth. This localized warming-not the global climate change activity an essential driver for temperature-related shifts of the pollen cycles.

Second, pollen mirrors are strongly influenced by regional vegetation patterns and CO₂ adhesive effects that lead to healthier plant growth.
As can be seen in an article about climate level, the pollen season largely depends on the rainfall levels and the natural climate variaability, not just on the temperature. If there are more rain, plants produce more pollen. Conversely, droughts can suppress pollen mirrors. Climate models do not take into account these local and regional factors reliably, but Axios presents the problem as if they were only driven to global temperature changes.
In addition, earlier claims on the deterioration of the allergy seasons have not decided to test. For example, an analysis of climate event in 2022 exposed similar claims by showing that pollen trends vary according to region and that some areas actually have fewer pollen. In addition, studies that are cited in the mainstream media are often based on cherry-accused data from limited time frames instead of examining long-term historical trends.
Axios accepted the use of “consecutive freezer -free days” by climate Central as a deputy for the pollen season and found that between 1970 and 2024 the number of consecutive freezer days such as Reno, Myrtle Beach and Toledo was increased. Interestingly, it did not provide any data that took into account the treatment of allergies or the sales of allergic medicine in these cities, which corresponds to the increase in days between and without freezing temperatures. And although climate change was an allegedly global phenomenon, it turned out that the number of cities recorded a decline in the number of successive freezing days. If Axios asked these questions, there was certainly no response to them in the article, but this is a reasonable connection if you ask whether climate change affects allergies.
Even if climate change, in contrast to other factors, causes longer allergy times, this misses a larger point, the positive advantages of decline in freezer temperatures. The Axios story mentioned one in passing, but could not expand the letter. “[a]Bove-Freezing temperatures enable better plant growth. “While the suffering of allergy sufferers should not be ignored, as Axios determines, allergies are treatable, but less to the freezing days and nights are to benefit plants, insects and humans alike.
Climateism has made this point in repeated articles here, here and here, for example. Global Greening has contributed to the greatest decline in global hunger in history. Higher plant growth not only removes carbon dioxide from the atmosphere, but the allergy causes pollen that emits it is ideal for pollination of insects such as bees and birds.
Extensive, checked plenty of reports, which checked, confirm that the cold temperatures are responsible for ten times more deaths than hot temperatures. As a result, the number of deaths that are due to non-optimum temperatures also fell very much, since the number of freezes has decreased, which prevents hundreds of thousands of deaths every year.

Instead of pursuing a wide, evidence -based approach, Axios has again attempted alarmist claims without removing all relevant factors. The allergy season in Atlanta is influenced by many variables, including changes in land use, dense urban landscape design with pollen production facilities, increased green areas and urbanization. The guilt of climate change without taking these other influences is misleading and promotes unnecessary panic. If the media are really interested in informing the public, you should concentrate on all contributors that may cause a longer allergy season. You could also discuss the enormous global net locations of fewer freezers.
