How Climate Change Will Aggravate Your Allergy

If with each spring that passes you perceive that your seasonal allergy seems more intense and persistent, it is not something of your imagination. The main culprit of the phenomenon is climate change ... and every year will be worse.

During the spring month’s people suffering from allergy suffer from habitual symptoms such as sneezing, runny nose, itching, watery eyes or fatigue, often having to receive pharmacological treatment.

And with each year, the allergy is more incisive due to climate change. The reason? According to the Union of Concerned Scientist, carbon dioxide increases the growth rate of plants, which in turn increases the amount and potency of pollen, prolonging the allergy season and making it more intense. Higher temperatures can also lead individual plants to produce more pollen.

Increasing carbon emissions are causing the average surface temperature of our planet to increase. Last year was the fourth warmest year recorded, and the warmest recorded for the oceans. According to the Asthma and Allergy Foundation of America (AAFA), the highest temperatures extended to the USA. UU up to 27 days from 1995 to 2011.

On the other hand, a recent study published in The Lancet analyzed the duration of the pollen season and the amount of pollen per plant in 17 locations throughout the northern hemisphere. According to the data, which were collected during 26 years, 70% of the total volume of pollen has increased per season. In 65 percent of the spots, the pollen season has "increased in extreme temperatures," the authors reported.

Lewis Ziska, the lead author of this study, works with the United States Department of Agriculture. He told the Union of Concerned Scientists about another climate-related allergy problem: plants use carbon dioxide to produce food through photosynthesis, but the extra carbon dioxide in the air causes the weeds that propagate the pollen and cause allergies grow faster than "useful plants" like rice and wheat.

"Ambrosia, specifically, grew faster, flourished earlier and produced significantly greater pollen," Ziska said. This plant triggers what is known as hay fever.

If carbon dioxide emissions remain uncontrolled, the production of ragweed pollen could increase by 60 to 100 percent in the next 65 years. According to the AAFA, ragweed pollen could also become more allergenic as carbon dioxide levels increase. According to Annesi-Maesano, floods due to sea level can also cause another type of allergy due to the proliferation of mold, which can cause respiratory irritation and is a common trigger for asthma and allergies.

Children are more likely to suffer from these allergens, since their organs and immune systems are still forming due to their exposure to climate-related contaminants. In particular, children in low and middle income countries are disproportionately affected by the consequences of global warming. As carbon emissions increase, allergies will continue to get worse.
