endless allergy season

Yingxao Zhang and Allison SteinerFrom Department of Climate and Space Science and Engineering from the University of Michigan, working on a computer simulation which predicts intensity and Duration From emissions Daily pollen between 2081 and 2100 – in a world where temperatures would rise by 4 to 6 °C. His analysis is only for the United States and 13 . is related to taxa of plants accounted for 77% Allergies Respiratory system in the country. According to their results, Season From pollen May be longer, but may be even more intense than what we are currently experiencing. Bad news for allergy sufferers!

Simulations indicate that spring pollen may appear 10 to 40 days earlier, and summer pollen andDrop Will last for 15 additional days. With respect to the intensity of pollen excretion, all species Botanicals Analyzed here, do not react in the same way. for example, precipitation And temperature decreases daily pollen production by 33% for alder, but increases by 50% for oak.

Nevertheless, the overall increase in pollen emissions in a year ranges from 16 to 40%. more CO. Who says2 Atmospheric, also called excess pollen. it’s a vision Created by the scientific community for many years. when CO concentration2 Enter the researchers’ simulation, the peak in pollen production in recent years is still 2000% higher than that seen in the United States.

an important public health topic

Respiratory allergies due to pollen are a real public health problem. They are related to 20 to 25% of French people, adults and children alike. In sensitive people, respiratory allergies, such as tobacco or pollution, may promote the presence of asthma, This chronic disease is characterized bySwelling From bronchi that causes episodes of shortness of breath, shortness of breathOf Pressure Chest and cough.
