Allergy nightmare. The longest dust for plants due to climate change

Researchers at the University of Michigan studied the relationship between height as a result Climate change Temperature and intensity Allergy People feel it. Their evolution indicates that the seasons Allergy They will get worse.

Researchers have developed a predictive model for the 15 most common types vaccine And study how its production is affected by expected changes in temperature and precipitation. They combined climate data with scenarios Social and EconomicThen they used their model to make predictions pollen emissions During the last two decades of the twenty-first century.

Based on the results of their calculations, scientists estimate that at the end of this century, spring pollen emissions may begin up to 40 days before 1995-2014. Allergy season may also last 19 days longer than it does today.

increase temperature And the ever-increasing focus Carbon Dioxide at Atmosphere Not only will they freshen the plants early, but they can also make them produce a lot of pollen that causes allergies. Its concentration in air may increase by up to 200%.

“Respiratory sensitivity associated with pollen increases with climate change,” says Yingxiao Zhang, author of a study published in the journal. Nature Communications. Our findings could be the starting point for further research into the effects of climate change on pollen and its health implications.

Allergy It can appear relatively mild, for example in watery eyes, sneezing, or rashes, but it can sometimes cause serious health problems, including difficulty breathing. According to the Asthma and Allergy Foundation of AmericaToday, 30% of adults and 40% of children in the United States have allergies.

The model developed at the University of Michigan may in the future enable more accurate prediction of allergy seasons in specific geographic areas.

“We hope to integrate our pollen emissions model into our air quality forecasting system to provide better climate-adapted forecasts,” said Alison Steiner, a climate scientist at the University of Michigan.
