Absence A new study found that they are increasingly intense and durable due to climate change. According to researchers at the Faculty of Medical and Health Sciences at the University of George Washington, The length of heating Pollination seasons worldwide. The new work is based on previous studies associated with the worsening of allergies in Europe With climate change And high concentrations of CO₂ in the atmosphere.
Climate change brings pollen 19 days a year
The new research published in the ‘The Larinkoscope’ magazine examined the study between 2000 and 2023 To find associated datos Global warming with pollen production. Sixteen studies identified an increase in temperature and a connection between Prolongation of seasons Pole.
Our changing climate Plants cause to change the time of their growth levels, releasing a long time before and Microscopic particles It allows for reproduction.
Some investigations predict it Total pollination production In the United States, it is likely to increase to 40% by the end of the century. Allergic season is also expected to begin before, and in some places pollen, which will make the conditions of allergies worse.
Global warming brings new allergic plants to Europe
Previous investigations have been analyzed Change of output systems Pollen in Europe. A 2019 study found that the pollen season lasts an average of 0.9 days per annum in Europe. 2014 Investigation In urban areas where most Europeans live, he found, The hottest temperature increased For the effect of the urban heat island, they led to the earliest beginning of the pollen season.
Other studies have decided that An increase in the temperature CO₂’s atmospheric concentrations stimulate the growth of plants, which intensify pollen concentrations in the air. An increase in moisture and storms During the policy center, they may increase pollen concentrations and allergies in the air, which can cause very severe allergic reactions and asthma attacks.
Global warming It also helps to migrate new species of occupied plants to Europe. AmburziaFor example, He reached the continent Decades ago, seed was brought from North America with seed exports. The plant is very allergic and releases pollen at the end of the year, and in September, it may extend the allergy season.
Medical experts play an important role in climate crisis
The effects of climate change During the pollen season, allergic conditions increase even in the case of weak allergies first. According to the average circumstances of the emission Greenhouse gases According to a 2017 study published in some European countries by 2050, Ambusia Awareness is expected to increase by 200% from the Inter -Government Expert Panel on Climate Change (IPCC).
It is expected Those who are already sensitive Pollen experiences the most serious and prolonged allergic symptoms, which can worsen respiratory problems and increase the death of asthma patients.
Researchers at the University of George Washington Pressure on medical professionals To understand the impact of climate in allergic conditions to prepare patients to increase pollen levels, it is beneficial to the planet.
“Doctors are in a unique position In the event of allergic rhythm in the patient’s decisions, climate change can change their practice, ”said Alisha R. Pershad. As voices of confidence in society, they must take advantage of their first -line experience for a significant change Weather“.
