This year, the heat, which appeared early in the season, contributed to the spread of a very large amount of grass pollen. According to the latest bulletin from the National Aerobic Bio-monitoring Network (RNSA), which monitors the content of biological particles in the air, the whole of France is still on a red alert for allergy risks.

Blame it on global warming

If it is big Allergy Should it subside after the end of June, we can expect longer and possibly more severe allergy seasons in the coming years.

because of, Global Warming. ” In 30 years, it has already been observed that the quantities of birch pollen have increased by more than 20% “Agency spokesman Samuel Monnier told AFP. As temperatures rise at the surface of the globe, some plants or trees also gain new territories. ” More and more ambrosia, highly sensitive plants, are moving north, including at altitudes Monnier notes.

In France, approximately 20% of children aged 9 and 30% of adults are now allergic to pollen, according to the Ministry of Health. Numbers that will inevitably increase in the coming years, specialists warn. ” Global warming will lengthen pollen seasons, while pollution will make pollen more aggressive.”warns Isabel Boss, president of the Allergy Guild.

Scientists have bad news for allergy sufferers

Article from Julie KernPosted on March 26, 2022

If you live on the Mediterranean arc, you may have an itchy nose, eyes Runny and uncontrollable sneezing for a few days. In the region, cupressaceae (redwood, cypress and junipers) emerge from their winter rest and produce pollen in large quantities. In western France, ash pollen saturates the air. 2022 season It started very early, from mid-January, particularly due to the mild temperatures recorded at the beginning of the year. A trend that is likely to continue, or even increase, with global warming.

Infinite allergy season

Yingsao Chang and Alison SteinerThe Department of Climate and Space Sciences and Engineering from the University of Michigan, working on a computer simulation which predicts the intensity and Duration subordinate emissions Daily pollen between 2081 and 2100 – in a world where temperatures jumped 4-6 degrees Celsius. Their analysis relates only to the United States and 13 classifications, from species to domain
There are many taxonomic ranks, from the broadest to… wiki-cc-30.jpg “data-url=”https://news.google.com/planete/definitions/classification-vivant-taxon-264/” data- more = “read more”>Categories Plants are responsible for 77% of respiratory allergies in the country. According to their findings, the pollen season could be much longer, but also more intense than the one we are currently experiencing. Bad news for allergy sufferers!

Simulations indicate that spring pollen can appear 10-40 days in advance, and those of summer andFall Lasts up to 15 additional days. Regarding the intensity of pollen emissions, all species plants Analyzed here does not react the same way. For example, file fall Temperature reduces daily pollen production by 33% for alder, but increases oak production by 50%.

However, the overall increase in pollen emissions over one year is 16-40%. Who says more CO2 Atmosphere, says more pollen. It’s a vision The scientific community has made it for many years. When carbon dioxide concentrations2 After entering the researchers’ simulation, the peak in pollen production is 200% higher than that observed in recent years, and still is in the United States.

An important issue for public health

Respiratory allergies to pollen are a real public health problem. It concerns 20 to 25% of the French, adults and children alike. In susceptible people, respiratory allergies, such as tobacco or pollution, can promote the onset of asthma. This disease is characterized by chronicignition bronchial function
The bronchi are involved in the passage of air (inspired or expired) between the outside and the inside of the lungs. It branches from the trachea into several bronchi and bronchioles (with the largest diameter … “data-image =” https://cdn.futura-sciences.com/buildsv6/images/midoriginal/c/a/5 / ca5f584969_50035683_bronche-gsk.jpg ” data-url =” https://news.google.com/health/definitions/biology-bronche-7300/ “data-more=”read more”>two branches Which causes episodes of shortness of breath and shortness of breath. the pressure chest and cough;

Approximately 2,000 people die each year as a result of asthma, including 100 children, teenagers or young adults. The French public health authority estimates that more than 60,000 people have been hospitalized asthma attack every year. In the coming years, respiratory sensitivity is likely to last longer and be more severe, increasing the risk of complications.
