The climate crisis has led to the fact that the flowering season of plants has become longer, and the effect of the pollen itself is more intense.

The study was conducted in North America, but its authors believe that this sad pattern for allergy sufferers and asthmatics is likely to be observed in other parts of the world.

Another example of the negative impact of global warming was discovered by American researchers, according to The Guardian: the climate crisis undermines the health of allergy sufferers and asthmatics. Research has shown that the pollen season now starts three weeks earlier, lasts 20 days longer and leads to a higher concentration of pollen in the air than it did at the end of the last century. Scientists came to such conclusions after analyzing data collected at 60 experimental stations in the USA and Canada. This is explained by the fact that, due to the increase in global temperatures, the flowering period of plants has noticeably lengthened. Winters are warmer now and springs come earlier.

According to the authors of the study, this is a prime example of the fact that climate change has already become a reality: it can be detected in every breath we take. The negative health effects are obvious and the situation will only get worse. According to the authors of the study, the pollen season is likely to become longer in other parts of the world. As the climate continues to change, the incidence of asthma and allergies caused by airborne allergens will increase in the future.

The tiny pollen grains that plants secrete to reproduce can cause seasonal allergies, such as sneezing, itching, red eyes, and a runny nose. The flowering season can also worsen other conditions such as asthma.

The research is published in the journal Proceedings of the National Academy of Sciences.
