Infinite allergy season
The Department of Climate and Space Sciences and Engineering from the University of Michigan, working on a which predicts the intensity and From 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 Plants are responsible for 77% of respiratory allergies in the country. According to their results, the From They may be much longer, but they are also much more severe than the ones we are currently facing. Bad news for allergy sufferers!
Simulations indicate that spring pollen can appear 10-40 days in advance, and those of summer andLasts up to 15 additional days. Regarding the intensity of pollen emissions, all species Analyzed here does not react the same way. For example, file 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. The scientific community has made it for many years. when 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.
