United States: The period for allergies is approaching its peak. Recent research indicates that numerous Minnesotans experience nasal discharge and eye irritation before the traditional tree pollen season normally begins.
More about the news
A New Jersey-based nonprofit organization known as Climate Matters assessed historical federal weather records covering 186 US cities that included Minneapolis, St. Paul, Duluth, Rochester, and Mankato.
Minnesota regions experience the annual allergy season nearly a month longer on average than they did in the 1970s, according to results published earlier this month.
The time span of allergy season has nearly doubled in Minneapolis and St. Paul when comparing the present day to fifty years ago, resulting in an average of 27 extra days, as US News reported.
The annual allergy season in Duluth grew by 24 days, but Mankato increased by 11 days, and Rochester experienced 10 additional days.
Research conducted by scientists continues to confirm decades-long findings that human-induced climate change produces rising seasonal allergy problems for people worldwide.
What are the experts stating?
The expert allergy specialists indicate that the warmer temperatures trigger spring blooms to start their pollination season earlier while producing pollen for longer periods of time and creating allergenic-specific pollen grains.
Professor Andrew Rorie from the University of Nebraska explains that elevated air carbon dioxide levels are established facts as chairperson of the National Allergy Bureau, as US News reported.

Allergic reactions affect approximately one-quarter of all US adults and around twenty percent of children who are primarily sensitive to seasonal tree pollen in the spring and summer grass pollen and fall weed pollen.
Pollen grains entering the body attach to mucus membranes, which leads to nasal inflammation and eye irritation. Reactions of some patients extend to breathing difficulties.
