In many parts of the American state of North Carolina, a mysterious greenish haze has recently appeared, for which, however, a rational explanation was quickly found. According to experts, the excess in the air of pollen flying from oaks, pines, birches, mulberries, beeches and other trees during spring flowering was the culprit. This news was especially unpleasant for local residents with allergies.
So, in the city of Durham, the concentration of pollen from flowering plants was so high that local experts declared it "dangerous" to life. Photos of the "affected" area are circulating on the World Wide Web, showing houses and trees in a surreal green haze, like something out of a science fiction movie. Naturally, many Internet users began to make the most frightening assumptions, but they were quickly sobered by scientists.
The researchers found that the abundance of pollen in the air was the result of rising temperatures due to global climate change. Since 1995, the number of days in the United States with allergy sufferers has increased by 25 overall, almost a month, according to US EPA data. The same thing, by the way, is happening in some other parts of the world, where the average annual temperature rises relentlessly.
