Pollen "greener" skies over North Carolina

Do not configure the display settings. This supernatural green haze of the photo, covering the U.S. state of North Carolina, is the overabundance of pollen.

The news is not particularly pleasant for people with allergies. The increase in the concentration of pollen in Durham has led to the fact that the regional division of air quality announced a degree of "gravity" of pollen as "very high".

Photos of the affected areas show the trees and houses in a green haze from the abundance of pollen.

The main pollen comes from trees like pine, oak, mulberry, birch, beech, according to a group monitoring the pollen in North Carolina. In the American press, this phenomenon is described as "peloponnisos" and "the vision of hell for the sick hay fever".

It is believed that global temperature rise should be longer seasons of pollen which aggravated allergies in humans in recent years. According to the Agency for environmental protection, in the United States registered an increase in the number of days with high pollen levels, and in some areas since 1995 were observed in 25 additional days of suffering for people with allergies related to pollen.

The same thing happens all over the world. A study in the journal Lancet Planetary Health, showed that the amount of pollen in the air increases in most of the studied plots with increasing mean temperature.

Scientists estimate that in 2000 cubic meter had about 8,000 pollen grains. According to forecasts, in 2040 there will be about 20 000.
