Our Planet Will Have Less Sunny Days


Meteorological data, recorded for a period of more than 3 decades, shows that air pollution not only has a bad influence on planet's climate, but that it also covers the blue sky. Because of the increased concentration of solid particles and of the liquid drops in the atmosphere, the number of sunny days since 1970's has been reduced in the whole world, the specialists of Maryland University (USA) report.

Aerosols, including ashes, dust and carbon dioxide, are formed as a result of fuel combustion, burning of the tropical forests and industrial processes. The solid particles are very dangerous for human health and nature's equilibrium. As a result, every day is a new step towards the "gloomy zone", when the insufficiency of the sunlight will be felt not only in the cold season, but also during summers.

It's the first time now that experts acquire long term prognosis of the weather changes, based on the information they already had about the aerosols that now are part of the oceans' composition. Carbon dioxide and other types of polluting gases are transparent and have no influence on sky's visibility. Even though the consequences of polluting gases on Earth's climate were firmly appointed, scientists could not understand completely the role of aerosols. Now the ecologists consider that, along with the increase of the aerosols' quantity in the atmosphere, sky will become darker and the number of the sunny days will decrease. This is because these substances block the penetration of the sunlight on Earth's surface.

The stable growth of the concentration of aerosols has been studied since 1973 in a lot of high-industrialized countries.
