August 7, 2013. According to Australian biologists, the melting of ice in Antarctica leads to the fact that the surface of the ocean floor becomes more exposed to the sun. As a result, underwater polar ecosystems may be "absorbed" algae.
Animals that live in the waters of the Arctic and Antarctic, most of their lives in the dark. Sea ice prevents the penetration of sunlight into the water in the spring and early summer, and in winter the sun and all completely disappears behind the horizon. Thus, the only time when these creatures can see the sunlight - late summer and early autumn, the TV channel Read more [...]
16/12/2012 Due to global warming and melting ice in the Arctic and Antarctic scientists propose to resolve this issue once and for all. They offer frozen Arctic, which, however, will bypass the huge costs. This idea looks fantastic, but the environmental situation is on the brink of disaster. In the Arctic Ocean, the amount of ice mass in September fell to historically low levels. And now the sea-ice cover is only 50% of the area, which was recorded in 80 years. You can saturate the atmosphere with reflective particles, which reduces the penetration of sunlight at the North Pole. This should Read more [...]
University of Michigan scientists have found that the carbon in the permafrost in the Arctic is extremely sensitive to sunlight. When sunlight on the surface of the frozen ground last very quickly begin to emit the gas carbon dioxide (CO?), Which, in turn, actively contributes to global warming.In the study of the Arctic regions of Alaska, in which there is permafrost melting, seriously affecting the topography of the ice cover, it was observed that sunlight stimulates the bacteria to the active processing of carbon contained in the soil. Being processed up to 40% of the total carbon storage Read more [...]
March 1, 2013. Winter in Germany this year has been especially difficult. It's not the cold or the wind.
Climate change though, but man is not affected as much as the unusually small number of Sunny days.
All life on earth depends on solar energy. This winter, the Germans lost her more than ever. Most from gloomy days and pulled the heavy clouds of heaven suffers psyche.According to the results of meteorological research, German past winter was the most dark for the past forty-three years. During the winter months the sun is peeking just one hundred hours, which is sixty hours less than the Read more [...]
Anthocyanins, as already mentioned, give flowers of pink, crimson, red, violet, blue. Chalcones, Auron, some flavonols differ yellow color, and flavonol glycosides, along with anthocyanins give the color of flowers blue. Flavones found in the flowers of white and ivory colors. Bright and varied color of flowers in combination with drops of nectar attracts insects that are on their feet and abdomen carry pollen from flower to flower and thus contribute to pollination. In this delicate and perfect the mechanism of coloring flowers is an important and necessary part.
However, some observations Read more [...]
Heliotherapy - Treatment and hardening of sunlight - the active form of climatotherapy. She is in the process of walking, especially in spring and summer at a variety of ordinary activities of children in the air. For children of the sun is placed in direct sunlight, containing heat and ultraviolet rays. At this time, influenced by other meteorological factors (temperature, humidity, air velocity). This is evidenced by the radiation-equivalent-effective temperature (REET). Sunbathing appointed after the preliminary 3.5 air baths. Dosed depending on the state of children in biodozy largest Read more [...]
