Abstract: The influence of heightened doses of the active UVB radiation at the wavelength λ ≤ 310 nm upon surface and aquatic ecosystems is examined in the article. We show that the CO2 growth in the atmosphere in the1980-90s up to 1.6 million a year occurred under regular growth of the UVB radiation in this period as a result of the ozonosphere continuous volcanogenic depression because of abnormally high frequency of volcano eruptions, spreading their products in the stratosphere. Not only the photosynthetic activity depression in surface and aquatic ecosystems but also the decrease of the ocean absorption property as a result of the essential temperature increasing of its surface approximately by 0.7ºC in this period because of intensive absorption of the rising UVB radiation by dissolved organic substance preditermine the CO2 acceleration of growth.
