There are three harm effects caused by greenhouse gases
1. The Global ocean “turns acidâ€
2. Ozone “sieve”
3. The contribution of methane
The Global ocean “turns acid”
In Septembers edition of magazine “Nature “ researchers from Livermore national laboratories inform, that the Global ocean becomes more “acidic “. At opinion of authors of the publication, it is caused by growth of maintenance CO2 in an atmosphere. The matter is that CO2 greater part is absorbed at ocean where this gas turns to a carbon acid. This change is not so great yet, however, scientists consider if emissions will not be reduced, it will create serious threat of a life not only in the sea, but also on a planet as a whole. All sea organisms will suffer from increase of acidity in some dimension , but most of all - waters living at a surface, where these changes are expressed especially strongly. The risk for coral reeves and other organisms, whose skeletons or bowls contain a carbonate of calcium, is greatest.
Ozone “sieve”
In biological history of a planet it is possible to allocate two characteristic periods.
The first proceeded before nearby 3 billion years when all new organisms were continuously formed . Kinds, families and kin of organisms appeared and disappeared.
On the second - in duration of tens millions years - the structure of inhabitants of a planet in general was stabilized, and new organisms appeared seldom.
What has occurred? In opinion of some scientists, including managing professor on faculty of chemistry of Rybinsk technological academy of aviation, G.M. Kimstach , the reason can be hidden that on boundary of two epoch, the stabile structure of an atmosphere and that ozone cloud ( which is now exhausted ) ,was generated. The main chemical characteristic of ozone - high oxidizing ability, expressed in particular, in strong sterilizing action: in ozone expires not only bacteria, but also fungus, and viruses.
The ozone cloud could become powerful ” a sanitary barrier “, protected the community of alive organisms ,which have been generated on the Earth, from probable “newcomers”. But now, when the ozone cloud quickly turns to a “sieve†, there is much more serious threat on a planet - occurrence of new , and dangerous, organisms.
The contribution of methane
The doctor of geology -mineralogical sciences N.A. Jasamanov , assume, that in present global warming is ” blameworthy ” basically methane.
” Climatic active workers ” the hotbed effect and anthropogenic emissions CO2 in an atmosphere consider as synonyms. Meanwhile this gas does not rise in the top stratums of an atmosphere, and in bottom is successfully absorbed by vegetation and soil organisms, dissolved in the rivers, lakes and the seas. Most part of CO2 is spent for construction of a water organisms skeleton and acquired by phytoplankton, and surplus is accumulated in ground deposits. Methane from a terrestrial surface quickly gets on border of troposphere and a stratosphere. Besides that , it actively participates in a greenhouse effect, at height of 15-20 km , under action of solar beams it decays on hydrogen and carbon which, incorporating to oxygen, forms CO2.
Whence methane come in an atmosphere? It is formed in a marshland on decomposing organic chemistry processes . Not without reason it still named marsh gas It gets in an atmosphere and from tectonic breaks and cracks at earthquakes. Anthropogenic emissions of methane are also great. By the estimations, natural and anthropogenic emissions make approximately 70 and 30 %, but the last promptly grow. As a whole steady growth of the maintenance of the methane , in an impression, fixed last decades, forces to doubt that climatic changes are caused only by those anthropogenic factors which so ” enthusiasts of Kyoto ” like to discuss in more and more warm climate.
