Global Warming

Global warming is inevitable as a result of the previous pollution of an atmosphere caused by activity of the human. This is conclusion contained in the expert report on consequences of change of a climate, for life-support systems of people and natural bio-systems.

The document has been approved on the Friday night , on April 06, 2007 in Brussels by the Intergovernmental commission of experts on a climate change which structure includes representatives from more than hundred countries.

According to scientists, today speech was about necessity of struggle against pollution of an atmosphere, and also about protection of the human and natural bio-systems ,against climatic changes which are produced by global warming. Report is approved , after a uneasy procedure. According to local mass-media, the reason of a delay with promulgation of the report which discussion has begun on April, 2nd, became disagreements between scientists and the diplomats, arisen at the statement of the final text of the document which proceeded all last night. According to mass-media, diplomats wished to soften some conclusions of scientists containing in the report.

Scientists expected , that by the end of 21st century the temperature on the Earth can raise up to 1,8 - 4,0 degrees of Celsius in comparison with temperature level in1990. That will lead to thawing polar ices, mountain glaciers and a continental permafrost; the level of the World ocean will raise and the extreme hydro meteorological phenomena will become frequent.

Global warming can lead also to that one billion up to three billions person will start to suffer because of lack of drinking water. Because of a drought a problem with a feed can arise at 200-600 million inhabitants of a planet. The water level at oceans growing as a result of climatic changes, and that will lead to growth of quantity of flooding, first of all, in the countries of Asia. In zones of flooding will annually be approximately 5 million persons.

Besides this ,because of rise in temperature on 1,5 - 2,5 degrees of Celsius, 20 - 30 % of kinds of terrestrial flora and fauna will appear under threat from disappearance.

Experts approve also, that as a result of global warming ,the Alps will lose third of mounting skiing resorts, and the Mediterranean becomes a zone of tropics. For last century the temperature on the Earth has raised ,on the average ,on 0,74 degrees on Celsius.

Global warming caused five periods of mass extinction all live forms on the Earth

Whether mass extinction threatens all alive on a planet?

If to judge under clause of the professor of the Washington university of Peter Ward, a question is not so rhetorical. He considers, that the reason of disappearance of dinosaurs and many other living creatures is not at all falling of asteroids ,as approve many popular theories ,but the Earth mechanism.

The Earth has the ruthless mechanism in the arsenal, which leads to mass destruction of organisms.

As is known, the majority of forms of a life on a planet practically stopped the existence at least five times for the last of 500 million years.

251 million years ago ” Great extinction ” has carried off more than 90 percent of all inhabitants of the sea and 70 percent of a land, including plants.

Ward in detail explains, why the reason of these cataclysms could not be asteroids. And then puts forward the version which was a result of its long-term researches. Here its essence. Studying samples of breed of the various historical periods, the scientist has paid attention, that the mass destruction of organisms occurred on a background of sharp falling of the maintenance of oxygen both in an atmosphere, and at ocean

Ward has shown, that high concentration of carbonic gas confirms a role of global warming in those tragic events. Today this parameter three times is less, that was during the periods mass dying out of alive essences. But if concentration СО2 will grow the same rates as it occurs now, by the end of century it will reach critical feature. The history will repeat, and all alive will appear as a victim of the sixth cataclysm?

Global warming escalates to the point of sharp falling of the maintenance of oxygen. Sharp growth of temperature prevented to acquire to ocean oxygen, creating perfect conditions for duplication anaerobe (oxygen-free) bacteria. Those bacteria in huge quantities developed poisonous hydrogen sulfide which has caused mass destruction of ground and sea inhabitants.

Simultaneously was observed accumulation of huge quantity of carbon, that caused a greenhouse effect, and global warming.

There are some ideas to avoid catastrophe caused by global warming.

1. to make salty gases, by means of special devices, which will take sea water and transform it into the real clouds sated by sodium chloride.
2. creation of floating artificial small islands ,white colored, with a reflecting surface in sea zones
3. or to covering some desert areas with plastic materials (the same white color) for reflection of the solar radiation getting to the Earth
4. dispersion of substances above ocean, which will promote growth of the seaweed, for absorbing great volumes of carbonic gas ( that is already realized in some areas of Antarctica ).
5. to place ,around of the Earth, millions lenses in diameter of 60 cm and weight few grams, which will be capable to reflect solar beams
6. to create ,around of the Earth , a ring of fine particles or spacecrafts with which it is possible to shade tropics to soften a climate

Is this ideas enough to slow down global warming? Maybe the survival of mankind depends on his ability to find new houses in other place in the Universe, because the risk of destruction of alive essences as a result of global warming promptly increases? Maybe people have to build constant base on the Moon in 20 years and a colony on Mars the next four decades? Is there link ,missing in the logical chain of the scientific arguments?

Because of complexities of the analysis of global changes of temperature ,some scientists till now do not recognize warming by the fact ,and prefer to speak about global warming as about the plausible hypothesis requiring careful check.

Climatologists from the largest world research centers, having collected accessible archives of meteorology data from different corners of globe, have processed them and have led to a uniform scale.

On those archives are visible two distinct episodes of global warming.

1. for the period 1910 - 1940. For this time the average temperature on the Earth has grown on 0,3- 0,4°C. Then within 30 years the temperature did not grow and, probably, even has a little decreased.
2. And the new episode of warming which proceeds till now has begun in 1970’s . From this time the temperature has raised for 0,6- 0,8°C.
