The sharp warming which has begun in the second half of the century of a climate is an established fact. We feel it on softer, than earlier, to winters. The average temperature of a ground layer of air in comparison with 1956-1957 years when the First international geophysical year was spent, has increased on 0,7 degrees. On equator of warming is not present, but the more close to poles, the it is more appreciable. Behind Polar circle it reaches 2 degrees. On the North Pole subglacial water has become warmer on 1 degree and an ice cover has started to melt from below.

In what the reason of this phenomenon? One scientists consider, that it is result of burning of huge weight of organic fuel and allocation in atmosphere of considerable quantities of carbonic gas which is hotbed, that is complicates return of heat from a surface of the Earth.
What is the hothouse effect? Billions tons of carbonic gas hourly arrive in atmosphere as a result of burning of coal and oil, natural gas and fire wood, millions tons of methane rise in atmosphere from gas workings out, from rice fields of Asia, are thrown out there water steam.

All it - "hotbed gases". As in a hotbed a glass roof and walls pass solar radiation, but do not allow to leave to heat, and carbonic gas and others "hotbed gases" are practically transparent for solar beams, but detain long-wave thermal radiation of the Earth, do not allow to it to leave in space.
"The power boom" has increased leaving century concentration СО2 in atmosphere on 25 % and methane by 100 %. For this time for the Earth there was a real warming. The majority of scientists considers it as a "hotbed effect" consequence.
Other scientists, referring to climate change during historical time, consider the anthropogenous factor of warming of a climate insignificant and connect this phenomenon with strengthening of solar activity.
The forecast for the future (2030 - 2050) assumes possible rise in temperature on 1,5 - 4,5 degrees. To such conclusions the International conference on climatology in Austria in 1988 has come.
In connection with climate warming there is a number of accompanying questions.

What prospects of its further development? How warming will affect increase in evaporation from a surface of the World ocean and how it will be reflected in quantity of precipitations? How these precipitations will be distributed on the area? On all these questions it is possible to give the exact answer. Various scientific researches however should be for this purpose carried out.
