Global warming ends: in the years to come decrease of temperature on a global scale, although its nature and will be sparing. This forecast was made, scientists from the Physics Institute of the Russian Academy of Sciences (FIAN).
Moreover, according to research conducted by the staff Dolgoprudny Research Station of the Institute, together with colleagues from the Central Aerological Observatory of Roshydromet and Institute of Nuclear Physics, Moscow State University, the process of global cooling has already begun, ITAR-TASS reported.
After the peak in 2005, the year is the average temperature on Earth has decreased by 0.3 degrees, and returned to the level of 1996-1997-second period. By 2015, the year, the scientists believe, it will drop even a half tenths of a degree, which corresponds to the climate of the early 80's of the last century.
The year 2020 will force the inhabitants of northern latitudes to remember the harsh winters of 1978 and 1979's, and in 2040, the year the planet will "freeze." However, only a relatively high level in the temperature interval from 1880 to 2006-th year. Then we can expect a decrease of temperature of 0.5 degrees Celsius compared to the current figure of "global thermometer".
It became clear in the course of research, the cause of climate change is not related to the activities of the human civilization and is in space. The fact that the Earth's atmosphere constantly get cosmic dust particles. For a variety of observations, the number of drop-down dust varies from 400 to 1,000 tons per day.
The dust particles, in turn, are effective centers of condensation of water vapor. Thus, the more the Earth enters the dust, the greater the cloud cover of the planet, the more it reflects into space solar radiation flux. Consequently, the climate becomes colder. It turned out that periods of warming and cooling coincide with periods when our planet "envelop" in a particularly dense cloud of interplanetary "dirt."
"The main supplier of the dust — comets, — the party of work, Chief Scientific Officer of FIAN, Professor Yuri Stozhkov. — Approaching the Sun at a distance of less than two astronomical units, they cast off the frozen on them "coats" of dust and gas to form a gas tails. Then the dust enters the Earth's atmosphere, and eventually settles on the surface. "
Thus the amount of incoming cosmic dust to us must depend on the relative positions of the planets, said the scientist. "After all, depending on their location changes the trajectory of comets and their number in the space between the Sun and the orbit of Mars, where the zodiacal dust cloud. Based on these considerations, in the concentration of cosmic dust and, therefore, the earth's climate, the frequency should be similar to those observed in the position of the planets, "- said Stozhkov.
To test these assumptions, the researchers compared the periodicity in the arrangement of the planets and temporal periodicity of global climate change of the Earth. It turned out that the temperature data is a global network of weather stations and count scientists cosmic dust "traffic" are virtually identical. Discrepancies are up 1-3%. Using the obtained patterns, scientists predict climate change over the next half century.
The work done — not the first, which has announced the periodicity of climate change and, consequently, of incorrect predictions of global warming, experts FIAN. One evidence of the calculations of Russian scientists began a study of ice cores extracted from a well drilled above Lake Vostok, Antarctica.
The longest core length 3623 m allowed to conclude that the changes in temperature over the last 420,000 years. During this time in the world there were at least four significant temperature variations in a big way at 8 degrees! So the upcoming cold snap may be considered sparing. In any case, a century ago, the world was one degree colder than today. And for much of the global climate, say meteorologists.
