Russian Scientists report another cosmic origination for cloud condensation nuclei: modulated by planetary motion
Submitted on 2012/05/22 at 9:19 amInteresting article on a Russian paper here “Global warming is over, Russian scientists believe.”
“Thus the number of incoming cosmic dust to us must depend on the relative positions of the planets, explained 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, a change in the concentration of cosmic dust and, therefore, the Earth’s climate must be periodic, similar to those observed in the arrangement of the planets, “- said Stozhkov.”

Global warming ends: in the years to come the temperature drop across the planet, although its nature and will be sparing. So the forecast today with a shared corr. Tass, scientists from the Physics Institute of Russian Academy of Sciences / LPI /.
Moreover, according to research conducted by employees of Dolgoprudny Research Station of the Institute together with colleagues from Central and Upper-Air Observatory Hydromet Institute of Nuclear Physics, Moscow State University, the process of global cooling has begun. After a peak in 2005, the year is now the average temperature on Earth has decreased by 0.3 degrees and returned to the level of 1996-1997-second period. By the year 2015, scientists believe, it will fall a further one and a half tenths of a degree, which corresponds to the climate of the early 80-ies. The year 2020 has already make the inhabitants of northern latitudes to remember the harsh winters of 1978 and 1979, years, and in 2040 th year of the planet will begin to “freeze.” However, only a relatively high temperature mark for the period from 1880 to 2006-th year. Then we can expect a decrease of temperature of 0.5 degrees Celsius compared with the current measure of “global thermometer”.
As it turned out during the research, the cause of climate change is not related to the activities of human civilization in general is … space. The fact that the Earth’s atmosphere is constantly get cosmic dust particles, the scientists explained. According to various observations, the amount of precipitated dust varies from 400 to 1000 tons per day.
In turn, the dust particles are effective condensation nuclei of water vapor. Thus, the more dust enters the earth, the greater the cloud cover of the planet, the more it reflects into space flux of solar radiation. Consequently, the climate becomes colder. It turned out that the warming and cooling periods coincide with periods when our planet is “rolled up” in a particularly dense cloud of interplanetary “dirt.”
“The main supplier of this dust – comets – told of the party, Chief Scientific Officer Lebedev Physical Institute, Doctor of Physical Mathematical Sciences Yuriy Stozhkov. – When approaching the Sun at a distance of less than two astronomical units, they shed themselves of the frozen them “coats” of gas and dust and gas form the tails. Then the dust enters the earth’s atmosphere, and eventually settles on the surface. “
Thus the number of incoming cosmic dust to us must depend on the relative positions of the planets, explained 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, a change in the concentration of cosmic dust and, therefore, the Earth’s climate must be periodic, similar to those observed in the arrangement of the planets, “- said Stozhkov.
To test these assumptions, the researchers compared the frequency of pairs of planets in the location and temporal periodicity of the Earth’s global climate change. It turned out that the global temperature data network of meteorological stations and a calculated cosmic dust scientists “traffic” is practically the same. The discrepancy is at most 1-3 per cent. Using the obtained regularities, scientists have made predictions of climate change over the next half century.
Work undertaken – not the first, claiming the periodicity of climate change and, accordingly, the incorrect predictions of global warming, experts say FIAN. One of the confirmations of the calculations of Russian scientists began a study of ice cores extracted from boreholes drilled above Lake Vostok in Antarctica. The longest core length of 3623 m allowed to conclude that changes in temperature over 420,000 years. During this time the Earth was at least four major temperature fluctuations in a big way at 8 degrees! So the upcoming cold spell can be considered gentle. In any case, a century ago, the planet was one degree colder than today. And for a lot of global climate change, say meteorologists.
