Continuous global warming, which has lately been the talk of the day, will not happen after all. In the 21st century, warming and cooling will be alternately replacing each other approximately every 40 years, with each subsequent cooling more severe than the previous one. This is proved by changes in the ice situation in the Arctic, Nikolay Dobretsov, Doctor of Geology and Mineralogy, the Chairman of the Earth Science United Academic Council, has told The Voice of Russia. He is convinced that the hypothesis of continuous climate warming on our planet has considerably exhausted itself.
“There were views that anthropogenic interference, like emissions of greenhouse gases by all heat electric power stations and all industrial influence in general, has resulted in irreversible changes in the Earth’s climate. Those views were based on excessively rapid warming in the 20th century which was thought to continue indefinitely. However, the events of the last three years, when Venetian canals froze and Spanish vineyards were destroyed by frost, and the fact that now Moscow and a considerable part of Europe are having a particularly long winter, prove that temporary cooling has begun. The same is happening to the Antarctic ice. The smallest ice volume and area in the Antarctic were observed in 2007 and 2008. In 2009, 2010, 2011 and early 2012, the volume of ice grew.”
Thus, the academician says, the theory of continuous warming is not getting practical proof. In this century, the volume of the Arctic ice will grow and contract by turns. On the other hand, no one can say when the planet is to expect a new Glacier Period, similar to the one contemporary Europe saw 20,000 years ago, Nikolay Dobretsov continues.
“The Arctic determines the weather on the planet, so we should build a network of stations there for a detailed study of this issue. After that we’ll be able to make a theoretically substantiated forecast.”
The scientist stresses that meteorological and other scientific stations in the Arctic should be equipped with super-modern equipment to raise the reliability of the forecasts. The construction of one of the first stations on Samoilovsky Island in the estuary of the Lena River in Siberia is already in full swing and will be completed in August this year.
Scientific discussions of global warming are many years old, even though geological research testifies that cooling always followed warming on Earth. Contemporary theories explaining the reasons for and consequences of global warming have once again been challenged by the latest American investigation which has proved that Earth warmed and cooled off in the Middle Ages as well. A team of scientists from Syracuse University in New York State has discovered that in the Middle Ages warming happened not only in Europe but also in the Antarctic. This means that Earth has already experienced global warming, even without human influence and emissions of carbon dioxide. The results of the investigation will be published by The Earth and Planetary Science Letters on the 1st of April.
