He told the doctor of geographical sciences Aleksey Galanin, chief researcher of the Institute of Permafrost. PI Melnikova SB RAS. "In total since 1957 - from about the beginning of global warming - the height of mountain glaciers Yakutia decreased by 70 percent, and their area has decreased by almost 40 percent. Over the past 10 years the rate of glacial melting is accelerating - two meters per year ", - said the scientist. According to him, on the surface it was the most ancient layers, whose age reaches two thoUSAnd years. The reverse process - the growth of glaciers - not happening. One of the possible consequences of this situation can be a serious increase in the volume of water in the northern rivers of Yakutia. According to the doctor of geological-mineralogical sciences, a member of the Academy of Sciences of the Republic of Sakha Viktor Shepelev, climate change are cyclical. "As a result of the many observations we can say that global warming, which is currently observed around the world, will last up to 2017-2020 years, and then to the years 2050-2060 will come again during the cooling," - he said. According to NASA in January, global warming has already led to an increase in the average temperature of the Earth's surface by 0.8 degrees since 1880 (the beginning of systematic observations). In the last year it was 0.69 degrees Celsius higher than the average of the XX century. On the causes of the global warming debate continues, some scientists believe that the role played by anthropogenic factor, an increase in the concentration of greenhouse gases emitted by different companies. Opponents of this hypothesis believe that the climate is changing cyclically the greatest influence on the average temperature of the Earth has a change in the energy flux from the Sun.
