Climate warming causes more snow in Siberia

"There is a paradox — a warming, which is characteristic of the world becomes more snow. This is in large areas of Siberia, where the snow more than it was one or two decades ago," — said the director of the Institute of Geography, Russian Academy of Sciences Vladimir Kotlyakov.
Global climate change leads to the growth of the snow cover in the Northern Hemisphere and in Siberia, said on Thursday the director of the Institute of Geography RAS Vladimir Kotlyakov, speaking at the World Forum of snow.

"There is a paradox — a warming, which is characteristic of the world becomes more snow. This is in large areas of Siberia, where the snow more than it was one or two decades ago," — said the honorary president of the Russian Geographical Society Kotlyakov.

According to geographer trend expansion area of snow in the northern hemisphere, scientists observe from the 1960's, when satellite observations began the spread of the snow cover.

"Right now, the era of global warming, with an increase in air temperature increases and moisture content of air masses, so in colder areas increased snowfall. This demonstrates the high sensitivity of snow cover for any changes in atmospheric composition and circulation, and this must be borne in mind when assess any human impact on the environment ", — explained the scientist.

In general, in the Northern Hemisphere snow much more than in the South, where it prevents the spread of the ocean. In February the snow covered 19% of the area of the world, with 31% of the Northern Hemisphere and 7.5% of the area of the Southern Hemisphere.

"In August, snow covers only 9% of the entire globe. In the Northern Hemisphere snow cover for the year varies by more than seven times, and in the South — less than half" — added Kotlyakov.

According to the National Oceanic and Atmospheric Administration (NOAA) USA, in December 2012, the total area of snow cover in the Northern Hemisphere was the largest in more than 130 years of observation — it almost 3 million square kilometers and has exceeded the average of 200 thousand square kilometers exceeded the record of 1985. On average, according to the American meteorologist, the area of snow cover in the Northern Hemisphere winter, grew at a rate of about 0.1% per decade.
