Global warming in the next 40 years will allow Russian authorities to save on central heating, increase agricultural production and extend sea navigation in the north, a leading Russian climatologist told a Russian-German conference Wednesday.

- The reduction of heating alone outweighs all the negative results [of the global warming] by many times, said Vladimir Klimenko, head of Laboratory of Global Power Engineering Problems at the Moscow Power Engineering Institute, according to The Moscow Times.

Klimenko said the heating season in central Russia will be two weeks shorter by 2050, which will allow Russian authorities to reduce energy consumption by 3 billion tons of oil by that time. The season will shorten further by 2150, which will save 17 billion tons of oil by then.

In agriculture, the duration of the growing season will increase and the land area potentially suitable for agricultural use will increase by 33 million hectares by 2050 and 46 million hectares by 2150.

The duration of ice cover along the Arctic shoreline will decrease, resulting in a longer navigation of 50 days by 2050 and 105 days by 2100.

Also, by the end of the century, the Barents and Pechora seas will be ice-free the whole year round and summer transpolar voyage will become possible.

The average yearly temperature as a result of the global warming will rise in Russia by 2.5 degrees Celsius by 2050 and by 5 degrees by 2150, compared with the global rise by 1 and 2 degrees by respective years, Klimenko said.
