MOSCOW, February 6. /TASS/. There is been no global warming over the past fourteen years but scientists are divided in their assessments of the impact of human activity on the condition of climate, Dr. Robert Nigmatulin, the director of the Institute of Oceanic Studies reporting to the Russian Academy of Sciences said on Thursday.
"Manmade concentration of carbon dioxide is really growing," he said adding that this gas did contribute to the greenhouse effect, although it was increasing the atmospheric temperatures but insignificantly.
However, these slightly heightened concentrations intensified evaporation of water from the surface of the world ocean and the increase of concentration of aqueous vapor, which was producing a strong greenhouse effect.
"In the meantime, there has been no greenhouse effect over the past fourteen years," Dr. Nigmatulin said. "One of the explanations is the rising concentrations of aqueous vapor naturally bring about a thickening of the cloud cover, which in its turn increases reflection of solar light by the atmosphere."
"Quite possibly, a mechanism of this kind is in action now," he said. "I’m scrutinizing it now but I can’t give you more precise information yet."
"On the whole, the research community is split into two camps now, one saying that man is to blame for the global warming and the other insisting that, no, the anthropogenic factor does not play a decisive role in climate warming," Dr. Nigmatulin said.
