An Arctic cold snap that began in 1998 could last for years, freezing the northern marine passage and making it impassable without icebreaking ships, said Oleg Pokrovsky of the Voeikov Main Geophysical Observatory.
"I think the development of the shelf will face large problems," Pokrovsky said Thursday at a seminar on research in the Polar regions.
Scientists who believe the climate is warming may have been misled by data from U.S. meteorological stations located in urban areas, where dense microclimates creates higher temperatures, RIA Novosti quoted Pokrovsky as saying.
"Politicians who placed their bets on global warming may lose the pot," Pokrovsky said.
