Permafrost thaw threatens Russia oil and gas complex: study

(AFP) MOSCOW — Thawing permafrost caused by global warming is costing Russian energy firms billions of dollars annually in damage control and shrinking Russia's territory, Greenpeace warned in a new study Friday.

According to the report by the environmental watchdog, up to 55 billion roubles (1.9 billion dollars) a year is spent on repairs to infrastructure and pipelines damaged by changes in the permafrost in western Siberia.


"For Russia, the biggest threat of the permafrost melt is to oil and gas company infrastructure," said Vladimir Chuprov, who heads Greenpeace's energy programme in Russia.

He said that the group had consulted with experts at gas giant Gazprom in writing its report, which detailed the destruction to infrastructure such as pipelines caused by rising temperatures and resulting melt water.
