Permafrost thaw threatens Russia oil and gas complex: study http://apocadocs.com/s.pl?1258815788
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.... Russia's main raw export industries are spread across the Siberian permafrost, which makes up over 60 percent of its territory and includes 20 cities and several hundred thousand people.
The permafrost thaw has accelerated in recent years.... In a complex cycle, permafrost melts at the edges of lakes that previously were iced over year-round, he explained.
Organic material -- the remains of rotted plants and long-dead animals -- then melt into the lake from the soil and decompose to form methane. With the thaw, the methane bubbles to the surface and is released into the atmosphere.

It's so sad when nomenclature leads to a death spiral. Tempofrost would have changed everything.
