Investigators have determined that the leakage of of 20,000 tons of diesel (about 150,000 barrels) from a reservoir at a power plant in Russia’s Far North was caused by damage from thawing permafrost — just the latest sign of the catastrophic effects climate change is having in the Arctic.
"Entire cities and roads were built on permafrost,” said Guido Grosse, head of the permafrost research unit at the Alfred Wegener Institute in Potsdam, Germany. "When permafrost thaws, the ice deep in the ground that has been there for thousands of years melts, and you lose stability. That has an impact on infrastructure.”
Infrastructure in Siberia, northern Canada and Alaska is usually built on pillars that stand on top of the permafrost. With temperatures rising at twice the global average rate in the Arctic Circle, the frozen ground is thawing and causing cracks in roads and buildings.
