Arctic Cities Crumble As Permafrost Melts

One corner of a five-story building at 59 Talnakhskaya Street in the northern Russian city of Norilsk was sinking as the permafrost underneath it thawed and the foundation slowly disintegrated.

Cracking and collapsing structures are a growing problem in cities like Norilsk—a nickel-producing centre of 177,000 people located 180 miles above the Arctic Circle—as climate change thaws the perennially frozen soil and increases precipitation. Valery Tereshkov, deputy head of the emergencies ministry in the Krasnoyarsk region, wrote in an article this year that almost 60 percent of all buildings in Norilsk have been deformed as a result of climate change shrinking the permafrost zone. Local engineers said more than 100 residential buildings, or one-tenth of the housing fund, have been vacated here due to damage from thawing permafrost.

In most cases, these are slow-motion wrecks that can be patched up or prevented by engineering solutions. But if a foundation shifts suddenly it can put lives at risk: cement slabs broke a doctor’s legs when the front steps and overhanging roof of a Norilsk blood bank collapsed in June 2015. Building and maintenance costs will have to be ramped up to keep cities in Russia’s resource-rich north running.

Engineers and geologists are careful to note that “technogenic factors” like sewer and building heat and chemical pollution are also warming the permafrost in places like Norilsk, the most polluted city in Russia.

As always, creative science fiction authors offer possible solutions. In his 1970 novel Tower of Glass, Robert Silverberg tries to solve the problem of how to build a great tower in an unstable tundra:

From the tower's huge octagonal base radiate wide silvery strips of refrigeration tape, embedded fifty centimeters deep in the frozen carpet of soil, roots, moss, and lichens that is the tundra. The tapes stretch several kilometers in each direction. Their helium-II diffusion cells soak up the heat generated by the androids and vehicles used in building the tower. If the tapes were not there, the tundra would soon be transformed by the energy-output of construction into a lake of mud; the colossal tower's foundation-caissons would lose their grip, and the great building would tilt and tumble like a felled titan...
