Close up of water and sewage pipelines, raised above the ground because the permafrost is subsiding underneath. These pipes, underneath buildings' concrete foundations, are insulated as in winter the surface temperature can drop below -30 degrees. If the permafrost continues to thaw these pipes and other infrastructures will become unstable, risking to crack and collapse. The whole region is under heavy threat from global warming as temperatures increase and Russia’s ancient permafrost melts.
