Many oil and gas operations, mines and construction projects in the Arctic areas of Canada, Alaska, Scandinavia and Russia depend on cold, solid ground and winter roads over frozen lakes and rivers to transport heavy equipment, fuel and supplies. Located where there are few traditional road networks, such operations and their personnel depend on months of frigid winter temperatures that make it possible to access resources that might not be economically viable if access were only by air or sea. Yet the changing global climate is reducing the number of weeks of dependable cold weather, placing the solid ground and ice roads in peril.
