The polar winter is unrivalled in its harshness and night that lasts for months, only the toughest day, as temperatures plunge/ to minor 70 degrees centigrade. And yet the greatest challenge to life here is not the cold, but the extreme swings between the seasons.

 

    When the sun finally returns, an extraordinary transformation begins. This frozen world begins to melt away. The polar spring brings views of a brief opportunity for life. By summer, the sun no longer sets and works its magic for 24 hours a day. Now, it's a race to breed before the sun departs .By autumn, all but the hardiest abandon/ the poles and the ice extends its grip. Land and sea close/ down for the long polar winter until once again the sun returns.
