It was designed as an impregnable deep-freeze to protect the worlds most precious seeds from any global disaster and ensure humanitys food supply forever. But the Global Seed Vault, buried in a mountain deep inside the Arctic circle, has been breached after global warming produced extraordinary temperatures over the winter, sending meltwater gushing into the entrance tunnel.
The vault is on the Norwegian island of Spitsbergen and contains almost a million packets of seeds, each a variety of an important food crop. When it was opened in 2008, the deep permafrost through which the vault was sunk was expected to provide failsafe protection against the challenge of natural or man-made disasters.
But soaring temperatures in the Arctic at the end of the worlds hottest ever recorded year led to melting and heavy rain, when light snow should have been falling. It was not in our plans to think that the permafrost would not be there and that it would experience extreme weather like that, said Hege Njaa Aschim, from the Norwegian government, which owns the vault.
