As climate change causes the polar ice caps to melt and the sea levels to rise, new sea routes are beginning to emerge, which could present a threat to Euro-Atlantic security. Greenland is considered by scientists to be ground zero for climate change. Along with the Faroe Islands, it forms part of the Kingdom of Denmark and is therefore under Danish military protection. That protection falls to the Joint Arctic Command, or JACO, a Danish-led operational command with a central headquarters in Nuuk, Greenland’s capital.
