Temperatures dropped and big, unseasonal flakes of snow swirled in the breeze earlier this week in Copenhagen, turning skies gray and streets slippery. But the change discussed in conversations wherever you go in this ornately decorated city is not the week’s weather but the coming century’s climate. Nowhere does climate change feel more ominous than at the North Atlantic House, a cultural centre in central Copenhagen celebrating the Arctic peoples of Iceland, Greenland and the Faroe Islands. An artist from Greenland turned the North Atlantic House building into a massive art installation symbolising global warming. The front of the 250-year-old former warehouse shimmers with what appears like a 6-story iceberg popping out of its façade, but it’s literally only the tip of the iceberg. Inside, several exhibitions document changes brought to the Arctic by global warming, and forecast the more dramatic transformations expected in the future.
