The Coming Arctic Boom: As the Ice Melts, the Region Heats Up
Climate change is transforming the Arctic from a geopolitical afterthought into an epic bounty ripe for this century’s entrepreneurs. Countries should continue their commitment to the peaceful course they have charted there so far. But policymakers need t

The Coming Arctic Boom: As the Ice Melts, the Region Heats Up Scott G. Borgerson
The ice was never supposed to melt this quickly. Although climate scientists have known for some time that global warming was shrinking the percentage of the Arctic Ocean that was frozen over, few predicted so fast a thaw. In 2007, the Intergovernmental Panel on Climate Change estimated that Arctic summers would become ice-free beginning in 2070. Yet more recent satellite observations have moved that date to somewhere around 2035, and even more sophisticated simulations in 2012 moved the date up to 2020. Sure enough, by the end of last summer, the portion of the Arctic Ocean covered by ice had been reduced to its smallest size since record keeping began in 1979, shrinking by 350,000 square miles (an area equal to the size of Venezuela) since the previous summer. All told, in just the past three decades, Arctic sea ice has lost half its area and three quarters of its volume. It’s not just the ocean that is warming. In 2012, Greenland logged its hottest summer in 170 years, and its ice sheet experienced more than four

times as much surface melting as it had during an average year over the previous three decades. That same year, eight of the ten permafrost-monitoring sites in northern Alaska registered their highest-ever temperatures, and the remaining two tied record highs. Hockey arenas in northern Canada have even begun installing refrigeration systems to keep their rinks from melting. Not surprisingly, these changes are throwing the region’s fragile ecosystems into chaos. While tens of thousands of walruses, robbed of their ice floes, are coming ashore in northwest Alaska, subarctic flora and fauna are migrating northward. Frozen tundras are starting to revert to the swamplands they were 50 million years ago, and storms churning newly open waters are eroding shores and sending the homes of indigenous populations tumbling into the sea. No matter what one thinks should be done about global warming, the fact is, it’s happening. And it’s not all bad. In the Arctic, it is turning what has traditionally been an impassible body of water ringed by remote wilderness into something dramatically different: an emerging epicenter of industry and trade akin to the Mediterranean Sea. The region’s melting ice and thawing frontier are yielding access to troves of natural resources, including nearly a quarter of the world’s estimated undiscovered oil and gas and massive deposits of valuable minerals. Since summer time Arctic sea routes save thousands of miles during a journey between the Pac
