Receding Sea Ice in the Arctic, and Increased Interest in Developing its Resources, What Do We Need to Know

via National Geographic

The Arctic is currently changing in ways we are still trying to grasp, but it is already dramatically, undeniably different than it was just 30 years ago. The white cover of sea ice that blankets the Arctic is receding dramatically in the summer months. Satellite data show the September minimum has shrunk by more than 11 percent per decade since 1979, researchers say.
As the volume and frequency of open water in the Arctic grows, so too does activity by oil and gas, shipping, mining, and other industries. Ship transit through the Bering Strait, the gateway from the North Pacific Ocean to the Arctic, more than doubled between 2008 and 2012, and sea traffic throughout the region continues to grow exponentially as it provides a shorter cargo route between Asia and Europe. At the same time, several companies seek to mine reserves that could contain as much as 22 percent of the world’s undiscovered conventional oil and gas.
