NORTH RIM

WILL WE DECAMP FOR THE NORTHERN RIM?
By Laurence C. Smith

"Already the impacts are obvious in the extreme north, where melting Arctic sea ice, drowning polar bears, and forlorn Inuit hunters are by now iconic images of global warming. The rapidity and severity of Arctic warming is truly dramatic. However, the Arctic, a relatively small, thinly populated region, will always be marginal in terms of its raw social and economic impact on the rest of us. The greater story lies to the south, penetrating deeply into the "Northern Rim," a vast zone of economically significant territory and adjacent ocean owned by the United States, Canada, Denmark, Iceland, Sweden, Norway, Finland, and Russia. As in the Arctic, climate change there has already begun. This zone — which constitutes almost 30 percent of the Earth’s land area and is home to its largest remaining forests, its greatest untouched mineral, water, and energy reserves, and a (growing) population of almost 100 million people — will undergo one of the most profound biophysical and social expansions of this century."

LAURENCE C. SMITH is Professor and vice chairman of geography and professor of earth and space sciences at UCLA. He studies likely impacts of northern climate change including the economic effects in the Northern Rim.
