Images of Scarcity

NEW HAVEN – Could the television image we’ve all seen of the Greenland ice cap crumbling into the ocean because of global warming somehow – indirectly and psychologically – be partly responsible for high oil and other commodity prices?

The usual explanation of today’s scarcity and high prices focuses on explosive growth in emerging countries, China and India in particular, whose demand for scarce resources is “insatiable.” But psychology also matters in speculative markets, and perhaps that image of the Greenland ice disappearing makes it seem all too plausible that everything else– land, water, even fresh air – is running out too.
