Global Warming: Who Loses—and Who Wins?

Coastal cities inundated, farming regions parched, ocean currents disrupted, tropical diseases spreading, glaciers melting—an artificial greenhouse effect could generate countless tribulations.

If Earth’s climate changes meaningfully—and the National Academy of Sciences, previously skeptical, said in 2005 that signs of climate change have become significant—there could be broad-based disruption of the global economy unparalleled by any event other than World War II.

nearly all the added land-value benefits of a warming world might accrue to Alaska, Canada, Greenland, Russia, and Scandinavia.

And Russia! For generations poets have bemoaned this realm as cursed by enormous, foreboding, harsh Siberia. What if the region in question were instead enormous, temperate, inviting Siberia? Climate change could place Russia in possession of the largest new region of pristine, exploitable land since the sailing ships of Europe first spied the shores of what would be called North America. The snows of Siberia cover soils that have never been depleted by controlled agriculture. What’s more, beneath Siberia’s snow may lie geologic formations that hold vast deposits of fossil fuels, as well as mineral resources. When considering ratification of the Kyoto Protocol to regulate greenhouse gases, the Moscow government dragged its feet, though the treaty was worded to offer the Russians extensive favors. Why might this have happened? Perhaps because Russia might be much better off in a warming world: Warming’s benefits to Russia could exceed those to all other nations combined.

If climate change causes developing nations to falter, and social conditions within them deteriorate, many millions of jobless or hungry refugees may come to the borders of the favored North, demanding to be let in. If the very Earth itself turns against poor nations, punishing them with heat and storms, how could the United States morally deny the refugees succor? [Have to point out that the U.S. often does not act morally.]

Shifts in the relative values of places and resources have often led to war, and it is all too imaginable that climate change will cause nations to envy each other’s territory.

Oh, and there may be oil under the arctic waters. Who would own that oil? The United States, Russia, Canada, Norway, and Denmark already assert legally complex claims to parts of the North Pole seas—including portions that other nations consider open waters not subject to sovereign control. Today it seems absurd to imagine the governments of the world fighting over the North Pole seas, but in the past many causes of battle have seemed absurd before the artillery fire began. Canada is already conducting naval exercises in the arctic waters, and making no secret of this.

Recent studies show that in the last few decades, precipitation in North America is increasingly the result of a few downpours rather than lots of showers. Downpours cause flooding and property damage, while being of less use to agriculture than frequent soft rains.

Why, ultimately, should nations act to control greenhouse gases, rather than just letting climate turmoil happen and seeing who profits? One reason is that the cost of controls is likely to be much lower than the cost of rebuilding the world. Coastal cities could be abandoned and rebuilt inland, for instance, but improving energy efficiency and reducing greenhouse-gas emissions in order to stave off rising sea levels should be far more cost-effective. Reforms that prevent major economic and social disruption from climate change are likely to be less expensive, across the board, than reacting to the change. The history of antipollution programs shows that it is always cheaper to prevent emissions than to reverse any damage they cause.
