We May Be in for a Movie-like Apocalyptic Event: Hunger Games for Real

Continued from previous page

Once again, a surge in food prices resulted in widespread social unrest, this time concentrated in North Africa and the Middle East. The earliest protests arose over the cost of staples in Algeria and then Tunisia, where -- no coincidence -- the precipitating event was a young food vendor, Mohamed Bouazizi , setting himself on fire to protest government harassment. Anger over rising food and fuel prices combined with long-simmering resentments about government repression and corruption sparked what became known as the Arab Spring. The rising cost of basic staples, especially a loaf of bread, was also a cause of unrest in Egypt, Jordan, and Sudan. Other factors, notably anger at entrenched autocratic regimes, may have proved more powerful in those places, but as the author of Tropic of Chaos , Christian Parenti, wrote, “The initial trouble was traceable, at least in part, to the price of that loaf of bread.”

As for the current drought, analysts are already warning of instability in Africa, where corn is a major staple, and of increased popular unrest in China, where food prices are expected to rise at a time of growing hardship for that country’s vast pool of low-income, migratory workers and poor peasants. Higher food prices in the U.S. and China could also lead to reduced consumer spending on other goods, further contributing to the slowdown in the global economy and producing yet more worldwide misery, with unpredictable social consequences.

The Hunger Games, 2012-??

If this was just one bad harvest, occurring in only one country, the world would undoubtedly absorb the ensuing hardship and expect to bounce back in the years to come. Unfortunately, it’s becoming evident that the Great Drought of 2012 is not a one-off event in a single heartland nation, but rather an inevitable consequence of global warming which is only going to intensify.  As a result, we can expect not just more bad years of extreme heat, but worseyears, hotter and more often, and not just in the United States, but globally for the indefinite future.

Until recently, most scientists were reluctant to blame particular storms or droughts on global warming.  Now, however, a growing number of scientists believe that such links can be demonstrated in certain cases. In one recent studyfocused on extreme weather events in 2011, for instance, climate specialists at the National Oceanic and Atmospheric Administration (NOAA) and Great Britain’s National Weather Service concluded that human-induced climate change has made intense heat waves of the kind experienced in Texas in 2011 more likely than ever before. Published in the Bulletin of the American Meteorological Society , it reported that global warming had ensured that the incidence of that Texas heat wave was 20 times more likely than it would have been in 1960; similarly, abnormally warm temperatures like those experienced in Britain last November were said to be 62 times as likely because of global warming.

It is still too early to apply the methodology used by these scientists to calculating the effect of global warming on the heat waves of 2012, which are proving to be far more severe, but we can assume the level of correlation will be high. And what can we expect in the future, as the warming gains momentum?

When we think about climate change (if we think about it at all), we envision rising temperatures, prolonged droughts, freakish storms, hellish wildfires, and rising sea levels. Among other things, this will result in damaged infrastructure and diminished food supplies.  These are, of course, manifestations of warming in the physical world, not the social world we all inhabit and rely on for so many aspects of our daily well-being and survival. The purely physical effects of climate change will, no doubt, prove catastrophic.  But the social effects including, somewhere down the line, food riots, mass starvation, state collapse, mass migrations, and conflicts of every sort, up to and including full-scale war, could prove even more disruptive and deadly.
