Glacial Melting Isn’t Someone Else’s Problem

Glacial Melting Isn’t Someone Else’s Problem

High in the Ecuadorian Andes, the peak of Cotacachi was once reliably white. But by the early 2000s, the glacier on top of this dormant volcano, which reaches more than 16,200 feet, had disappeared. This made it—as anthropologist Robert E. Rhoades and his co-authors Xavier Zapata Ríos and Jenny Aragundy Ochoa wrote in the 2008 book Darkening Peaks—one of “the first Andean mountains in the past half-century to completely lose its glacier as a result of recent accelerated global warming.”

As many glaciers throughout the world are retreating at faster rates, they have become powerful symbols of global warming. But glacial retreat is still an abstract idea for many people, which makes it easy to ignore. As environmental historian Mark Carey puts it, “Most people in the United States have never encountered a glacier; nor would they be able to identify one even from close proximity.” Yet due to global interconnection, our actions have far-flung consequences—in unfamiliar landscapes and in places we cannot see.

In communities from the Andes to the Alps to the Himalayas, glacial loss affects people’s lives in concrete ways. In Ecuador, when the last ice crystals from Cotacachi’s glacier melted, a once-reliable source of water evaporated. According to farmers in the area, it also doesn’t rain as much as it used to, Rhoades and his co-authors wrote in Darkening Peaks. The combined effect of less rainfall and drier rivers and streams has made agriculture more challenging, as multiple consequences of climate change intersect.

In some places where glaciers are retreating, meltwater provides a temporary windfall for these communities—by producing more water for irrigation. Yet water quality can also be compromised: As the journalist Nicholas Casey recently wrote in The New York Times, heavy metals exposed by glacial retreat in Peru “are now leaking into the ground water supply, turning entire streams red, killing livestock and crops, and making the water undrinkable.”

While receding glaciers expose rocky mountain peaks, they also expose the complexity of social connections. As anthropologist Ben Orlove and his co-authors Ellen Wiegandt and Brian H. Luckman wrote in their chapter in Darkening Peaks, “The global scale of climate change means that the people most directly affected by glacier retreat make a very small direct contribution to the worldwide emissions of greenhouse gases that are its root cause. As a consequence, their behavior will have little impact on the future course of this shrinkage.”

This global inequality is one of the greatest tensions at the heart of climate change. According to data from the World Bank, for example, while the United States emitted 16.49 metric tons of carbon dioxide per person in 2014, Ecuador emitted 2.76 metric tons per person.

Because the United States and many countries in the European Union have historically emitted a far greater global share of carbon emissions, representatives from the global south have argued that they should also bear greater responsibility in responding to global climate change.

As for the communities that live near glaciers, is there anything they can do? There is no equivalent of a tree-planting campaign to respond to glacier loss. Even so, in the Alps, some communities have covered parts of glaciers with synthetic fleece blankets and foam—but while such efforts may slow glaciers’ retreat, they can’t stop it.

What about the rest of us, then—those of us who may never see a glacier, but whose lifestyles are contributing to global warming? How should we respond to communities who are losing the glaciers they have lived with—and, in many cases, depended upon—for centuries? What steps will we take to reduce greenhouse gas emissions, and to hold our public officials accountable? These are just a few of the many difficult questions that we should be asking ourselves.

Meanwhile, the glaciers keep melting.
