It is normal for a portion of a glacier to melt and refreeze seasonally and to shift slightly each year. But in the past three decades, rising temperatures have brought a worryingly rapid thaw, particularly tangible on small glaciers like Grafferner. "In one century, we have lost seventy percent of the glaciated surface," said Bondesan, a coordinator for the Italian Glaciological Committee. "Scientists don't have enough information to understand if this is a temporary change—induced by man, that's quite sure—or just a fluctuation that is going to recover in ten or one hundred years," he said, his mustache crusted with ice and remnants of the speck we ate for breakfast at Pension Leithof in Vernago, a European skiing destination on the Italian side of the valley."Even the biggest and most stable things, like glaciers, mountains—these huge objects, they can change in a few years. We live on a planet that changes, and we try to make rules, to give meaning, but this meaning is completely artificial because nature, basically, doesn't give a shit." —Marco Ferrari
The GPS sensors sit on top of the glacier, measuring its coordinates as it slides. A member of the Italian Glaciological Committee said, "In one century, we have lost seventy percent of the glaciated surface."
While an ambling boundary on a glacier, five and a half hours' walk from the nearest town and in a relatively peaceful part of Europe, may not seem like the stuff of heated political discourse, there has always been tension between Austrians and Italians in the South Tyrol region, which was handed back to Italy after WWII. German-speaking vandals often steal the Italian-language signs marking the Similaun hiking trails in protest.On our way home, we stopped in the town of Bolzano, where a Mussolini-era Victory Gate recalls the city's Fascist heritage. The government fenced off the 62-foot-wide monument, still an epicenter of friction between the Italian- and German-speaking communities, to protect it from vandalism.
Over a drunken dinner, Italian resident and design lecturer at the Free University of Bozen-Bolzano Simone Simonelli told me that cultural and attitudinal tensions still bubbled beneath the surface of the placid town. Strolling through Bolzano that day, Simonelli had come across a small right-wing anti-migrant protest. The following afternoon, Austrian police clashed with 500 Italian activists calling for a more welcoming attitude to refugees at the Brenner Pass border, where in recent months thousands of migrants have tried to come through under Europe's Schengen Agreement open-border policy. By the end of the month, the Austrian government had begun construction of a barbed-wire fence to curb the influx.We have killed 10 percent of the world's coral reefs, endangered a third of amphibian species, created an oceanic garbage patch twice the size of the United States, and are at risk of losing our primary freshwater resource: the glaciers.
