Global Warming

Global warming is about to turn Sweden’s highest mountain into its second highest

The snow-capped southern peak of Lapland’s Kebnekaise, in the Scandinavian Mountains, reaches 2,097.5 meters (6,881.6 feet) above sea level, making it the highest point in Sweden. But not for long.

The 40-meter-thick glacier on top of it has been shrinking, on average, a meter a year for the past two decades. In 1901, when the southern peak was first measured, its elevation was 2,121 meters.

By next year, scientists at the University of Stockholm predict, Kebnekaise’s northern peak—which is solid rock—will likely become the tallest spot in the country.

The culprit? Climate change. A recent research paper that tracked 47 years of air-temperature records in Tarfala Valley, below the Kebnekaise glacier, found a significant warming trend. The period from 1995 to 2011 was 1.08°C warmer than the period from 1965 to 1994. Eight of the ten warmest years covered by the study occurred since 1999.
