The First Glacier Killed by Climate Change Is Getting a Haunting Memorial Plaque in Iceland

Vikings thought it was a dead troll. Now, it's just dead ice.

Okjökull (or just "Ok," for short) is one of 400 ancient glaciers crowning the mountains of Iceland — at least, it was, until global warming shrank it so much that Ok officially lost its glacier status in 2014.

While Ok was the first casualty of climate change in Iceland, it probably won’t be the last. Iceland's glaciers are losing about 10 billion tons of ice every year, and all 400 of them will likely follow in Ok's cold, wet footsteps by the year 2200 without a serious reduction in greenhouse gas emissions in the coming decades.

Now, to memorialize the loss of Ok and the hundreds of other Icelandic glaciers that may share Ok's fate, researchers from Iceland and the United States have created a memorial plaque to forever mark the spot where Ok once towered over the landscape.

The plaque, which will be officially dedicated in an Aug. 18 ceremony at the site of the former glacier, is addressed simply to "the future" and sends a hauntingly simple message.

"Ok is the first Icelandic glacier to lose its status as a glacier," the plaque reads. "In the next 200 years all our glaciers are expected to follow the same path. This monument is to acknowledge that we know what is happening and what needs to be done. Only you know if we did it."

The text concludes with "415ppm C02," the current ratio of greenhouse gases in Earth's atmosphere — and likely the highest amount our planet has seen since before humans evolved.

"This will be the first monument to a glacier lost to climate change anywhere in the world," Cymene Howe, an anthropologist at Rice University in Houston and co-creator of a 2018 documentary on Ok, said in a statement. "By marking Ok's passing, we hope to draw attention to what is being lost as Earth's glaciers expire. These bodies of ice are the largest freshwater reserves on the planet and frozen within them are histories of the atmosphere."

Howe and her fellow researchers will install the plaque as part of an "un-glacier tour," which will depart from Reykjavík and lead participants on a free hike to the former site of Ok. Participants should expect rocky terrain.
