SANTA CRUZ PROVINCE, ARGENTINA - NOVEMBER 27:  Ice calves at the Perito Moreno glacier in Los Glaciares National Park, part of the Southern Patagonian Ice Field, the third largest ice field in the world, on November 27, 2015 in Santa Cruz Province, Argentina. The majority of the almost 50 large glaciers in Los Glacieres National Park have been retreating during the past fifty years due to warming temperatures, according to the European Space Agency (ESA). The United States Geological Survey (USGS) reports that over 68 percent of the world's freshwater supplies are locked in ice caps and glaciers. The United Nations climate change conference begins November 30 in Paris.  (Photo by Mario Tama/Getty Images)

(CNN) —  

Glaciers in the Canadian Arctic have melted enough to reveal land that was hidden for the last 40,000 years or more, researchers say.

And one big takeaway is this: The Arctic might be having its warmest century in at least 115,000 years, according to a study published this month in the journal Nature Communications.

“It’s not just a fluke,” University of Colorado Boulder doctoral researcher Simon Pendleton, lead author of the study, told CNN. “These ancient landscapes are being revealed over a broad geographic region on Baffin Island.”

For this study, scientists plucked 48 mosses and lichens – still rooted in the spots where they were killed by expanding ice millennia ago – from the edges of 30 retreating ice caps on Canada’s Baffin Island during summers from 2010 to 2015.

Using radiocarbon dating, the researchers found that most of the plants had been under the ice for at least 40,000 years, Pendleton said.

The plants were found in and around the island’s Penny Ice Cap region, in elevations ranging from several hundred meters to a mile above sea level. The recently exposed landscape, largely on plateaus between fjords, is dominated by boulders, bedrock and tundra vegetation.

“You’d normally expect to see different plant ages in different topographical conditions. A high elevation location might hold onto its ice longer, for example,” Pendleton said in a statement from the university. “But the magnitude of warming is so high that everything is melting everywhere now.”

Though they’re ancient, the collected plants are the same species as those that are alive and growing on the island today – not unusual, given that we’re looking at a span of tens of thousands of years as opposed to millions, Pendleton said.

The findings about the plants’ ages, combined with temperature data reconstructed from Greenland ice cores, suggest that this is the region’s warmest century in about 115,000 years, the study says.

“These trends are likely to continue and remove all ice from Baffin Island within the next few centuries, even in the absence of additional summer warming,” the study says.
