Canadian Arctic glacial melt: Landscapes revealed for 40,000 years



And one big takeaway is this: The Arctic might have been its warmest century at least.

"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 covered in a broad geographic region of Baffin Island."

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.

40,000 years, said University of Colorado Boulder doctoral researcher Simon Pendleton, lead author of the study.

The plants were found in the Penny Ice Cap area of ​​the island, in elevations ranging from several hundred meters to a mile above sea level.

"You'd normally expect to see different plants in different topographical conditions , for example, "Pendleton said in a statement from the university.
 Antarctica ice melt accelerated by 280% in the last 4 decades

Though they are 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 Pendleton said

The findings about the plants, 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.
