Researchers studied melting ice on Canada's Baffin Island and discovered land that was hidden for more than 40,000 years.

They believe the Canadian Arctic is experiencing its warmest century of the past 115,000 years.

The vegetation found underneath the ice is most likely from its original growth period many years ago.

Scientists plan to carbon date and conduct further studies on the plants to learn more about the Arctic climate.

Melting ice is exposing hidden landscapes in the Canadian Arctic that haven't been seen in more than 40,000 years, new research published in Nature Communications reveals.

Unsurprisingly, the study suggests climate change is the driving force behind this record-breaking glacial retreat and with Arctic temps rising at increasing speed thanks to strong positive feedback loops in the polar regions, we can expect things to heat up even quicker in the near future. According to researchers at the University of Colorado at Boulder, the Canadian Arctic may be seeing its warmest century in as many as 115,000 years.

"The Arctic is currently warming two to three times faster than the rest of the globe, so naturally, glaciers and ice caps are going to react faster," Simon Pendleton, the lead author and a doctoral researcher in Colorado Boulder's Institute of Arctic and Alpine Research, said in a statement.

Pendleton and colleagues' research is based on plants collected at the edge of ice caps on Baffin Island, the fifth-largest island in the world. The landscape is dominated by deeply incised fjords and high-elevation, low-relief plateaus. The latter conserves lichens and moss in their original position in the ice for periods of time lasting thousands of years — a little like a cryogenic chamber.

Previous observations indicate that foliage is soon "removed" from the environment once it loses that protective ice layer, either by meltwater in the summertime or wind-blown snow in winter. This lets scientists make a reasonable assumption that vegetation collected today is vegetation that has been covered in ice since its original growth period. As such, it offers a pretty decent barometer for how far and how quickly glaciers are retreating.

"We travel to the retreating ice margins, sample newly exposed plants preserved on these ancient landscapes, and carbon date the plants to get a sense of when the ice last advanced over that location," Pendleton said.

"Because dead plants are efficiently removed from the landscape, the radiocarbon age of rooted plants define the last time summers were as warm, on average, as those of the past century."

In total, the team collected 48 plant samples from 30 ice caps on Baffin Island as well as quartz samples, which were used to help confirm the age and ice cover history of the environment. Analysis in the lab suggests that plants in all 30 ice caps were likely to have been preserved in a constant sheet of ice for the past 40,000 years — or longer.

The results were then compared to temperature data recovered from ice cores in Greenland and Baffin Island, which imply temperatures over the past 100 years have been the warmest in the region for 115,000 years.

"Unlike biology, which has spent the past 3 billion years developing schemes to avoid being impacted by climate change, glaciers have no strategy for survival," the senior author Gifford Miller, a professor of geological sciences at Colorado Boulder, explained.

"They're well behaved, responding directly to summer temperature. If summers warm, they immediately recede; if summers cool, they advance. This makes them one of the most reliable proxies for changes in summer temperature."

And what with atmospheric carbon dioxide set to spike once again in 2019, we can expect more of these warm summers.

"We haven't seen anything as pronounced as this before," Pendleton added.
