Arctic Summers has been hotter for 115,000 years, says new research



According to new findings, researchers have discovered in detail that the Arctic is experiencing the hottest temperatures in 115,000 years, according to a new report.

The new report released in Nature Communications on Friday entitled: "Fast-Falling Arctic Glaciers in Canada" landscapes that have been covered with ice continuously for more than 40,000 years, have shown that the summers in Canada's Arctic wilderness has not had such warm temperatures for at least 115,000 years.

The new study "indicates that we are now exposing 120,000-year-old landscapes," noted lead author Simon Pendleton from the University of Colorado's Institute of Arctic and Alpine Research, cited by Gizmodo.com.

"Our last century heat is likely to be greater than any century in the past 1

20,000 years," Pendleton added.

Researchers investigated geographic anomalies and old ice on Canada's Baffin Island, especially in high plateau ice caps and deep fjords

Unlike glaciers, icecaps do not move and the matter on the ground on which they are formed remains as long as the cap stays in place.

With global warming caused by human-induced climate change confusing the balance of ice caps – as well as anything else on Earth – the Arctic has, after extensive research, proved twice as fast as any other country.

As summer smelting rates increase in the Arctic regions, old mosses and lichens, among others, are exposed on the edges of the rapidly retreating ice.

When the researchers collected samples and performed radiocarbon dating, they found that the mosses were at least 40,000 years old, a well-known ice age in the northern hemisphere.

Pendleton and his team compared their findings to multiple sources, including ice measurements from nearby Greenland, and found this The region has been iced over a period of more than 40,000 years, suggesting that the current Arctic summer temperatures are now higher at any time in 115,000-120,000 years after Gizmodo.com.

More ice-cap meltings will expose more ancient land, researchers say, so scientists can predict increasing changes in the Arctic. Even without radiocarbon dating, the ecosystem of Baffin Island and its surroundings are changing rapidly and changes are becoming more apparent.

"To see it and walk on the icecap and understand that we are in an era of exposing landscapes that have not seen sunlight in 120,000 years," Pendleton said, "has a profound effect ", quoted by Phys. org.
