New research finds Arctic Summers summers are hottest in 115,000 years



New evidence has led researchers to point out that the Arctic is experiencing its hottest temperatures for 115,000 years, according to a new report.

Posted in Nature Communications on Friday, the new report titled: "The Glaciers of the Canadian Arctic That Are Quickly Removing Revealing Ice-Covered Landscapes for Over 40,000 Years" revealed that summers in the wilderness of the The Canadian Arctic had not known such hot temperatures for at least 115,000 years.

The new study "indicates that we are now exhibiting 120,000-year-old landscapes," said lead author Simon Pendleton of the Arctic Research Institute. and the Alpine of the University of Colorado, quoted by Gizmodo.com.

"Our last century of heat is probably better than the last 120,000 years," Pendleton added.

Researchers involved in the new report investigated the geographic anomalies and ancient ice on Baffin Island in Canada, particularly in the highland ice caps and deep fjords.

Ice caps, unlike glaciers, do not move, and matter resting on the ground on which they are formed is kept as long as the cap remains in place.

While global warming caused by man-made climate change is disrupting the balance of the ice sheets – and the rest of the planet – it has been shown that the Arctic is warming up. twice as fast as anywhere else, according to a lot of research.

As holiday melting rates increase in Arctic regions, large amounts of old moss and lichen – among other things – are exposed to the edges of the rapidly retiring ice.

During the collection of samples and radiocarbon dating, the researchers found that the mosses were at least about 40,000 years old and constituted a known ice age in the northern hemisphere.

Pendleton and his team then compared their findings with several sources, including ice measurements from neighboring Greenland, and discovered that the area was frozen for a much longer period than 40,000 years, which led them to find that highest at any time between 115,000 and 120,000 years, according to Gizmodo.com.

According to the researchers, the melting of the ice cap will expose more old earth, which will allow scientists to predict changes in the Arctic. Even without the use of radiocarbon dating, the ecosystem of Baffin Island and its surrounding area is changing rapidly and changes are becoming more visible.

"See it, walk on the ice cap and understand that we are in a period that exposes landscapes that have not seen the sun for 120,000 years," said Pendleton, "has a profound effect," cited by Phys.org.
