Studies of Danish scientists say that about 500,000 years ago Greenland was not covered with snow and ice cap, and was a flourishing island with the development of flora and fauna. Danish and Swedish experts argue that ancient Greenland climate was relatively mild.
"About 10% of the Earth is covered with a thick layer of ice. No one knows what is on the kilometer depth — is the most mysterious regions of our planet "- says Professor at the University of Copenhagen (Denmark) Eske Willerslev.
With the help of kilometer of wells drilled in the area of permanent ice in Greenland, the researchers took samples of organic sediments, soil and ice. Experts say that the ice at the base of the glacier very different from the surface of the ice, and it is quite logical, since they were formed in very different conditions.
The lower layers are mixed with the soil and it is in these layers, scientists and discovered the remains of ancient life, clearly points to a warmer climate in Greenland 500,000 years ago. Willerslev notes that Greenland's glaciers may be conditionally divided into three parts: The first segment of glaciers formed about 450 000 — 125 000 years ago, the second 125 000 — 10 000 years ago, and the third part was formed about 10,000 years ago. The upper part of the glacier on the structure and properties similar to the glaciers of Canada, which is also about 10 000 years.
"Genetic material extracted from beneath the ice is quite different from the modern vegetation, indicating that their own biological system in Greenland. We concluded that about 500,000 years ago in Greenland grew some wild grain, pine, larch and alder. In other words all that nowadays can be found in the south of Sweden or Canada. The presence of these trees and plants suggests that the winter temperature there did not fall below minus 17 degrees Celsius in the summer — below 10 "- he says.
Danish researchers say that today was not found any evidence of the existence of animals and insects, but if on the island attended the forests and grasslands is reasonable to assume that they might dwell at least insects, butterflies and a variety of small terrestrial creatures such as beetles.
However, modern scientific theories suggest that the south and north of Greenland cold with a difference of 125 000 years, and the temperature difference between the southern and northern borders of the island were not less than 5 degrees. This may reflect the fact that even before freezing ecosystems north and south of Greenland have been different.
