Local flora 40 thousand years disappeared under the ice.
Scientists from the University of Colorado (USA) found that climate change faster strips of the Arctic landscape, not seeing the Sun for 40 thousand years or more.
The researchers published the data from the soil analysis on Baffin island – an island in the canadian province of Nunavut.
Deep fjords, ancient glaciers made it an ideal place to study the glacial period. So, a paleoclimatologist and geologist Gifford Miller of the University of Colorado every year come here for the last 40 years. He discovered disturbing changes.
According to him, the Arctic is warming two to three times faster than the rest of the world. If the trend continues, all the glaciers on the island will disappear. It is only a matter of time.
Part of the soil is already exposed after the melting of the skin. Miller and his team selected 48 samples of mosses and lichens, freed from under the ice sheet. Samples were taken from 30 different “ice caps”.
Radiocarbon Dating showed that the plants were under ice during the last 40 thousand years, and some of them may, and for 120 thousand years.
“The crazy thing is that many of these mosses may begin to grow again, they are like zombies,” Miller said.
The study also found that the past century was the warmest in the region for 115 thousand years.
