By the end of the century, near-surface permafrost may exist only in the highlands of eastern Siberia, the High Arctic and northern Greenland. As was the case 3 million years ago<\/h2>\n

Most of the near-surface permafrost<\/strong> could disappear between now and 2100. This is claimed by a study<\/a> by a team of scientists from the United States, Russia, the United Kingdom, Germany, Japan, Canada, the Netherlands, France and Sweden. The team, led by Donglin Guo<\/strong>, a researcher at the Chinese Academy of Sciences and Nanjing University, compared the current climate scenario with that of millions of years ago. The results were published in the journal Proceedings of the National Academy of Sciences.<\/p>\n

“Our study indicates dramatically smaller-than-present near-surface permafrost extent in the geological past, under climate conditions analogous to those expected if global warming continues unabated,” write the authors quoted in a statement<\/a> released by the Fairbanks Geophysical Institute at the University of Alaska<\/strong>.<\/p>\n
