"the Permafrost on earth has become increasingly warmer over the last decade, according to a new study. The risk has increased that significant areas will melt and contribute to the ongoing global warming."
"– It may be that we do not have any permafrost left in many places at the end of this century, for example, in Sweden, " says Britta Sannel, a researcher at Stockholm university and one of the participants in the study."
"the Majority of the world's permafrost found in the Arctic and the Antarctic, where it binds large amounts of carbon. If it would thaw releases carbon dioxide and methane, which are looking up in the atmosphere."
"In the study, published in Nature Communications, has Sannel and colleagues from several different countries, and summarized the results from 150 boreholes drilled throughout the earth, in areas with permafrost."
"the Scrutiny shows that the temperature in the permafrost have risen by an average of 0.3 degrees between 2007 and 2016. The reason is in the first instance, rising air temperatures."
"This is serious because snittemperaturerna in the permafrost in the ytterkantsområdena is located just above 0 degrees."
"– There is a great risk for the frost to melt, even with small changes, " says Sannel."
"She points out that melting has already taken place in several areas, including in Sweden and in western Alaska."
"the Permafrost, or permanent ground frost, is the ground that is frozen for at least two years in a row."
"Permafrost occurs mainly in Arctic, Antarctic and in certain mountainous regions, such as Tibet. The depth may be several hundred meters in northern Siberia and northern north America. The top layer of the frost thaws in general in the summer."
