"When the permafrost thaws in an ever-higher tempo gives the ground to fold and landscapes change. It can lead to that the carbon emissions are doubled compared with the previous projections, according to a new study."
"The frozen ground in the tundra and forests hiding the amounts of environmentally hazardous greenhouse gases. The permafrost has slowly begun to thaw and the negative impact on the climate can be twice as large as expected, according to a new international study published in the journal Nature."
"– If the global warming continues so will the emissions from the permafrost correspond to about 20% of what we humans emit annually, " says Gustaf Hugelius, senior lecturer at the Department of physical geography at Stockholm university and one of the researchers behind the study."
"Scientists from several countries have looked at how the thawed ground, transforming the landscape. When the ice melts, draining the water away, which makes the chips collapses. This in turn may lead to waterlogging or landslides."
"– Then exposed the permafrost to the warm air and it can contribute to a local crisis. It is a process that we have seen for a long time but it is happening in an increasingly rapid pace, " says Gustaf Hugelius."
"Permafrostjordarna covers roughly a quarter of the northern hemisphere and contains all 1 600 billion tonnes of carbon, almost twice as much as in the atmosphere. A collapse affecting the frozen ground all the way down on the depth and makes the powerful greenhouse gas methane is released."
" It is important that you have this in mind, for example, when the countries negotiate emission targets. You must take into account the natural emissions as well."
"the Permafrost reacts relatively slowly warming so the big impact, we will not see until the end of this century, according to Gustaf Hugelius. It means that it is still possible to slow down the thawing."
"– There is a window of roughly a decade to reduce greenhouse gas emissions and limit global warming to 1.5 degrees. Then we will be able to save the majority of the permafrost, " he says."
"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."
"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."
