Frozen Soils could be a Significant Wellspring of Sending out Greenhouse Gases

Based on a new study that has been done by researchers and also published in the Journal Magazine, thawing permafrost in the Arctic and sub-Arctic regions probably will produce and free a gradual and prolonged release of large quantities of greenhouse gases. Researchers have been working to understand the relationship between human-driven emission of carbon dioxide and its effect on the release of carbon dioxide from arctic permafrost. As permanently frozen soil continues to thaw, the increase of greenhouse gas emissions could increase warming conditions changes’ velocity on Earth.

Prof Ted Schuur of Northern Arizona University, who is the first author on the Nature Paper said: “Our big question is how much, how fast and in what form will this carbon come out. Human activities might start something in motion by releasing carbon gases but natural systems, even in remote places like the Arctic, may add to this problem of climate change”.

The co-author, Dr A. David McGuire of the U.S. Geological Survey and the U.S of Alaska Fairbanks Institute of Arctic Biology said: “The data from our team’s syntheses don’t support the permafrost carbon bomb view.”

He also continued: “What our syntheses do show is that permafrost carbon is likely to be released in a gradual and prolonged manner, and that the rate of release through 2100 is likely to be of the same order as the current rate of tropical deforestation in terms of its effects on the carbon cycle.”

Prof Schuur and his team hope this new finding will help to find solutions to decrease the effects on climate models.
