Recent climatic changes due to environmental pollution might be much more extreme as opposed to previous scientific calculations. In a recent study, it was revealed that the permafrost found over the Arctic could actually melt much sooner than expected previously. The greenhouse gas influx has led to thawing of the permafrost which could melt down in a time frame of few decades states the study conducted by NASA.
Permafrost is a permanently frozen part of the Arctic soil that is a massive carbon store locked underground. While we add to the pollution level with the heat levels rising in the atmosphere, the permafrost has been thawing at a rapid rate. The microbes in the soil of the permafrost tend to turn the carbon into greenhouse gases such as methane and carbon dioxide leading to further contribution to global warming.
The instances of abrupt thawing that had been relatively low in the past might increase following the increase in surrounding climate which adds to the greenhouse gas level. The study of this rapid thawing was published in the journal named Nature Communications. This abrupt thawing actually takes place below a specific variety of the Arctic Lake which has been termed as the thermokarst Lake which is formed as the permafrost thaws.
The lead author of the study Katey Water Anthony at the University of Alaska Fairbanks stated that this abrupt thawing mechanism tends to matter a lot especially when it leads to the formation of thermokarst Lake leading to an increased level of permafrost based carbon feedback to the environment in a century. Apparently the human civilization won’t have to wait 300 or even 200 years to see these massive released of carbon from the permafrost. It can actually be aptly visible just within a few decades given the fact that it has been thawing at an accelerated rate that is multiplying with every passing moment. Within the upcoming decades, the rate will surely peak.
The team comprised of Walter Anthony and researchers based from Germany and the U.S. used the combined effort from field measurements and computer models to get to the conclusion that these permafrost have been melting at a rate that id double the estimates derived previously while the same is increasing as each second passes by. It was found that this abrupt thawing process lead to an increased release of the ancient carbon that is stored inside the soil which marks the rate at 125-190 percent of the gradual thawing pattern.
