The effects of climate change are happening all over the world. But its impact is first and foremost at the poles. By the way, the focus of researchers on the effects of climate change is more on the poles. Due to global warming, scientists are already worried about the melting of the ice sheets of the poles. Now scientists are studying the permafrost here, which is called permanently frozen land due to extreme cold. In this study, researchers have found that the area of the Arctic is warming three times faster than the rest of the world.
What are permanent frosts?
By the way, permanent frost is called that land that has been frozen for at least two consecutive years. One-fourth of the land of the Northern Hemisphere is found in the form of such land. This includes areas of the North Pole like Alaska, Sweden, Greenland, Siberia, and the many regions of the Himalayas and Tibet.
Methane leak from permanent frosts
Hydrogen sulfide, a swamp or swamp gas, is common from many permanent frost sites in the Arctic region and surrounding marshes, ponds, etc. Still, now the release of methane gas has become a matter of concern for environmentalists. Experts say that the carbon reserves locked in long-standing frosts have been opened.
Carbon time bum
These permanent frosts between carbon dioxide and methane contain about 1700 billion tons of organic carbon, twice the amount of carbon present in the atmosphere. Scientists say that permanent frosts are like a kind of carbon timebomb. Although methane can remain in the atmosphere for only 12 years, carbon dioxide remains for centuries. But this gas has been 25 times more powerful than other greenhouse gases, including CO2, for a hundred years.
Things were not like this forty years ago
Keith Larsson, project coordinator of the Climate Impacts Research Center at Ume University, working at Sweden’s Abisko Scientific Research Station, says that they started exploring the area when researchers began coming here in the 1970s.
A cyclical mechanism of climate change
In Nabisco, where permanent frosts are only a few meters thick, which are thousands of years old. In many areas of Siberia, they are more than kilometers deep and are hundreds of thousands of years old. These permanent frosts have started melting due to the increase in the average temperature in the Arctic. Due to this, the bacteria of the soil have started fissioning the organic matter stored in them, due to which methane starts releasing and it increases the number of greenhouse gases in the atmosphere, this has created a cyclical mechanism of climate change.
The Arctic is warming three times
Experts warn that by the year 2100 if CO2 emissions are not controlled, permanent frosts could cause massive thawing. From 1971 to 2019, where the average temperature of the Arctic has increased by 3.1 degrees, the world’s temperature has risen by one degree. There is also the fear that permanent frosts may reach a point where return may be difficult.
Researchers say that we have activated a system that will continue to emit carbon for hundreds of years. All this is affecting about 4 million people here in the entire Arctic. New ponds and lakes can be formed here, new ways of water flow have been seen. And many areas can dry up completely. The biggest of this will be that the effect will be trouble in achieving the goals of the Paris Agreement.
