Arctic Glaciers Began to Melt Early

Arctic Glaciers Began to Melt Early

Scientists had expected that the frozen soil layers (glaciers) in Canada’s Arctic region would not deteriorate for the next 70 years. However, recent research surprised. It turns out that these glaciers are already beginning to melt.

According to satellite images obtained in researches, the once frozen surface (arctic glaciers) collapses and replaced by a view similar to a perforated cheddar cheese. Speaking to How it Works magazine, Louise Farquharson, a PhD at the Permafrost Laboratory at the University of Alaska, “We all amazed that the system responded so quickly to temperature change,” says Louise Farquharson. Frozen soil is the name of the soils that have remained frozen for at least two years. Approximately 15 percent of the northern hemisphere is frozen soil. This layer plays a critical role in carbon transfer from living organisms to the atmosphere.

The rising temperatures of summer accelerated the melting due to the lack of vegetation covering the soil. The effects of melting have become visible today. When the top of the soil melts, irregular subsidence begins and the topography of the region changes.

Sooner than anticipated

The former flat lands of the Canadian Arctic are now nothing but pits and small lakes. The area at the far north of the area where the research took place collapsed 90 centimeters throughout the research. The glaciers have visibly melted. “We were able to link the change in air temperature and ground temperature with the change in topography,” says Farquharson. According to the estimation, the melting will affect the global climate and its ecological reflections in the region will be seen in a short time.

Farquharson said, “You can think of frozen lands like a giant freezer. It contains plants and organic substances that have not been decayed by microbes. When it starts to melt, the refrigerator door is opened. Microbes are beginning to turn organic matter into carbon dioxide. When the physical structure of the region changes, the local ecosystem is also affected. “New plants grow, constant feeding cycles are disrupted, sediment from currents begins to accumulate in the area,” he says.

Farquharson and his team stated that; they found that an area of ​​600 thousand square kilometers is in danger of rapid melting.
