A new research states that the Arctic region has once again set a new record of rising temperatures, which is also lowering the ice cover this season. This is the third time this season since November 2016 that the region is experiencing such high temperatures.

“If you look at where sea-ice extent is right now, we’re at a record low, compared to the remainder of the satellite record that goes back to 1979,” said Mark Serreze, a senior research scientist at Snow and Ice Data Center in Colorado. He and his team reported that the Antarctic sea-ice cover in January this year was just above 5 million square miles. The number is a whole 100,000 square miles than what is was in January last year and is half a million square miles less than the average for January for the past 38 years.

The researchers also confirmed that the temperature rise was witnessed especially in the Arctic regions located above 80 degrees north latitude. The temperature in those regions was about 20-degree Celsius, or 68-degree Fahrenheit, higher than the average temperature during that time of the year.

As per the scientists, the reason for this adverse effect is the interactions between warm air and sea ice in the region, besides climate change. Serreze said that a low-pressure storm system that carries warm air towards the north may be responsible for the decreased sea ice, and it may be just because of the normal climate variations.

However, the team also suspects the loss of sea ice is driving the storm. They call it the “chicken-egg thing”. The Arctic has less ice because it’s warm, and it’s warm in the Arctic because there’s less ice.
