The hot winds that 2016 brought us were the main reason that large blocks of ice started to melt in the Arctic ocean, which as a reaction caused even bigger ice separation from the main body so to speak.
In December 2015 a cyclone of war air from the North Atlantic ”had cleared” parts of the northern region. Because of the temperatures which were 10 degrees higher than normal in just 10 days a noticeable ice in the size of Florida disappeared.
Regarding this NASA publisher a report, the same day that the UN released figures showing that 2016 was the warmest year in history. The unusual hot storm happened in the period when the ice in the regions is generally collected and tightened, and simply does not melt…. but nature is a force 🙂
As a result of the cyclone, the amount of ice in the Barents and Kara Sea has been reduced by whooping 10 percent, and the edge of the ice has been moved a bit to the north.
In that storm the experts concluded that even the thinnest ice has been completely melted. In the years that follow, if the winter starts with thinner ice, the melting can be much larger.
Here is a fun and education video focusing on Warm winter cyclone:
It is worth to mention that in some regions of the Russian Arctic the temperatures were 6 to 7 degrees above average. Many other arctic, subarctic regions of Russia, Alaska and northwest Canada were at least 3 degrees above average.
