The past weekend in the Arctic was really hot – or rather “hot”. Although we are talking about temperatures around zero or slightly above, these were the indications significantly exceeding the norm. On Saturday, February 1, average temperature North of the Norwegian archipelago Svalbard was 18 degrees higher than the many years of average (from 1991-2020). In the ny-alesund settlement (it is such a “scientific town”) at Spitsbergen (also Svalbard) all night from Saturday to Sunday the temperature did not drop below +2.3 degrees Celsius. This The highest minimum temperature for Februarysince when measurements are carried out, i.e. from 1974.

Disturbing weather in the Arctic

On Sunday, temperature anomaly in the area North pole It was already 20 degrees. And on Monday, February 3, there were even five degrees Celsius on Svalbard. Above zero was also on the land of Franciszek Józef (this is a Russian archipelago) – it happened there in February for the first time in history.

This extraordinary heat was associated with a deep low pressure system over Iceland, from where the masses of warm air moved towards the North Pole. This was supported by the extremely warm waters of the North-Eastern Atlantic. “This type of event is relatively rare, but we are not able to assess its frequencies without further analysis,” he said The Guardian daily Julien Nicolas from Copernicus Climate Change Service, EU climate change service. A similar weather anomaly occurred in February 2018.

Less ice on the water, smaller albedo

The arctic is warming at a rate four times faster than our planet as a whole. This can be seen, among others, in the decreasing surface of sea ice. In December it was record small, almost record -breaking in January (on average 13.13 million km2). No wonder, in a large part of the area of ​​the January Arctic, air temperatures were higher than the many years of norm, especially north of Greenland and over Central Alaska.

The melting of sea ice is particularly important in the far north of Earth. White ice reflects solar radiation well (it has high albedo). When it is not there, dark sea waters are absorbed, which promotes insulation. This also has other consequences. Less sea ice is water more open to sailing. This is, among others, an arctic, and recently mainly Greenlandbecomes a region in which world powers are increasingly directing sight – and military forces.
