A temperature of 38 degrees was measured on the Arctic Circle last Saturday, BBC News writes Monday. The area has to deal with a heat wave.

These are the first measurements that still have to be checked. But if it is correct, then there is a good record. The temperature would then be 18 degrees higher than the average maximum temperature in June.

The record was measured at the Siberian place Verkhoyansk - usually one of the coldest places on earth - with about 1,300 inhabitants. The ground is always frozen there, a phenomenon called permafrost.

The area normally also experiences extreme temperature fluctuations. In January it does not get warmer than -42 degrees, while in June the mercury rises to an average of 20 degrees. This is partly due to an exchange of air flows: in the summer warm air flows to the north and cold polar air to the south.

Heat waves are no stranger to the region either. However, temperatures have been particularly high in recent months. For example, in the Arctic Circle in May it was about 10 degrees warmer than average for a month, according to Copernicus's climate change service.

Increasingly warm at the Arctic Circle

The record temperatures initially seem to be mainly the result of a high-pressure area that has been hanging over eastern Russia for several months.

However, temperatures have become increasingly frequent and persistently high in recent decades. This development fits in with the fate that, according to scientists, the region is facing due to climate change.

Most scientists agree that the Arctic has warmed twice as fast as the world as a whole in the past thirty years. The melting ice, among other things, contributed to this.

That white ice reflects sunlight, so that the earth and the sea warm up less quickly. As that ice disappears, that effect is lost and a vicious circle is created.

There are also concerns about the natural CO2 and methane reserves that are still stored in the ground, but are released when the ground is no longer permanently frozen. In turn, these greenhouse gases will accelerate the climate change process.
