Already before noon on Saturday, Norway’s Meteorological Institute reported the temperature in Longyearbyen to be 20 degrees Celsius. Before 1 pm, the temperature reached 20,6°C and by early evening, the heat peaked at 21,7°C, a tweet update from @Meteorologene says.
This is the first time since 1979 the official temperature in the main settlement on Svalbard is above 20°C, the institute tells. On July 15, 41 years ago, the temperature reached 21,3°C.
Located at 78° North, Longyearbyen faces climate changes like few other towns. Houses are sagging as thawing permafrost makes the ground unstable. Until last winter, Svalbard counted 100 consecutive months with above normal temperatures.
Some periods have seen 12-14 degrees over normal around Longyearbyen.
The meteorological institute explains the heat with the negative spiral caused by climate change. Less sea-ice and less white snow-covered land mean less of the sunlight being reflected back to space. Darker waters-surface and soil absorbs more heat, again accelerating the permafrost thaw and causes more sea-ice to melt.
If global emissions continue to increase like today, the annual average temperature at Svalbard will be above zero degrees by the end of this century, the meteorological institute predicts.ADVERTISEMENT
