A belt of warm air is currently stretching from northern Greenland across the North Pole to the Laptev and East Siberian Seas north of the Russian mainland. Northeast of Svalbard from Franz Josef Land to Severnaya Zemlya see similar heat. On a recent November weekend the average temperature was 6.7°C above normal across the Arctic.
Lancaster city broke two records in the past two days with the "mini November heat wave" that brought unseasonably warm temperatures to the area over the past week.
The Russian archipelago of Severnaya Zemlya saw the largest temperature anomaly on the planet last month. Other surrounding parts of the Arctic were also extraordinarily warm in October. Temperature maps show that practically the whole northern Kara Sea and Laptev Sea was 6 and 8 degrees warmer than normal.
The average high was 52.3 degrees since the beginning of the month in Green Bay, the warmest weather ever. Last year, the average high was 29.7 degrees.
For the first time since records began, the Laptev Sea has not yet formed sea ice by the end of October. Scientists attribute the lack of ice to early summer warming and an extreme heatwave in Siberia, as well as warm Atlantic currents flowing into the Arctic.
The reindeer owners feel they had to choose. Pay expensive fines or move with the reindeer across the river even if the ice was too thin. On Saturday, a thousand reindeer went through the ice in Vuorašjávri, a mile east of Kautokeino municipality in Finnmark.
When glaciologist Jack Kohler returned to Austre Brøggerbreen in Svalbard, he was shocked. More than three meters of the ice at the glacier front had melted away. That's a record. And an ice tunnel had become a trench.
An exceptionally warm air current from the southeast has kept days and nights unseasonably mild in southern and central Finland since last week. Meanwhile the north of the country has been shivering with rain and temperatures in the single digits. The highest reading in decades was recorded in Kokemäki, southwest Finland.
The thermometer at the main visitor centre in Þingvellir National Park went all the way down to –9.6°C last night and meteorologists confirm that is one of the coldest temperatures ever recorded in a built-up area at this time of year—and could even have been a new record.
The multinational company that operates the Red Dog Mine in Northwest Alaska says that thawing permafrost linked to global warming has forced it to spend nearly $20 million to manage its water storage and discharge.
It was out of habit that Rachel Kukull carried foraging tools while hiking through Chilkat State Park. The custom paid off when she spotted on the forest floor a flash of gold that made her scream. Chanterelles in November!
