Significant Heat Returning to Siberia This Week
20 July, 2020
The heat blast in Siberia continues in 2020. This week, temperatures of 30-34 C (86-93 F) will impact parts of northern Siberia, including close to the shores of the Laptev Sea and the East Siberian Sea.
Monday will be abnormally warm close to the Arctic Ocean, but the hot weather will come farther north Tuesday-Saturday (at least). The following are forecast air temperature maps from the American Global Forecast System model.
The heat in the Arctic continues to do a punishing number on sea ice (and create a feedback loop with warming, dark, exposed ocean), with plummeting Arctic sea ice extent and well-above normal sea surface temperatures in the Siberian Arctic seas.
Earlier this week, research conducted by World Weather Attribution suggests that the extreme Siberian heat that has occurred between January-June 2020 was almost impossible without anthropogenic (human-induced) climate change. The very abnormal heat in Siberia has been 4-7.5 C above normal (1981-2010 climatology), including a high of 38 C/100.4 F in Verkhoyansk, Russia (located at 67.55 N), possibly the hottest temperature ever recorded north of the Arctic Circle.

This combination image illustrates the speed at which Arctic sea ice is disappearing, with sea ice thickness shown in meters from left to right at June 1, June 18, July 1 and July 18, 2020.
This is what alarms me.
The Arctic sea ice extent is pretty alarming but it is the sea ice thickness that
frightens me most. Ice is getting pretty thin and we have only that small sliver
of green (that does not include the North Pole) left of ice that is up to 2 metres
All the rest (the purple and the blue) could disappear quickly in these
conditions while also being exposed to warming seas from below. A heatwave
is going to affect the Arctic for the next few days.
