Temperatures in low soil layers were -4,4°C.Sadly the situation is getting worst. ~Jonas Ferraresso, São Paulo, Brazil pic.twitter.com/2kxrnzGirB
Snip: The city of Yakutsk is shrouded in a grey fog, as though draped in a shawl.
It's the smoke from forest fires we saw from the plane on our way in, spiralling up from the vast expanse of Siberian coniferous forest or taiga.
Our taxi driver advises us to come back in winter.
Minus 50C (-58F) is infinitely preferable to the smoke, he says with confidence.

The climate is continental - plus 30C (86F) in the summer and awash with mosquitoes, then down to minus 70C (-94F) in some parts during the winter. This year the thermometer in the Gorny District of Yakutia hit 39C (102F), with just 2mm of rainfall all month.

Noctilucent clouds are still bright and abundant 2 months after the start of the 2021 northern hemisphere season (May/June - August), and at the highest latitudes they are setting records, Dr. Tony Phillips of SpaceWeather.com noted in his latest NLC update.
"We're seeing more clouds at 80°N than in any other year since AIM was launched [in 2007]," says Cora Randall of the University of Colorado's Laboratory for Atmospheric and Space Research. "Cloud frequencies at 80°N are around 85%, whereas it's more typical to see frequencies of about 75%."
Frequencies' are a measure of patchiness. 100% is complete coverage; 0% is no clouds at all.
