Kolyma highway in Yakutia, also known as the Road of Bones, is on fire and temporarily shut

More than 2,000 people are deployed in extinguishing wildfires raging around Russia’s coldest inhabited territory, Yakutia, now in the third year of extremely intense season of wildfires.

The first of them ignited as early as the beginning of May right outside the world-famous Pole of Cold, the village of Oymyakon in northeastern Yakutia known for its record low temperatures.

Wildfires continued through May and June, with extra fire extinguishing forces needing to be sent from other regions to help republic’s own teams.

Today Kolyma highway, the major road connecting republic’s capital Yakutsk and the port town of Magadan on the Sea of Okhotsk, had to be shut because the fire got too close to the road and was much too fierce for safe driving.

After looking at the heat and subsequent fires in the Pacific Northwest, I looked through Nullschool's Earth viewer for other areas under peril.

The Yakutia region of Siberia is under a staggering amount of wildfire. The fires seem to have been burning since May, though by both particulate and CO channels at Nullschool, have exploded in size and intensity in just the past 48 hours or so (that would be after the dateline of this article).

Several videos on the article show conditions on the ground.

A snapshot of current conditions as noted by Nullschool:

Particulate channel, shows the location generally of smoke. I've selected the PM1 rather than PM2.5 channel as the latter is somewhat noisier, though it's generally what's used for smoke tracking. Both are fine particulate matter.

CO channel, where carbon monoxide is a much more specific indication of where there is current combustion. These signal regions themselves are immense. My eyeball estimate is that this is roughly the size of the state of Oregon.

Ancient DNA Analysis Sheds New Light on Occupational History of Denisova Cave

In a new study published this week in the journal Nature, an international team of researchers analyzed DNA from more than 700 sediment samples that were collected from the Pleistocene layers of Denisova Cave in Siberia and detected ancient hominin and mammalian mitochondrial DNA (mtDNA) in 685 and 175 samples, respectively; the earliest evidence for hominin mtDNA is of Denisovans, and is associated with the stone tools that were deposited approximately 250,000 to 170,000 years ago; Neanderthal mtDNA first appears towards the end of this period; the authors also detected a turnover in the mtDNA of Denisovans that coincides with changes in the composition of faunal mtDNA, and evidence that Denisovans and Neanderthals occupied the site repeatedly — possibly until, or after, the onset of the Initial Upper Paleolithic at least 45,000 years ago, when modern human mtDNA is first recorded in the sediments.
