Alaska had it's hottest ever recorded summer in 2019 [1] and for quite a few years they've been significantly above average.
It's been said the Arctic is the canary in the coalmine for climate change. Once more of the glaciers and permafrost melt more of suns heat energy will be absorbed rather than reflected, and climate change will accelerate.
Of particular worry is accelerated methane release from peat bogs in the thawing permafrost, creating a positive feedback loop (with potentially irreversible consequences) [1] [2].
We’re rapidly running out of runway to mitigate the worst of climate change.
I dread to think how many joules of energy it’s going to take for us to stop emitting carbon, but also sequester that released since the Industrial Age began. I suppose there is some consolation in that enough sunlight hits the Earth in an hour to power humanity for a year, so the clean energy is there for the taking. It’s just going to take decades of sunlight to step back down the carbon curve [3]. Such is the cost of burning ancient sunlight.
I can't find confirmation to this in Russian news, which strongly suggests that this is fake news. If such a record were set, it would beat the +37.3C record set in 1988.
Note that the article says "if verified", which you should read as, "we just published this without verifying".
Don't know about you, but to me the site does not look very credible. Other sources (such as http://www.hmn.ru/index.php?index=8&value=24166) suggest the temperature got up to 36C that day.

https://www.globalforestwatch.org/ is a useful site to get a sense of the size and progression of fires in Siberia.

Here's apparently where everyone is getting this from: http://www.pogodaiklimat.ru/monitor.php?id=24266
