The town is Verhoyansk for those who don't want to click a forbes article.

I feel this is clickbait (at least the title). Continental climates fluctuate a lot. One day breaking a record could simple be a statistical outlier. A poke around the records does show that the entirety of June so far has been well above average, and that this is not normal. But I guess "global warming slowly driving more extreme high temperatures in artic siberia" doesn't get as many clicks.
