The northern tree line roughly follows that July isotherm, and the warming climate is pushing the line, and the Arctic itself, poleward.

What is the approximate coldest temperature ever recorded in the Arctic?

Average winter lows reach −40 °C. Most of the region gets under 50 cm of precipitation a year; wind-blown snow just makes it look like it is always snowing.
