What is the northernmost human settlement with year round inhabitants?

The northernmost human settlement with year-round inhabitants is Alert, located in Canada. It is situated on the northern tip of Ellesmere Island, at a latitude of 82.5°N. Alert is a scientific research station and military signals intelligence site. Its remoteness and harsh Arctic climate make it challenging to sustain life, but a small population manages to survive year-round, mainly comprising weather observers, military personnel, and scientists. As the weather station provides crucial meteorological data for weather forecasts and climate studies, the strategic location of Alert enables continuous observation and evaluation of the Arctic region.
