TROMSO: In the cold of the Norwegian Arctic, meteorologist Trond Robertsen manually recorded precipitation levels for over two decades, witnessing firsthand the effects of climate change.

At 66, Robertsen retired after enduring spartan conditions during missions that totalled eight years on two islands of the Svalbard archipelago: Bjornoya (Bear Island) and Hogen.

To reach the remote Bjornoya, where the only humans are the nine employees of the small weather station, the meteorologists have to fly in by helicopter as they are rotated on a six-month basis.

“The idea is to not stay too long, because it’s a different rhythm, and you are isolated,” Robertsen told AFP.

It is demanding work.
