So far, this year's summer may not give associations to climate change, but for the past 30 years, summer has actually been a full 12 days longer in Oslo.

March becomes the hundredth month in a row with temperatures above normal. "It is unique and shows how fast climate change is happening in the Arctic," says climate scientist Ketil Isaksen at the Meteorological Institute (MET).

It was hotter today on Svalbard than in the Norwegian capital, Oslo. So much so, that the previous temperature record from 1979 was smashed.

At Longyearbyen airport, the peak temperature reached 9.2 °C for a short period, nearly two degrees warmer than the last November record measured in 1975.
