Clean energy can't come at the expense of the ocean – and it doesn't have to

27.07.2020

As clean energy expands, demand for metals and rare earth elements is growing along with it. Developing the wind turbines, solar panels and batteries that will power our low-carbon future requires cobalt, nickel, zinc, copper, silver, gold, lithium and more.

The “refrigerator effect” of the Barents Sea is weakening

25.05.2020

The water entering the Barents Sea is not as cooled down as it used to. This has a large effect of the climate in the area and may lead to fish and other marine life migrating.

Cod and haddock populations have multiplied over past 20 years

01.04.2020

In the 2000s, the Norwegian and Russian authorities reduced the fishing pressure on cod and haddock in the Barents Sea. Combined with three good year-classes, that led to record populations.
