The climate cost of planting trees

Most people has a good relationship with forests and the uncontrolled logging around the world is taking its toll on both the wildlife, but also the climate. It stand to reason that letting the forests grow and claim land should be unconditionally positive for the planet, but as often it is not so simple. Priscilla Mooney, a researcher at NORCE and the Bjerknes centre, talks to our host Stephen Outten and co-host and producer Ingjald Pilskog about the consequences of both the destruction of the forests and the unexpected costs of letting the forests claim the higher latitudes and planting new forests without a proper understanding of the effects.
