Norwegian royals visit Arctic research ship

The Arctic is entering what is being described as "a new era" as temperatures rise and the ice covering the ocean becomes thinner, according to scientists taking part in an expedition run by the Norwegian Polar Institute.

Since the start of the year, the research vessel Lance has been drifting in the ice-pack to give scientists the chance to investigate how this region is changing.

The BBC's science editor David Shukman spoke to Norway's Crown Prince Haakon and Crown Princess Mette-Marit, who were visiting the the Lance, to find out their thoughts on climate change.
