How a warm ocean current creates fruit orchards in the Arctic

In short: Norway is often defined by its icy extremes, yet it hosts fertile paradises where fruit thrives north of the Arctic Circle. This geographical paradox is driven by a powerful ocean current that creates mild microclimates, allowing life to flourish against the backdrop of dramatic, glacier-carved cliffs.

The Norwegian landscape is defined by fjords, which are long, deep inlets of the sea formed by the submergence of glaciated valleys. In the west, the Geirangerfjord and Nærøyfjord serve as the world's "type locality" for this geological phenomenon. These fjords are characterized by steep, crystalline rock walls that can rise up to 1,400 meters directly from the Norwegian Sea, with some sections extending 500 meters below sea level. These specific inlets vary in breadth from 250 meters to 2.5 kilometers wide. A gap of 120 kilometres lies between the two bodies of water. The area is notable for its numerous waterfalls and free-flowing rivers.

While the region is known for its ruggedness, the Gulf Stream plays a critical role in its biodiversity. This warm current creates mild microclimates that support fjord-side orchards even in northern latitudes. Such a sharp distinction appears within Norway's scenery: moving from productive, lush regions toward the northern reaches where the Sami folk and their reindeer endure snowy, ancestral lifestyles. This contrast highlights the diversity of the planet's geography. The far north remains a place of snow-bound traditions. The documentary captures these scenes in clear light during perfect weather.

The scale of these landscapes is immense. Spanning 500 kilometres, the west Norwegian fjord scenery extends from Stavanger in the south towards Åndalsnes in the north-east. Within this area, the Geirangerfjord and Nærøyfjord alone cover a serial property of 122,712 hectares. This region is recognized for its outstanding natural beauty, featuring a mix of deciduous and coniferous forests, glacial lakes, and submarine moraines, all complemented by remnants of human history like abandoned transhumant farms. The property includes 10,746 hectares of sea. Marine mammals are also found within these waters. The landscape features rugged mountains and glaciers.
