Glacier mega tour bus - 4th November 2020

This gigantic bus ferries sightseers over Langjokull, the second largest glacier in Iceland, on its 8 gargantuan tyres. Measuring 15 metres and dubbed Sleipnir after Odin's eight-legged horse from Norse mythology, the glacier bus zooms across the ice cap at speeds of up to 60 kilometres per hour.

Italian tourist Rosella Greco explains the appeal of visiting the glacier.

Rosella Greco: "It, it feels really emotional and you are, like, touching something that it's so old, and you feel so in contact with the earth. I mean, it's like when you see the Colosseum or something so old."

The glacier has been around for well over two millennia. It rises to 1,450 metres at its highest point. However, rising temperatures are thawing the ice and the glacier's expanse has been reducing each year.

Glaciologist Thorsteinn Thorsteinsson is concerned about Langjokull's future.

Thorsteinn Thorsteinsson: "If this continues in a similar way, or even in a still warmer climate, then it's very likely that all of Langjokull or maybe 80, 90 per cent of it will be gone by the end of this century, really."
