Thousands of reindeer go missing in Lapland: BBC

Herders in Lapland are struggling to locate thousands of reindeer that have run away after warm weather left the food they graze on covered by a layer of ice, reported British Broadcasting Corporation (BBC).

Some reindeer have travelled as far as 100km to the south, in search of ice-free lichen they can access under the snow, said the report.

Herders are trying to find out the missing reindeer through the forests of northern Finland and Sweden and in some cases even they are using helicopters.

Scientists say the Arctic is warming twice as fast as the rest of the world as a result of climate change - though new research suggests that could be an underestimate, said the BBC report.

The layer of ice is said to form when an early snowfall melts, or is followed by rain, creating wet snow, which then freezes to a hard layer of ice when temperatures drop, the report added.
