1 . Lapland's reindeer (驯鹿) grow well in winters of -30℃ and even colder. So when rain falls instead of snow during the coldest months in the Arctic,it makes food hard to get for them. Now one of the best-loved symbols of Christmas is probably dying out. Numbers have fallen by over half in the last two decades as the place warms at four times the global average rate.

The animals are used to pull sleigh (雪橇) rides for tourists. The rides are part of Lapland winter wonderland experiences in thousands of British tourists each year. But this year the working herd had to be moved 60 miles further north due to the absence of snow. As a result, they can't be provided in some areas, making it hard for people to earn a living.

Lapland is often described as Europe's last great wilderness, home to lynxes, brown bears, wolverines and golden eagles. Tourism is a big part of the economy, and the town of Rovaniemi is also the "official home of Santa Claus". But changing climate (气候) is threatening its tourism industry. A report by The Finnish Climate Change Panel warns of flooding and increased rainfall, with Rovaniemi most at risk. Firms that rely on snow "will have great effects on visit levels" and these industries may be forced further north.

Erkkila of the Arctic Husky Park in Rovaniemi says: "Tourists see pictures of the Santa Claus village covered in snow and when they get here they think, 'Is this the winter wonderland?'." The Husky Park bought a wheeled cart (车) six years ago as a replacement for sleigh rides when the snow fails.

In the past it was thought the Arctic was warming twice as fast as the rest of the world. But a report published last week by scientists showed the rate is actually four times the global average.
