Skiers walk in a snowless landscape on January 2, 2017 in the Swiss Alps resort of les Crosets.
Switzerland has just experienced its driest December in more than 150 years and one of its driest months on record, meteorologists said. Many places in the west of the country did not see a single snowflake or drop of rain, it said, pointing out that usually the Swiss plains get nearly 90 millimetres of precipitation on average in December. / AFP PHOTO / Nicolas ASFOURI        (Photo credit should read NICOLAS ASFOURI/AFP/Getty Images)
