Organisers of an ice sculpture festival in Bruges, Belgium, say higher than average temperatures are causing their energy bills to soar.
Ice Magic's managing director Francis Vandendorpe told Associated Press that the cooling bill would be €10,000 (£7,000, $10,700) more than expected.
Europe has experienced an unusually warm November. The temperature in Bruges will hit 16c (60F) on Sunday.
"People are expecting winter, but they don't get winter", said Mr Vandendorpe.
"The winter is coming later and later" he added.
In order to prevent the ice from melting, the festival is using 12 cooling compressors to chill the hall where the sculptors work.
Several artists have complained of catching colds from frequent changes in temperature as they enter and leave the hall.
