European winter warmest since Middle Ages

According to New Scientist website, last year's exceptional European winter was the warmest since 1289, when unusual temperatures were caused by a large volcanic eruption in the tropics.

The freak winter is Europe's warmest for 700 years. The last time this happened, personal diaries recorded that Europeans ate strawberries at Christmas, and vineyards produced grapes in January. Scientists are reluctant to pinpoint climate change as the cause, but they continue to study the freak winter.
