Did the authors take the expansion of Norwegian glaciers into account? There's a glacier arm in Norway named after the farm it swallowed during the Little Ice Age: http://en.wikipedia.org/wiki/Nigardsbreen#History http://en.wikipedia.org/wiki/Nigardsbreen#History > Between 1700 and 1748, the glacier moved forward about 4 kilometres (2.5 mi) completely covering and crushing the "Nigard" farm (hence the name of the glacier). By 1748, the Nigardsbreen covered about 48 square kilometres (19 sq mi). From 1930 until 1939, the glacier retracted again.
