In 1658, a Swedish army marched across the Great Belt to Denmark to attack Copenhagen.The winter of 1794–1795 was particularly harsh: the French invasion army under Pichegru was able to march on the frozen rivers of the Netherlands, and the Dutch fleet was fixed in the ice in Den Helder harbour.The major differences between the various proxy reconstructions relate to the magnitude of past cool excursions, principally during the twelfth to fourteenth, seventeenth and nineteenth centuries." but a series of events before the known climatic minima has often been referenced.In the 13th century, pack ice began advancing southwards in the North Atlantic, as did glaciers in Greenland.The result is a picture of relatively cool conditions in the seventeenth and early nineteenth centuries and warmth in the eleventh and early fifteenth centuries, but the warmest conditions are apparent in the twentieth century.Given that the confidence levels surrounding all of the reconstructions are wide, virtually all reconstructions are effectively encompassed within the uncertainty previously indicated in the TAR.
The Intergovernmental Panel on Climate Change Third Assessment Report considered the timing and areas affected by the Little Ice Age suggested largely-independent regional climate changes rather than a globally-synchronous increased glaciation.
The Norse colonies in Greenland starved and vanished by the early 15th century, as crops failed and livestock could not be maintained through increasingly harsh winters, but Jared Diamond has suggested they had exceeded the agricultural carrying capacity before then.
Greenland was largely cut off by ice from 1410 to the 1720s.
Fireplace hoods were installed to make more efficient use of fires for indoor heating, and enclosed stoves were developed, with early versions often covered with ceramic tiles.
The Little Ice Age, by anthropology professor Brian Fagan of the University of California at Santa Barbara, tells of the plight of European peasants during the 1300 to 1850 chill: famines, hypothermia, bread riots and the rise of despotic leaders brutalizing an increasingly dispirited peasantry.
