In Big chill in Churchill
(June 13) The National Climate Center's Thomas Karl is quoted as saying: "Such major (weather) oscillations are part of a bumpy road toward global warming." That may be the case, but history shows they are also associated with global cooling.
Between 1250 and 1450, areas from Greenland as far as China experienced a wide variety of extreme weather events. More frequent storms and colder winters forced the Vikings to abandon their agricultural settlements in Greenland, while in Iceland the absence of tree growth forced major changes in architecture and shipbuilding. In Western Europe, the 14th century recorded more cold winters than any other with rivers like the Thames, Rhine and Danube being repeatedly frozen for weeks and months. Cold, snowy winters were often followed by violent spring floods, and heavier-than-normal rains were just as common.
Great North Sea storms drove waters far inland inundating large areas of England, Belgium and Holland; yet hot droughts of unusual severity also prevailed over vast areas.
Further east, high rainfall caused the Caspian Sea to rise to levels much higher than today's, while Chinese documentation shows the 14th century as the only one with numerous records of floods in all seasons. Climate change and weather anomalies appear to go hand-in-glove, and the ones cited above are no exception except they marked the change from the Medieval Warm Period to the Little Ice Age. So maybe, since computer projections are hardly infallible, we're seeing a similar transition from warming to cooling though proponents of anthropogenic climate change theory would hate to admit it.
