2014: The Year Without Summer

From global warming to extreme weather

In their excellent book, The Year Without Summer: 1816 and the Volcano That Darkened the World and Changed History, William and Nicholas Klingaman relate the history, causes, and effects of the record cold that gripped the northern hemisphere in 1816.  For most in America, Europe, and Asia, the winter of 1815-1816 was the coldest in living memory.  What followed in the spring and summer of that year was equally disastrous.  It was an entire year of cold rains, crop failures, hunger, and economic collapse.

There were multiple causes for the extreme weather of 1816, but all of them were natural, not man-made.  Chief among them, according to the Klingamans, was the massive eruption of Tamboro in present-day Indonesia.  The force of the explosion was ten times greater than that of Krakatoa, which took place in 1883.  Heightened volcanic activity sent ash particles into the atmosphere, blocking sunlight and disrupting the northern hemispheric jet stream.  One after another, polar vortexes dropped south, not just in the winter, but throughout 1816, and to a lesser extent for years afterward.

The winter of 2013-14 bears a striking resemblance to that of 1815-16, and there is every reason to believe that what follows will repeat the pattern of earlier periods of extreme cold.  The consequences will not be pleasant.  As some have begun to realize, periods of extreme cold are far more destructive than periods of warming.

My prediction of a “year without summer” is based partly on the record of 1816 and other years of increased volcanic activity.  Like 1815, 2013 saw significant volcanic activity, with major eruptions in Indonesia, Alaska, Italy, Argentina, and Japan.  It was inevitable that this "particularly eventful year" of volcanic activity would be followed by a cold winter, just as it is inevitable that more cold will follow.
