 Coming 
		on stage now is a stunning example of how civilization must rescue 
		itself.  It dwarfs the three big scientific alerts from the 1970s 
		about global warming, ozone loss, and acid rain. But until the 1990s, no 
		one knew much about abrupt climate change, those past occasions 
		when the whole world flipped out of a warm-and-wet climate like today’s 
		into the alternate mode, which is like a worldwide version of the 
		Oklahoma Dust Bowl of the 1930s.  There are big alterations in only 
		3-5 years.  A few centuries later, the drought climate flips back 
		into worldwide warm-and-wet, even more quickly.  Unlike greenhouse 
		warmings, the big flips have happened every few thousand years on 
		average, though the most recent one was back before agriculture in 
		10,000 B.C.  The next flip may arrive sooner than otherwise, thanks 
		to our current warming trend.  The northern extension of the Gulf 
		Stream appears quite vulnerable to global warming in four different 
		ways.  An early warning might be a decline in this current.  
		And according to two oceanographic studies published this last year, 
		this vulnerable ocean current has been dramatically declining for the 
		last 40-50 years, paralleling our global warming and rising CO2.

				The Two Mile Time Machine (Princeton 2000). My human evolution book A Brain for All 
				Seasons devotes the last third to climate influences 
				and to warnings about future abrupt climate shifts.  
				 It is 
				written at approximately the same level (for serious but 
				nonscientific readers) as my Atlantic Monthly cover 
				story, "The great 
				climate flip-flop."    
 
 
    
      
        |  | Is
          the Temperature Rising? The Uncertain Science of Global Warming
          by  S. George Philander  (Paperback ). 
          Written with grace and understatement for general readers, by
          someone deeply involved with modeling the climate, it covers much of a
          Princeton introductory course in the earth sciences. 
          The
          IPCC analysis of where gradual climate change is going, “Climate
          Change 2001: The Scientific Basis,” can be found at http://www.ipcc.ch 
 |  Floods,
      Famines, and Emperors : El Nino and the Fate of Civilizationsby  Brian Fagan.  Paperback (March 2000.) 
      Archaeologists
      have this wonderful perspective on what’s gone wrong in the past, both
      with climate and human institutions.
 
      
        |  | The
          Two-Mile Time Machine by Richard B. Alley (Princeton
          University Press, 2000).  It
          is written for nonspecialists (Alley has gotten a lot of practice as a
          frequent commentator for Science news articles). 
          The book contains far more detail on abrupt climate change than
          the others.  
          So if you find yourself asking, “But how could they possibly
          know that?” you’ll find most of the answers in Alley’s excellent
          book. 
          Its final chapter about the future, alas, is informed by
          conventional economic extrapolation rather than by the more relevant
          perspective of high-risk management seen in medicine, re-insurance,
          and disaster planning.
