Gale E. Christianson 
Greenhouse 

For historian Gale Christianson, the emergence of global warming is one of the most compelling stories in the history of humankind, made all the richer for having been a slowly developing phenomenon. In his brilliantly constructed book Greenhouse, Christianson blends the research of a scholar with a novelists storytelling skill, offering an invaluable perspective on what may be the most remarkable change in nature since the retreat of the glaciers some 10, 000 years ago. Like a train coming at you from a distance, global warming is first a faint, echo-ing whistle, then a puff of smoke, and ulti-mately, with a rush, an unavoidable reality. Finding the clues to global warming both deep in the past and right before our eyes, Christianson introduces a memorable and unlikely cast of characters and events. From the demise of the Anasazi in the American Southwest and the Vikings in Greenland, which unveil the close connection between global warming and cooling, to the politics behind the 1997 Kyoto Conference on the Environment, Christianson delves deep into the connection between human beings and the planet.
