Almost 200 years ago the Northeast endured a dramatic, devastating series of cold spells, destroying crops, forcing thousand to migrate west, and causing many to wonder if their assumptions about a world governed by a beneficial Providence were valid. The so-called \"year without a summer\" also exposed weaknesses in political and theological authorities, spurring a trend toward scientific inquiry and greater democracy. An endangered New England agriculture gave impetus to that region\'s manufacturing sector. The alarming threat to existence in that part of the country (as well as most of Western Europe) thus helped usher in the modern era. This book is written with the parallels between 1816 and our current \"climate change\" in mind: it introduces informed non-specialists to the myriad of social, psychological, political, demographic, and economic consequences which can be brought about by abrupt climate change.
