Tambora in April 1815, which ejected a cloud of sulfur dioxide into the upper atmosphere, plunged the world into a rapid temporary climate change event. A series of bizarre weather anomalies, including snowstorms in June and repeated heavy frosts throughout the rest of the summer, earned 1816 the moniker “the Year Without a Summer.” This paper examines the various ways in which Americans reacted to the climate change—seeking causation explanations through science and superstition, political and religious responses, and the efforts to ap- preciate what the events meant in terms of the world’s changing climate. Through these various reactions, a picture emerges of Americans’ incomplete understanding of science and nature, as well as an uneasy reckoning with the impossibility of fully explaining their environment and the potential dangers it presented to them. iv CURRICULUM VITAE NAME OF AUTHOR: Michael Sean Munger GRADUATE AND UNDERGRADUATE SCHOOLS ATTENDED: University of Oregon, Eugene, Oregon Tulane Law School, New Orleans, Louisiana University of New Mexico, Albuquerque, New Mexico DEGREES AWARDED: Master of Science, History, 2012, University of Oregon Juris Doctor, 1998, Tulane Law School Bachelor of Arts, History, 1993, University of New Mexico AREAS OF SPECIAL INTEREST: United States History—Early Republic Environmental History PROFESSIONAL EXPERIENCE: Teaching assistant, Department of History, University of Oregon, Eugene, 2010-2012 Attorney, Schwabe, Williamson & Wyatt P.C., Portland, Oregon, 2006-2009 Attorney, Law Practice of Sean Munger, Beaverton, Oregon, 2004-2006 Attorney, Tonkon Torp L.L.P., Portland, Oregon, 1998-2004 GRANTS, AWARDS, AND HONORS: Thomas T.

He also described the Fourth of July celebrations in Plymouth, Connecticut: “I saw several men pitching quoits in the middle of the day with thick overcoats on, and the sun shining bright at the same time. A body could not feel very patriotic in such weather.”1 Jerome’s book was primarily a history of the American clock business. Yet the weather anomalies of a summer long past found their way into his memoirs; they were obviously on his mind until nearly the end of his life. He died in 1868. A decade later, another memoir-writer similarly remembered the cold summer of 1816. Sarah Anna Emery, then a young New Hampshire woman, looked back on it in 1879, when she was in her nineties. She recalled Thursday, June 6, the day before the snow squall that Chauncey Jerome remembered. On a trip with relatives to Boscawen, New Hampshire, Emery and her party paused to attend the inauguration of Governor William Plumer. “Our teeth chattered in our heads,” she wrote, “and our feet and hands were benumbed...even
