Environmental history especially, and increasingly all of history, is becoming more attuned to exploring pasts defined not only by words, texts, and human artifacts but also by patterns of nature, be it rusting industrial ruins, solar flares, or microbial epidemics. In the current postatomic, post-COVID era where historians and audiences have become more deeply attuned to the power of historic ecological and material “feedback loops” having different sorts of agency with different half-lives extending into the future, more historians now work to incorporate various “archives” of natural and natural-material events as detailed via statistics, photographs, and other media into their books and exhibits to challenge audiences to imagine more-than-human life histories and to evaluate such events as wars and histories of colonialism, development and trade through various green or multi-lifeform lenses. In these two panels based on a forthcoming forum in the American Historical Review’s History Lab, contributors draw from various nontextual sources in their research to find new ways to “read nature” into history and to visualize worlds—real and imagined—that range from gene flows and built and natural landscapes to the solar system and the cosmos.
