In 1854 New York, Eunice fights to be recognized for a trailblazing environmental discovery. In near-future London, Clare begins an irresistible flirtation with a coworker at her climate nonprofit. In 2100 Svalbard, Ana tries to grow seeds (and a baby) while a months-long storm rages outside her lab. With wild inventiveness and humor, this “elegant and exciting” play “shrewdly questions how we can actively cultivate hope, even as we feel overwhelmed by despair” (The Stage) — confronting our time’s greatest challenge with a dazzling intellect and a beating human heart.
