While a rise of two degrees on a household thermostat would be scarcely noticeable, climate scientists have warned that the same amount of warming measured on a global scale would be disastrous. Contemporary playwright Tira Palmquist’s latest work, Two Degrees, follows the efforts of Emma Phelps, a dedicated paleoclimatologist who ventures to Washington, D.C. in an effort to oppose measures that would further erode the environment. Without shying away from the disturbing scientific evidence, the timely drama recognizes that policymaking is an endeavor wrought with human folly, having as much to do with career ambitions as public wellbeing. The standout cast includes Norah Long as Emma, with a supporting cast of Jennifer Whitlock, Toussaint Morrison, and Joel Liestman. This Shelli Place-directed staging marks the second season for Prime Productions, an organization committed to cultivating roles for women over 50.
