Henry Pollack

Henry Pollack brings a geophysicist’s perspective to climate writing, drawing on decades of research into Earth’s temperature history. A World Without Ice explains how glaciers, sea ice, permafrost, and polar systems influence water supplies, coastlines, habitats, and human settlement. Avery published the general-interest book, which includes a foreword by Al Gore. Pollack is a University of Michigan professor emeritus of geophysics and contributed to the Intergovernmental Panel on Climate Change assessment recognized when the organization shared the 2007 Nobel Peace Prize. His earlier book Uncertain Science...Uncertain World examined how scientific uncertainty is understood. Both works reflect his emphasis on explaining complex evidence clearly to non-specialist readers.
