Dani Inkpen: This book is proof that glaciers can inspire strong feelings of love and attachment, even from far away. Early glaciologists seeking accessible and compelling evidence of global warming had plenty of reasons to turn to repeat glacier photographs. And repeat glacier photographs are generally a pretty good record of landscape change over time. Yet the choices scientists make about what to use as evidence impacts how the phenomenon in question is understood. Visualizations affect how we see the world, making certain aspects visible and rendering others unseen.
