Sarah Dry delves into the 150 year effort to understand the world’s climate systems in her book Waters of the World. 

The book is a collection of six mini biographies of the scientists who uncovered the global climate systems by studying water – from ice sheets and glaciers, to surging ocean currents to rainclouds.   They came to see these as all part of a global system together with the combined impact of humans.
