This book focuses on the application of space technology as a means of potentially solving pollution problems. Remote sensing technology and the tremendous contemporary expansion of multilateral environmental treaties grew out of separate but parallel developments in the 1960's and 1970's. As a tool to improve environmental co-operation, remote sensing has great promise. Just as remotely sensed images raised awareness of ozone depletion, images of receding glaciers and polar ice caps may also have a similar effect on the public's awareness of global warning and its willingness to accept stricter measures that would limit greenhouse gas emissions.
