<p>In 1992, Resources for the Future conducted a workshop concerning the issues of global climate change. This title, originally published in 1993, is a collection of the revised versions of the papers commissioned for the workshop with an added introduction and overview. Each paper emphasises the potential nonlinearities or surprises in physical effects caused by humans loading the atmosphere with greenhouse gases and examines how shifts in the natural environment from climate change may affect human well-being. This collection is a valuable resource for any student interested in environmental studies and climate change issues. </p>
