The processes and consequences of climate change are extremely heterogeneous, encompassing many different fields of study. Dr David Rind in his career at the NASA Goddard Institute for Space Studies and as a professor at Columbia University has had the opportunity to explore many of these subjects with colleagues from these diverse disciplines. It was therefore natural for the Lectures in Climate Change series to begin with his colleagues contributing lectures on their specific specialties.This first volume, entitled Our Warming Planet, encompasses topics such as natural and anthropogenic climate forcing, climate modeling, radiation, atmospheric dynamics/storms, hydrology, clouds, the cryosphere, paleoclimate, sea level rise, agriculture, atmosphere chemistry, and climate change education. These lectures each provide snapshots of the cutting-edge work being done to understand what may well be the greatest challenge of our time, presented in a form suitable for classroom presentation.This full-color publication includes lectures with downloadable Power Point slides for students and teachers around the world to be better able to understand various aspects of climate change.
