Most people do not have the time or interest required to separate politically motivated news stories from honest science. In The Three Concepts of Climate Change, Bill Goodenough provides you with the results of a six-year study. The first concept of climate change is a summary of the results of climate change studies by the international science community. The second concept of climate change is an assessment of the short-term, limited studies and political pressures resulting in the premature and questionable conclusions conflicting with the first face of climate change. The third concept of climate change identifies a phenomenon that is the most likely cause of today's erratic and changing climate and provides an expanded scope of the excellent science presented in the first face.
