Dr. Richard Alley – Geologist & Climate Change Specialist: It is no longer a matter of if, how or how long…it’s real & it’s happening.  The amount of greenhouse gasses within Earth’s atmosphere are increasing at an alarming rate which is causing a continuous and unsustainable rise in the Earth’s climate. This is not alarmist, I’m not preaching, it’s just true.  When Al Gore released released the documentary, “An Inconvenient Truth” it was a wake up call for many and we began to realize the effect that our industrialization, specifically regarding our food supply, is having on our world. So what exactly is happening? How do we KNOW about global warming? And most importantly, what can we do about it?

Funny you should ask, it just so happens these are the exact questions we answer this week when we interview American geologist and Evan Pugh Professor of Geosciences at the Pennsylvania State University, Dr. Richard Alley.  He has authored more than 170 refereed scientific publications and is recognized by the Institute for Scientific Information as a “highly cited researcher.” AND, Dr. Alley was a contributor to the United Nations Intergovernmental Panel on Climate Change, which shared the 2007 Nobel Prize with Al Gore so add a Nobel Laureat to the SPP resume!
