The Debate About Global Warming is Over?

I recently had the privelege of attending a forum where Bob Willard of Sustainability Advantage gave the keynote address.  This is the second time I have had the opportunity to hear Mr. Willard speak and he certainly has gift for simplifying the business case for sustainability.  I have also referenced his books The Sustainability Advantage and The Next Sustainability Wave in many writings.  Along with his ability to simplify and quantify the business of sustainability, Mr. Willard also has a sense of humor. 

One slide in particular caused an eruption of laughter in the audience and may have completely silenced any naysayers on the topic of global warming.  Take a look at this slide and let me know what you think about this approach!  Add your comments below.
