Well Bob, simple search:  In the years 2007, 2008, and 2009, Al Gore made statements about the possibility of a complete lack of summer sea ice in the Arctic by as early as 2013. While Gore attributed these predictions to scientists, they stemmed from a selective reading of aggressive estimates regarding future melting.

Two things:  He did in fact incite many emotional people with his 'erroneous' statements, utilizing his bully pulpit to make a lot of money for himself.  Secondly, the so called scientific predictions were selectively picked to incite fear and based on "aggressive estimates", some of which have been shown to be manipulated!
