Did anyone hear on the radio yesterday (Jan 3, 2013) a scientist talking about global warming?

He talked about ways to protect the oceans, warming of the planet, etc. and named an organization of grass roots workers. Did anyone hear this interview and/or know the name of the organization? I think the occasion of this talk was an award the scientist was being given, in the name of Steven something. Also, he is writing an easier to understand book on global warming for his grand daughter—Sophie.
I would love to find out more about this man and this grassroots organization. Thanks
