"Al knows his stuff but he's got a lot of baggage associated with it. People remember back in 1988 when [former President George H.W.] Bush called him ozone man. People remember this and think he's got an agenda. Coming from Hillary, it sounds fresher," Gelbspan said.
So is all this talk about global warming a reality? Could something really be done in a president's term? Or is this concern just political positioning to get back in the big white house?
Realistically, Gelbspan said one president could have a real impact on the environment.
"There needs to be a focus on making a global transition to clean energy," he said. "Domestically, we spend $25 [billion] to $30 billion in subsidizing oil, coal and fossil fuels. We need to put that money into renewable energy and focus in on developing countries."
It doesn't really matter how interesting Gore's powerpoint presentation is or if Hillary really cares about global warming, Gelbspan said. What matters most is that people's level of awareness on the environment is increasing.
