A critic of what he calls "global warming alarmism" says extreme claims made by former Vice President Al Gore and others about what is likely to happen in the future that are not backed up by science.

"The world has warmed over the last century. There's reason to think we will warm further, however, there's lots of very good reason for thinking that the warming we are likely to experience in this century is going to be very modest," said Steven Hayward with the Pacific Research Institute.

Hayward said Gore's predictions that global warming will lead to more intense hurricanes, flooded coastlines and demolished cities are based on extreme and improbable models.

Hayward's new documentary on DVD "An Inconvenient Truth ... Or Convenient Fiction?" challenges Al Gore's global warming claims made in his popular movie, "An Inconvenient Truth."

"It's me giving my presentation to a live audience like he did of my take on the whole climate change issue. It's shorter than Vice President Gore's movie, because I think I talk a little faster than him and I have less about me running for president in it, since I never did that," Hayward said.

Hayward said much of what Gore said about climate change is correct. The planet is warming; human beings are playing a substantial role in that warming. But, Hayward adds, extreme claims about what is likely to happen in the future are not backed up by science.
