moreCNSNews.com) - A critic of "global warming alarmism" began filming a documentary Thursday that seeks to rebut some of the claims former Vice President Al Gore made in his popular movie, "An Inconvenient Truth."
Steven Hayward, editor of the "Index of Leading Environmental Indicators," began filming "An Inconvenient Truth ... Or Convenient Fiction?" with presentations at the Washington, D.C., headquarters of the conservative Heritage Foundation.
Hayward, who is a fellow at the Pacific Research Institute and the American Enterprise Institute, said he hopes to counter some of the "alarmist" claims that supporters of global warming catastrophe theories make.
He began his 40-minute presentation by extending an olive branch to Gore, saying that "much of what Vice President Gore says about climate change is correct. The planet is warming; human beings are playing a substantial role in that warming."
But, Hayward quickly added, "The vice president and a lot of other people make some extreme claims about what is likely to happen in the future that are not backed up by science."
He 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 also criticized global warming "alarmists" for trying to close debate on the issue.
The centerpiece of his documentary, like Gore's, will be the presentation of a slide show on climate change science. But where Gore's presentation gives evidence that shows a consensus on the severity of global warming, Hayward's theme is that there is no consensus.
There is no consensus on the effect human beings have on global warming, versus the effects of other factors such as the sun, Hayward says in his presentation.
There is also no consensus on the status of ice caps and glaciers, he argues, noting that some scientists point to receding or melting ice in western Antarctica while others point to thickening ice in eastern Antarctica.
