NEW ORLEANS (AP) _ A top hurricane forecaster says former Vice President Al Gore "doesn't know what he's talking about'' in his warnings about global warming.
William Gray calls Gore "a gross alarmist.''
The 77 year old Gray is a professor emeritus at Colorado State University and a highly respected authority on hurricanes. And he has long opposed the theory that heat trapping gases generated by human activity are causing the world to warm.
Gray's comments to The Associate Press Friday came on the same day that an international panel of experts on climate change issued a report that concludes the world will face dire consequences unless nations adapt to climate change.
MIT professor Kerry Emanuel, who has battled with Gray on the issue before, says Gray has wrongly dug in his heels. Emanuel says there's ample evidence of global warming.
Gray delivered the closing speech yesterday at the National Hurricane Conference in New Orleans.
