Global warming debate creates divide among scientists

Former Vice President Al Gore's name has become synonymous with global warming.  Gore pressured the public, saying people are solely responsible for global warming, and created a "go green" mania.

However, Gore's movie, The Inconvenient Truth, has much opposition that the public may not know.  Ian Plumber of Adelaide University says climate data has been massaged, and there is complete obstruction.

"Because you get one upward trend recently, will mislead a lot of people," another well-known scientist, Dr. Bill Gray, said as he noted global warming could be over-hyped.

The earth is warming, but scientists remain divided on the cause.  Gore makes an argument of a positive correlation between hurricanes and tornadoes.

"The same year that we had that spring of big hurricanes," he said. "We also hit an all-time high of number of tornadoes in United States."

Kevin Pence of the National Weather Service agrees that we're seeing more storm reports, but isn't quick to put the charge on global warming.

"We think that has to do with, you know, folks having cameras on their cell phones, video recorders, education," he said.

So are our green efforts even making a positive impact?  The truth is, despite drastic green efforts, carbon dioxide may never go away because it's life cycle can be anywhere from 50 to a thousand years.

"It's not like we can take a vacuum cleaner, turn it on and suck all the greenhouse gases out of the atmosphere and we'd be good to go.  It's not the case," Pence explains.

With only 30 years of satellite data, the convenient truth is there's a lot of research that still needs to be done.
