It turns out Al Gore was wrong. The scientists aren’t all in agreement on global warming; thus there is no “consensus.”
Prominent hurricane forecaster Dr. William M. Gray, a professor at Colorado State University, told the audience at the 2008 International Conference on Climate Change on March 4  in New York that a natural cycle of ocean water temperatures related to the salinity (the amount of salt) in ocean water was responsible for some global warming that has taken place. However, he said that same cycle means a period of cooling would begin within 10 years.
“We should begin to see cooling coming on,” Gray said. “I’m willing to make a big financial bet on it. In 10 years, I expect the globe to be somewhat cooler than it is now, because this ocean effect will dominate over the human-induced CO2 effect and I believe the solar effect and the land-use effect. I think this is likely bigger.”
Gray, 79, wasn’t sure if he’d be around to see his prediction come true.
“I may not be around by that time,” Gray said. “But, I’ve asked some of my students to put dandelions on my grave if that happens.”
Gray criticized NASA scientist and global warming alarmist James Hansen, calling him “the most egregious abuser” of data. According to Gray, Hansen’s alarmism is exaggerated because the models he uses to predict the increase in global warming count on too much water vapor in the atmosphere.
“[S]o he puts that much vapor in his model and of course he gets this,” Gray said. “He must get upper troposphere where the temperature is seven degrees warmer for a doubl[ing of] CO2. Well, the reason he got that was – why this upper-level warming was there – was he put too much water vapor in the model.”
