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.”
