(1929) A pioneer in the science of hurricane forecasting, Gray is the Emeritus Professor of Atmospheric Science at Colorado State University (CSU) and head of the Tropical Meteorology Project at CSU's Department of Atmospheric Sciences. He pioneered the concept of "seasonal" hurricane forecasting — i.e., predicting months in advance the severity of the coming hurricane season.
A staunch and outspoken AGW skeptic
"How can we trust climate forecasts 50 and 100 years into the future (that can't be verified in our lifetime) when they are not able to make shorter seasonal or yearly forecasts that could be verified?"
He believes that there probably has been some human-caused warming: "I don't question that. And humans might have caused a very slight amount of this warming. Very slight. But this warming trend is not going to keep on going. My belief is that three, four years from now, the globe will start to cool again, as it did from the middle '40s to the middle '70s."
Gray states his case for skepticism
The following video allows Gray to succinctly and clearly state his case (he starts at about 2 minutes).
