Seasonal hurricane forecasts

Gray developed a seasonal hurricane forecasting methodology in the 1980s and began reporting his forecasts to the public. His forecasts are widely discussed in the U.S. media. Preliminary forecasts are released before the start of the hurricane season, and the forecasts are then revised as the season progresses. The forecasts establish an expectation of the hurricane activity for the year, but are frequently inaccurate, often requiring subsequent forecasts. In 2005

, for example, both the CSU team and NOAA significantly underestimated the actual hurricane totals despite issuing updated estimates as late as August of that year.

Stance on global warming



Gray is skeptical of current theories of human-induced global warming, which he says is supported by scientists afraid of losing grant funding
and promoted by government leaders and environmentalists seeking world government

.
He believes that humans are not responsible for the warming of the earth and has stated that "We're brainwashing our children."
He asked, "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?"

Gray said those who had linked global warming to the increased number of hurricanes in recent years were in error. He cites statistics showing that there were 101 hurricanes from 1900 to 1949, in a period of cooler global temperature, compared to 83 from 1957 to 2006 when the earth warmed.

Gray does not say there has not been any warming, but states "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."

According to an earlier interview reported by Joel Achenbach, Gray had similarly said that the current warming in the past decades is a natural cycle, driven by a global ocean circulation

 proposals. In every case he has turned down the global warming research component because he believed it was not up to standards, but recommended that Gray's hurricane research be funded.

Webster, who has co-authored other scientific papers with Gray, is also critical of Gray for his personal attacks on the scientists with whom he disagrees. "Bill, for some very good reasons, has been the go-to man on hurricanes for the last 35 years," says Webster. "All of a sudden there are a lot of people saying things Bill doesn't agree with. And they're getting a lot of press—more press than I like, actually. I like the ivory tower
