Hurricane expert William Gray reported just a few days earlier, on April 27, that the number of major hurricanes making landfall on the U.S. Atlantic coast has declined in the past 40 years. Hurricane scientists reported in the April 18 Geophysical Research Letters that global warming enhances wind shear, which will prevent a significant increase in future hurricane activity. | | |However, hurricane expert Chris Landsea published a study on May 1 documenting that hurricane activity is no higher now than in decades past.

| − | Gray's statements on Global Warming have been the subject of criticism. Peter Webster, a Georgia Institute of Technology professor, has been part of the anonymous peer review on several of Gray's National Science Foundation 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.[7]

| − | 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. But he's become more and more radical."[7]

| − | Gray stated in March 2008, "“We should begin to see cooling coming on. 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.” [3]

| − | On April 11, 2008 The Rocky Mountain Collegian[4] ran an ad on page 6 of the offline paper version of the newspaper that accepted Gray's bet offer. The ad stated "I gladly accept your offer to bet over global warming. I suggest we each donate $5,000 to the Longbets.org charity to bet over whether temperatures will rise or fall in ten years. When the time’s up, Longbets will give all of our money to the winner’s designated charity, even if neither of us is around to see who’s won." The ad had been placed by a critic of Gray.[5]
