Prof Gray, Hurricane Expert - "Humans Not Cause of Warming"

Continuing the lively debate on global warming. One of the point made in this article confirms an earlier post that compares our ability to predict weather a few days out to the really, really long term forecasts. This expert agrees with your fearless blogger.

"Global warming is happening, but humans are not the cause," according to Bill Gray, one of the nation’s top experts on hurricanes. Gray, who has studied tropical meteorology for more than 40 years, is a professor at Colorado State University. He further stated that "human-induced global warming is a fear perpetuated by the media and scientists who are trying to get federal grants. The Earth was warmer in some medieval periods than it is today. Current weather models are good at predicting weather as far as 10 days in advance, but predicting up to 100 years into the future is a great act of faith, and I don’t believe any of it.”

“I think we’re coming out of the little ice age, and warming is due to changes to ocean circulation patterns due to salinity variations,” Gray said.



Gray’s view has been challenged, however.

Roger Pielke Jr., director of the Center for Science and Technology Policy Research at the University of Colorado, said, “Bill Gray is a widely respected senior scientist who has a view that is out of step with a lot of his colleagues’, but challenging widely held views is “good for science because it forces people to make their case and advances understanding. We should always listen to the minority."

I have shamelessly rearranged this article a bit without disturbing its meaning. To read the whole thing go here.
