Yes on warming, no on humans causing it

Global warming is happening, but humans are not the cause, one of the nation�s top experts on hurricanes said Monday morning.
Bill Gray, who has studied tropical meteorology for more than 40 years, spoke at the Larimer County Republican Club Breakfast about global warming and whether humans are to blame. About 50 people were at the talk.

Gray, who is a professor at Colorado State University, said human-induced global warming is a fear perpetuated by the media and scientists who are trying to get federal grants.

�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. �I�m sure that�s it.�

At the breakfast, Gray said 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,� he said.

But even if humans cause global warming, there�s not much people can do, Gray said. China and India will continue to pump out greenhouse gases, and alternative energy sources are expensive.

�Why do it if it�s not going to make a difference anyway?� he said. �Whether I�m right or wrong, we can�t do anything about it anyway.�
