Here is a respected geologist's opinion, rather aggravated I must say, about the "myth" being put forth about man-caused global warming. Of course I agree with him and have other articles by Mr. Gerhard on this blog.
From Lee C. Gerhard [firstname.lastname@example.org], Senior Scientist Emeritus, Kansas Geological Survey, University of Kansas, Lawrence, Kansas
"Can anyone out there provide me with any empirical data in support of the theory that humans control climate warming? No, don't tell me that climate is changing - we geologists absolutely know that climate changes all the time, in both directions, and at many scales of time and intensity.
Don't give me results of computer modeling - those are not empirical data, they are the results of very serious attempts to place numbers on natural phenomena, but they are still based on assumptions and estimates, and have not been able to replicate past climate changes, particularly over the last 1500 years. Computer models are currently nothing more than scientific theories set to mathematical music.
Bring us some data, some values that support the concept. Right now the data show correlative changes in temperature and solar activity, modified by ocean current movement and orbital variations, many of which are predictable and which have operated to change climate for billions of years.Yes, there is an increase in carbon dioxide, but its effects drop logarithmically with its increase. Thus, it doesn't pose a threat. All told the full greenhouse effect, mostly water vapor, does make Earth a habitable planet.
Please don't argue that climate is changing at rates and intensities not ever seen before. That is just not true. Read the data already out there from the geologists and those who study past climate change.Tell me why otherwise competent scientists argue for their theory but fail to provide any support for their theory other than constant repetition of untrue statements and alarmist exaggerations.

Profile on Dr. Lee C. Gerhard:
Dr. Lee C. Gerhard is Principal Geologist of the Kansas Geological Survey, having retired from the Directorship and as State Geologist in 1999. He received his B.S. in geology at Syracuse University and the M. S. and Ph.D. degrees at the University of Kansas. He has combined academic, government, and industry leadership and technical appointments, including petroleum exploration, management of exploration programs, oil and gas regulation, reservoir geology, and management of research. His research interests are in carbonate sedimentology, petroleum geology, and environmental public policy. He has been the State Geologist of North Dakota, and led a marine ecology and geology research and teaching laboratory in the U. S. Virgin Islands. Prior to returning to Kansas, he was the Getty Professor of Geological Engineering at the Colorado School of Mines and operated an independent petroleum exploration company. He is licensed as geologist in Kansas and Wyoming.
Dr. Gerhard is an Honorary Member of the American Association of Petroleum Geologists, past president and Honorary Member of that society`s Division of Environmental Geosciences, an Honorary Member of the Association of American State Geologists, and an Honorary Member of the Kansas Geological Society.
He has published more than 150 papers and books on geology, petroleum exploration, natural resources, and environmental policy. He co-chaired the American Association of Petroleum Geologists Climate Change Issues Committee. He is active in wildlife and fisheries conservation issues in the U. S. and Canada, and has organized three recent major conferences on resource and environmental issues. He lectures widely in the U. S. and in Europe about environment and resources and global climate issues.
