Is Global Warming Man-Made????

Excerpts from a lecture by Fred Singer....

The second reason not to rely on a “scientific consensus” in these matters is that this is not how science works. After all, scientific advances customarily come from a minority of scientists who challenge the majority view—or even just a single person (think of Galileo or Einstein). Science proceeds by the scientific method and draws conclusions based on evidence, not on a show of hands.

But aren’t glaciers melting? Isn’t sea ice shrinking? Yes, but that’s not proof for human-caused warming. Any kind of warming, whether natural or human-caused, will melt ice. To assert that melting glaciers prove human causation is just bad logic.

What about the fact that carbon dioxide levels are increasing at the same time temperatures are rising? That’s an interesting correlation; but as every scientist knows, correlation is not causation. During much of the last century the climate was cooling while CO2 levels were rising. And we should note that the climate has not warmed in the past eight years, even though greenhouse gas levels have increased rapidly.

What about the fact—as cited by, among others, those who produced the IPCC report—that every major greenhouse computer model (there are two dozen or so) shows a large temperature increase due to human burning of fossil fuels? Fortunately, there is a scientific way of testing these models to see whether current warming is due to a man-made greenhouse effect. It involves comparing the actual or observed pattern of warming with the warming pattern predicted by or calculated from the models. Essentially, we try to see if the “fingerprints” match—“fingerprints” meaning the rates of warming at different latitudes and altitudes.

For instance, theoretically, greenhouse warming in the tropics should register at increasingly high rates as one moves from the surface of the earth up into the atmosphere, peaking at about six miles above the earth’s surface. At that point, the level should be greater than at the surface by about a factor of three and quite pronounced, according to all the computer models. In reality, however, there is no increase at all. In fact, the data from balloon-borne radiosondes show the very opposite: a slight decrease in warming over the equator.

The fact that the observed and predicted patterns of warming don’t match indicates that the man-made greenhouse contribution to current temperature change is insignificant. This fact emerges from data and graphs collected in the Climate Change Science Program Report 1.1, published by the federal government in April 2006 (see www.climatescience.gov/Library/sap/sap1-1/finalreport/default.htm ). It is remarkable and puzzling that few have noticed this disparity between observed and predicted patterns of warming and drawn the obvious scientific conclusion.

Fred Singer? Are you serious? He used to lobby for the tobacco industry, where he claimed that tobacco smoke didn't cause cancer.

And how, pray tell, does that affect the validity of his points? If his information is wrong, please say so and prove it. If his reasoning is flawed and faulty, then please demonstrate it.
