OOPS!!! "Since 1998, more than 31,000 American scientists from diverse climate-related disciplines, including more than 9,000 with Ph.D.s, have signed a public petition announcing their belief that “…there is no convincing scientific evidence that human release of carbon dioxide, methane, or other greenhouse gases is causing or will, in the foreseeable future, cause catastrophic heating of the Earth’s atmosphere and disruption of the Earth’s climate.” Included are atmospheric physicists, botanists, geologists, oceanographers, and meteorologists."

That Scientific Global Warming Consensus…Not!

Larry Bell

On June 19, apparently timed to warm up spirits at the Rio+20 meetings at the U.N. Conference on Sustainability that began the following day, Senator John Kerry gave a sizzling 55-minute indictment on the Senate floor of those who challenge global warming crisis claims. He referred to a “calculated campaign of disinformation”, which he said “…has steadily beaten back theconsensus momentum [italics added] for action on climate change and replaced it with timidity proponents in the face of millions of dollars of phony, contrived ‘talking points’, illogical and wholly unscientific propositions, and a general scorn for the truth wrapped in false threats about job loss and tax increase.” In his speech, Kerry called for the public to be “pounding on the doors of Congress” to act, and cataloged global perils such as drought, floods, wildfires, threatened coastlines, disease risks and more, noting “the danger we face could not be more real.”

Consensus momentum regarding action on climate change? Phony, contrived talking points, unscientific propositions, and a scorn for truth wrapped in false threats? Yes, he’s entirely correct on both accounts… but in the exact opposite direction that he, supported by representations in the “mainstream media”, has indicated.

Last August, Washington Post op-ed writer Richard Cohen scorned then-presidential candidate Rick Perry for publicly stating that he stood with an increasing number of scientists who have challenged the existence of man-made global warming threats. According to Cohen, “There were some, of course, just as there are some scientists who are global warming skeptics, but these few- about 2% of climate researchers- could hold their annual meeting in a phone booth, if there are any left. (Perhaps 2% of scientists think they are).”

This would require a pretty big phone booth, and actually, there really are many of those “global warming skeptics” still remaining. In fact, that number (yes- scientists with solid credentials) has been rapidly multiplying, not diminishing.

As Joseph Bast who heads the Heartland Institute points out, “It is important to distinguish between the statement, which is true, that there is no scientific consensus that AGW [anthropogenic (human-caused) global warming] is or will be a catastrophe, and the also-true claims that the climate is changing (of course it is, it is always changing), and that most scientists believe there may be a human impact on climate (our emissions and alterations of the landscape are surely having an impact, though they are often local or regional (like heat islands) and small relative to natural variation).” And yes, I truly do hold both Joe Bast and Heartland in high esteem.

Since 1998, more than 31,000 American scientists from diverse climate-related disciplines, including more than 9,000 with Ph.D.s, have signed a public petition announcing their belief that “…there is no convincing scientific evidence that human release of carbon dioxide, methane, or other greenhouse gases is causing or will, in the foreseeable future, cause catastrophic heating of the Earth’s atmosphere and disruption of the Earth’s climate.” Included are atmospheric physicists, botanists, geologists, oceanographers, and meteorologists.

So where did that famous “consensus” claim that “98% of all scientists believe in global warming” come from? It originated from an endlessly reported 2009 American Geophysical Union (AGU) survey consisting of an intentionally brief two-minute, two question online survey sent to 10,257 earth scientists by two researchers at the University of Illinois. Of the about 3.000 who responded, 82% answered “yes” to the second question, which like the first, most people I know would also have agreed with.

Then of those, only a small subset, just 77 who had been successful in getting more than half of their papers recently accepted by peer-reviewed climate science journals, were considered in their survey statistic. That “98% all scientists” referred to a laughably puny number of 75 of those 77 who answered “yes”.

That anything-but-scientific survey asked two questions. The first: “When compared with pre-1800s levels, do you think that mean global temperatures have generally risen, fallen, or remained relatively constant?” Few would be expected to dispute this…the planet began thawing out of the “Little Ice Age” in the middle 19th century, predating the Industrial Revolution. (That was the coldest period since the last real Ice Age ended roughly 10,000 years ago.)

The second question asked: “Do you think human activity is a significant contributing factor in changing mean global temperatures?” So what constitutes “significant”? Does “changing” include both cooling and warming… and for both “better” and “worse”? And which contributions…does this include land use changes, such as agriculture and deforestation?
