Eerder schreef ik over het sprookje van de 97% klimaatconsensus.

Wijlen Michael Crichton was fel gekant tegen het gebruik van ‘consensus’ als ‘bewijs’ in de wetenschap en in het bijzonder wat betreft de AGW-hypothese (AGW = ‘Anthropogenic Global Warming’). In zijn voordracht voor het ‘California Institute of Technology’ in 2003 zei hij onder meer:

I want to pause here and talk about this notion of consensus, and the rise of what has been called “consensus science.” I regard consensus science as an extremely pernicious development that ought to be stopped cold in its tracks. Historically, the claim of consensus has been the first refuge of scoundrels; it is a way to avoid debate by claiming that the matter is already settled. Whenever you hear the consensus of scientists agrees on something or other, reach for your wallet, because you’re being had.

Let’s be clear: the work of science has nothing whatever to do with consensus. Consensus is the business of politics. Science, on the contrary, requires only one investigator who happens to be right, which means that he or she has results that are verifiable by reference to the real world.

In science consensus is irrelevant. What is relevant is reproducible results. The greatest scientists in history are great precisely because they broke with the consensus.

There is no such thing as consensus science. If it’s consensus, it isn’t science. If it’s science, it isn’t consensus. Period.

Ook Marcel Crok heeft er kritische aandacht aan geschonken.

Toch wordt er in het klimaatdebat nog steeds regelmatig gerefereerd aan die vermaledijde consensus.

James Taylor WGUL 1Onder de titel, ‘Peer-Reviewed Survey Finds Majority Of Scientists Skeptical Of Global Warming Crisis’, rapporteerde James Taylor onlangs over de laatste stand van zaken inzake de ‘consensus’ aan de hand van drie nieuwe enquêtes onder gekwalificeerde wetenschappers.

It is becoming clear that not only do many scientists dispute the asserted global warming crisis, but these skeptical scientists may indeed form a scientific consensus.

Don’t look now, but maybe a scientific consensus exists concerning global warming after all. Only 36 percent of geoscientists and engineers believe that humans are creating a global warming crisis, according to a survey reported in the peer-reviewed Organization Studies. By contrast, a strong majority of the 1,077 respondents believe that nature is the primary cause of recent global warming and/or that future global warming will not be a very serious problem.

The survey results show geoscientists (also known as earth scientists) and engineers hold similar views as meteorologists. Two recent surveys of meteorologists (summarized here and here) revealed similar skepticism of alarmist global warming claims.

According to the newly published survey of geoscientists and engineers, merely 36 percent of respondents fit the “Comply with Kyoto” model. The scientists in this group “express the strong belief that climate change is happening, that it is not a normal cycle of nature, and humans are the main or central cause.”

The authors of the survey report, however, note that the overwhelming majority of scientists fall within four other models, each of which is skeptical of alarmist global warming claims. ….

Taken together, these four skeptical groups numerically blow away the 36 percent of scientists who believe global warming is human caused and a serious concern. …

An […] interesting aspect of this new survey is that it reports on the beliefs of scientists themselves rather than bureaucrats who often publish alarmist statements without polling their member scientists. We now have meteorologists, geoscientists and engineers all reporting that they are skeptics of an asserted global warming crisis, yet the bureaucrats of these organizations frequently suck up to the media and suck up to government grant providers by trying to tell us the opposite of what their scientist members actually believe.

People who look behind the self-serving statements by global warming alarmists about an alleged “consensus” have always known that no such alarmist consensus exists among scientists. Now that we have access to hard surveys of scientists themselves, it is becoming clear that not only do many scientists dispute the asserted global warming crisis, but these skeptical scientists may indeed form a scientific consensus.
