Global warming catastrophists like to claim that 98% of the worlds scientists “agree” that climate change is going to kill us all unless we do “something”. Turns out that consensus figure is a complete joke.
So where did that famous âconsensusâ claim that â98% of all scientists believe in global warmingâ 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 âyesâ 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 â98% all scientistsâ referred to a laughably puny number of 75 of those 77 who answered âyesâ.
That anything-but-scientific survey asked two questions. The first: âWhen compared with pre-1800s levels, do you think that mean global temperatures have generally risen, fallen, or remained relatively constant?âÂ Few would be expected to dispute thisâŠthe planet began thawing out of the âLittle Ice Ageâ in the middle 19thÂ 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: âDo you think human activity is a significant contributing factor in changing mean global temperatures?â So what constitutes âsignificantâ? Does âchangingâ include both cooling and warmingâŠ and for both âbetterâ and âworseâ? And which contributionsâŠdoes this include land use changes, such as agriculture and deforestation?
No one has ever been able to measure human contributions to climate. Donât even think about buying a used car from anyone who claims they can.As Senator James Inhofe, Ranking Member of the Senate Committee on Environment and Public Works has observed: âThe notion of a âconsensusâ is carefully manufactured for political and ideological purposes. Its proponents never explain what âconsensusâ they are referring to. Is it a âconsensusâ that future computer models will turn out correct? Is it a âconsensusâ that the Earth has warmed? Proving that parts of the Earth have warmed does not prove that humans are responsible.â
