As relates to consensus? Yes, you made them up. Your fake lols don't change that.Thats adorable how you make up numbers for attention. Oh toddster, my attention comes free, you don't have to embarrass yourself for it.When the overwhelonng majority of scientists call something extremely likely, that is significant.
75/77. Practically a guarantee.
DERP!
Thats adorable how you make up numbers for attention.
You think I made up those numbers? LOL!
Wow, and you sounded so knowledgeable in your refusal to give details.
Grown man typing fake lols = very frustrated.
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?â Few would be expected to dispute thisâŚthe planet began thawing out of the âLittle Ice Ageâ 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: 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 warming⌠and for both âbetterâ and âworseâ? And which contributionsâŚdoes 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
That Scientific Global Warming Consensus...Not!
A group of 3,146 earth scientists surveyed around the world overwhelmingly agree that in the past 200-plus years, mean global temperatures have been rising, and that human activity is a significant contributing factor in changing mean global temperatures.
Peter Doran, University of Illinois at Chicago associate professor of earth and environmental sciences, along with former graduate student Maggie Kendall Zimmerman, conducted the survey late last year.
The findings appear January 19 in the publication Eos, Transactions, American Geophysical Union.
In trying to overcome criticism of earlier attempts to gauge the view of earth scientists on global warming and the human impact factor, Doran and Kendall Zimmerman sought the opinion of the most complete list of earth scientists they could find, contacting more than 10,200 experts around the world listed in the 2007 edition of the American Geological Institute's Directory of Geoscience Departments.
Experts in academia and government research centers were e-mailed invitations to participate in the on-line poll conducted by the website questionpro.com. Only those invited could participate and computer IP addresses of participants were recorded and used to prevent repeat voting. Questions used were reviewed by a polling expert who checked for bias in phrasing, such as suggesting an answer by the way a question was worded. The nine-question survey was short, taking just a few minutes to complete.
Two questions were key: have mean global temperatures risen compared to pre-1800s levels, and has human activity been a significant factor in changing mean global temperatures.
About 90 percent of the scientists agreed with the first question and 82 percent the second.
In analyzing responses by sub-groups, Doran found that climatologists who are active in research showed the strongest consensus on the causes of global warming, with 97 percent agreeing humans play a role. Petroleum geologists and meteorologists were among the biggest doubters, with only 47 and 64 percent respectively believing in human involvement. Doran compared their responses to a recent poll showing only 58 percent of the public thinks human activity contributes to global warming.
Scientists Agree Human-induced Global Warming Is Real, Survey Says
Doran found that climatologists who are active in research showed the strongest consensus on the causes of global warming, with 97 percent agreeing humans play a role.
Weird, no mention that they excluded all but 77 climatologists.
Funny that idiots think 75/77 means there is a consensus.
Played a role? Wow, so specific!
Gotta know the questions. Gotta ask a LOT of questions to "settle" the science.
âWhen compared with pre-1800s levels, do you think that mean global temperatures have generally risen, fallen, or remained relatively constant?â
They really dug deep with this one.
