The 97% statistic that all Climate Scientist agree Man is primarily responsible for Anthropogenic Global Warming first appeared in 2009i in a study by University of Illinois master student Kendall Zimmerman and her advisor Peter Doran. It was a two question survey and only 5% of the people who answered ,a little over 150 , were actual Climate Scientists. The 97% comes from an even smaller sub-set of 79 people who were self-professed Climate Scientists with 50% of their research being conducted on the subject of Climate Change. So that 97% figure originally came from 79 Scientist who agreed that the Earth’s temperature has risen since the 1800’s and that Humans are likely a contributing factor. People used this Number and ran with it. When the evidence was running a little thin and people started questioning it in 2013 Australian blogger John Cook and his buddies reviewed some abstracts of peer reviewed papers published between 1991 to 2011. What were his findings ? :Coincidently that exactly 97% of Scientist either explicitly or implicitly made the assertion that Humans were somewhat responsible for warming not even Climate Change ,BUT WARMING, his work was debunked as CRAP in Science and Education I August 2013. For example, David R Legates ( a professor at the University of Delaware and frmer director of it’s Center for Climatic Research) and three coauthors reviewed the same papers as did Mr. Cook and found “ only 41 papers—0.3 percent of all 11,944 abstracts or 1.o percent of the 4,014 expressing an opinion , and not 97.1 percent--- had been found to endorse” the claim that human Activity is causing most of the current warming. Elsewhere , climate scientists including Craig Idso, Nicola Scafetta, Nir J. Shaviv and Nils-Axel Morner. Whose research questions the alleged consensus, protested that Mr. Cook ignored or misrepresented their work. Show less
It's not 97% of ALL climate scientist. It's 97% of climate scientist that participated in the faux survey.
Stop reading crackpot sites. The world will make much more sense. AMERICAN SCIENTIFIC SOCIETIES Statement on Climate Change from 18 Scientific Associations "Observations throughout the world make it clear that climate change is occurring, and rigorous scientific research demonstrates that the greenhouse gases emitted by human activities are the primary driver." (2009)2 American Association for the Advancement of Science "The scientific evidence is clear: global climate change caused by human activities is occurring now, and it is a growing threat to society." (2006)3 American Chemical Society "Comprehensive scientific assessments of our current and potential future climates clearly indicate that climate change is real, largely attributable to emissions from human activities, and potentially a very serious problem." (2004)4 American Geophysical Union "Human‐induced climate change requires urgent action. Humanity is the major influence on the global climate change observed over the past 50 years. Rapid societal responses can significantly lessen negative outcomes." (Adopted 2003, revised and reaffirmed 2007, 2012, 2013)5 American Medical Association "Our AMA ... supports the findings of the Intergovernmental Panel on Climate Change’s fourth assessment report and concurs with the scientific consensus that the Earth is undergoing adverse global climate change and that anthropogenic contributions are significant." (2013)6 American Meteorological Society "It is clear from extensive scientific evidence that the dominant cause of the rapid change in climate of the past half century is human-induced increases in the amount of atmospheric greenhouse gases, including carbon dioxide (CO2), chlorofluorocarbons, methane, and nitrous oxide." (2012)7 American Physical Society "The evidence is incontrovertible: Global warming is occurring. If no mitigating actions are taken, significant disruptions in the Earth’s physical and ecological systems, social systems, security and human health are likely to occur. We must reduce emissions of greenhouse gases beginning now." (2007)8 The Geological Society of America "The Geological Society of America (GSA) concurs with assessments by the National Academies of Science (2005), the National Research Council (2006), and the Intergovernmental Panel on Climate Change (IPCC, 2007) that global climate has warmed and that human activities (mainly greenhouse‐gas emissions) account for most of the warming since the middle 1900s." (2006; revised 2010)9 SCIENCE ACADEMIES International Academies: Joint Statement "Climate change is real. There will always be uncertainty in understanding a system as complex as the world’s climate. However there is now strong evidence that significant global warming is occurring. The evidence comes from direct measurements of rising surface air temperatures and subsurface ocean temperatures and from phenomena such as increases in average global sea levels, retreating glaciers, and changes to many physical and biological systems. It is likely that most of the warming in recent decades can be attributed to human activities (IPCC 2001)." (2005, 11 international science academies)10 U.S. National Academy of Sciences "The scientific understanding of climate change is now sufficiently clear to justify taking steps to reduce the amount of greenhouse gases in the atmosphere." (2005)11 U.S. GOVERNMENT AGENCIES U.S. Global Change Research Program "The global warming of the past 50 years is due primarily to human-induced increases in heat-trapping gases. Human 'fingerprints' also have been identified in many other aspects of the climate system, including changes in ocean heat content, precipitation, atmospheric moisture, and Arctic sea ice." (2009, 13 U.S. government departments and agencies)12 INTERGOVERNMENTAL BODIES Intergovernmental Panel on Climate Change “Warming of the climate system is unequivocal, and since the 1950s, many of the observed changes are unprecedented over decades to millennia. The atmosphere and ocean have warmed, the amounts of snow and ice have diminished, and sea level has risen.”13 “Human influence on the climate system is clear, and recent anthropogenic emissions of greenhouse gases are the highest in history. Recent climate changes have had widespread impacts on human and natural systems.”14 https://climate.nasa.gov/scientific-consensus/
These are all extreme left-wing organizations who want a global government controlling the masses via taxes and regulations. Stop falling for this globalism crap.

Yeah, you see, the planet's climate was supposed to remain in the era of the Little Ice-Age for all of eternity, and never get any warmer. That's it. Any increase in global temperatures beyond those averages recorded during the late 18th century or early 19th century, are abnormal.
What nonsense! Science has nothing to do with opinions. It has to do with facts! It makes absolutely no difference what scientists believe. In Science, the only thing that matters is what they can prove. through peer-reviewed scientific studies that use the Scientific Method. And among those, 100% of Studies in the last 20 years (at least) agree that 1- Global Warming is happening 2- That it's cause by Human Activity and 3- That the consequences will be negative for the human Society.
Funny how agencies funded by the government, all agree with the global warmists that we need to turn our lives and wealth over to government, and allow them to have complete control over all of our industries, our economies, and tell us how to live our lives. Oh, and we only have ten years in which to act to prevent global warming, or it will be too late. Of course they have been telling us every ten years, since the 1970s, that we only have ten years in which to act, or it will be too late. Every ten years, they tell us we only have ten years, then they reset the clocks for ten years, rinse, repeat.
Quote the negative or explicitly doubtful position on human caused global warming on a single peer-reviews paper in the last 20 years. The matter was put to rest some 20 years ago (at least). There is not even a debate in Science. There is a Scientific Consensus 1- Global Warming exists 2- It is caused by Human Activity 3- Consequences for Human communities will be dire if left unchecked. There is no 97% ... nothing. There is 100% of studies in (at least) the last 20 years. So if you are still a Science denier... you are living over 20 years in the past. Denying this is like denying that the Earth is round. The Theory of Evolution. The Theory of Gravity . Relativity. Quantum Physics.... It's just settled science.

I don't know. But I'm sure the Global Warming denialists are the same idiots who claim that children shouldn't vaccinate against the measles, which has given us an outbreak that has not been seen in 50 years Science deniers show the same kind of ignorance.
Let's just cut to the chase. 100% of Climatologists know "Climate's gonna climate". It doesn't make two shits whether man is here or not. Scientists have proven the earth has been through both global warming AND and an ice age with no presence of man in sight. Yet the hand wringing Chicken Little types think somehow ending hamburgers, big sodas, motor cars, reasonably comfortable homes cooled and heated by electricity are somehow going to escalate Mother Nature into some sort of frenzy. WE MUST HAVE SOME SORT OF TAX to end these innovations to make us all 3rd World Nations. The UN has concluded as such in Agenda 21, and damn it all............we missed the Faux Paris Accord!
I'm pretty sure that AGW is a complete crock, but I would also agree that human's have an effect upon global warming. It's called the observer effect which states that observation affects the outcome. The most notable of this is the double slit experiment.
Its not surprising that they were only able to find 79 climate scientists. Only a very small number of people are climate scientists. Its interesting that out of the 79 climate scientists asked only 2 didn't believe humans were primary responsible for the warming. I would have expected more like 20-40 if there was a lot of skepticism. As for the Legates paper, those 41 papers are those that very clearly stated the standard claim on climate change, that human activity is very likely causing most of the current warming. 23% of the 4,014 papers made an unqualified support in climate change supporting that humans are causing climate change without more detail into the probability. Further, 72.5% give an implicit support of human-caused climate change, by assuming that humans are the main cause. It sounds like he will needs a very specific endorsement with the right wording and that requirement is a little ridiculous, because all we really need is a general endorement of some kind. Another problem is that you are ignoring other studies into the percent of scientists who agree humans are causing climate change all that show that the vast majority of climate scientists agree humans are causing climate change: Verheggen et al., 2014 Powell, 2013 Lefsrud and Meyer, 2012 Farnsworth and Lichter, 2011 Anderegg, Prall, Harold, and Schneider, 2010 Bray and von Storch, 2008 STATS, 2007 Oreskes, 2004 Bray and von Storch, 2003
An ignorant statement at best. Global warming may or may not be happening based on how it is measured. There are probably at least a thousand ways to measure it with a thousand different answers. Whether it will be negative for human society depends on which human society you pick and how you rate the consequences. It is a fact that some people believe humans would be better off, if their were fewer of us.
It is actually warmer than the little ice age. The argument is that humans are causing very rapid climate change, not that all change is bad.
Could it be that some people will dismiss any scientific study they find inconvenient as "left wing"?
Haha! The AAAS only publishes the most prestigious scientific journal in the world, Science. The ACS is the world's largest chemistry society. I am member of the ACS. I tell you, they are no left wing organization. They just advocate for advancement of Chemistry is research and education, mostly to the benefit of their members and society as a whole. Educate yourself before you spout such nonsense.
