Ofta upprepas att 97% av alla klimatforskare i världen är överens om att den globala klimatförändringen och växthuseffekten är skapad av människans utsläppt av koldioxid. Detta är helt osant enligt författaren Mark Steyn som skrev boken: ”A Disgrace to the Profession”.

Dessa siffror kommer från en enkätundersökning utförd av Margaret R. K. Zimmerman vid ”University of Illinois” från 2008.
Vad som egentligen hände var att Zimmerman skickade ut mail om en online-enkät med två frågor till 10, 257 ”earth scientists” inkluderat klimatologer av dess svarade de endast 3, 146 stycken. Av dessa kom 96, 2% från Nordamerika varav 6.2% kom från Kanada. De flesta i USA kom från Kalifornien.
Zimmerman fortsatte sedan med att utesluta och skära ned antalet klimatexperter till endast 79 st och av dessa var 97% eniga om att människans koldioxid ligger bakom klimatförändringarna.
Bland journalister ute i världen har dessa data tolkats till att 97% av världens klimatforskare eller att 10,257 ”klimatexperter” är eniga om att människan är orsaken till den globala klimatförändringen.
Från boken: ”A Disgrace to the Profession”:
”An opinion survey of earth scientists on global climate change was conducted by Margaret R K Zimmerman, MS, and published by the University of Illinois in 2008.
Aside from his support from Dr Pantsdoumi, Mann often claims the imprimatur of “settled science”: 97 per cent of the world’s scientists supposedly believe in catastrophic anthropogenic global warming requiring massive government intervention. That percentage derives from a survey conducted for a thesis by M R K Zimmerman.
The “survey” was a two-question, online questionnaire sent to 10,257 earth scientists, of whom 3,146 responded.
Of the responding scientists, 96.2 per cent came from North America.
Only 6.2 per cent came from Canada. So the United States is overrepresented even within that North American sample.
Nine per cent of US respondents are from California. So California is overrepresented within not just the US sample: it has over twice as large a share of the sample as Europe, Asia, Australia, the Pacific, Latin America and Africa combined.
Of the ten per cent of non-US respondents, Canada has 62 per cent.
Not content with such a distorted sample, the researchers then selected 79 of their sample and declared them “experts.”
Of those 79 scientists, two were excluded from a second supplementary question. So 75 out of 77 made it through to the final round, and 97.4 per cent were found to agree with “the consensus”. That’s where the 97 per cent comes from.
So this is a very Michael Mann “reconstruction”: just as a couple of Californian bristlecones can determine the climate for a millennium, so a couple of dozen Californian scientists can determine the consensus of the world.
Nonetheless, the compilers also invited comments from respondents and published them in the appendices. In terms of specific scientific material, the hockey stick attracted three comments – one blandly positive, the other two not so much.”
Mike Adams på Natural News kommenterar:
”So if I send out an email survey to 1000 people, and then I hand-pick the 75 responses I like the best, then can I proclaim those results to be ”settled science” too? Will Al Gore champion my cause and demand billions in reparations from first world nations on my behalf?
Of course not. The very idea is total fraud. Yet this is the science fraud upon which the entire mainstream media and government climate frenzy is based.”
