The University of Illinois conducted a survey of more than 3000 scientists (the scientists approached were listed in the 2007 edition of the American Geological Institute’s Directory of Geoscience Departments - so these are real scientists working in this field)
The questions asked (1) Have mean global temperatures risen compared to pre-1800s levels, and (2) 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.
From several sources:
Significant omission: over 10,000 were polled, and less than a third responded. They didn’t ask if there is a continued threat. In fact, they didn’t ask much did they?
A survey, “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”. If they don’t believe it in today’s climate (pardon the pun)of political correctness they won’t be getting any research funds and likely would be out of a job. So a big whooooptodo…on that finding. I’m only surprised it’s not 99.9%.
This is a particularly ridiculous example of how to get the answer you want from a poll, by carefully choosing the wording of the questions. And it’s so transparent it’s laughable. No-one with a brain will be fooled.
I’m a skeptic but I would certainly answer yes to the first question - of course temperatures have risen. I might even say yes to the second question - the real question is, how significant is man’s role, and is it due to CO2 or other factors.
Code:
If I didn't know a thing about AGW I would believe the skeptics based on these comments. The pro's have very little knowledge and prefer to attack the skeptic rather than have any meaningful conversation. However, I have been studying the CO2 cycle years before the invention AGW. AGW is garbage. Man’s contribution to greenhouse CO2 warming is .117% that's one tenth of one percent or in other words, the ability to raise the earth temp by .0001% . If we cut our CO2 by 1/2, that would result in a .00005% change in temp.

"Writing in the publication Eos, Transactions, American Geophysical Union, Doran and Zimmerman conclude, “the debate on the authenticity of global warming and the role played by human activity is largely nonexistent among those who understand the nuances and scientific basis of long-term climate processes.” "
Or
We know best how to keep our jobs
“the debate on the authenticity of global warming and the role played by human activity is largely nonexistent among those who understand the nuances and scientific basis of long-term climate processes.” This quote demands a correction. NO ONE, I repeat NO ONE understands the scientific basis of long term climate processes. Freeman Dyson put it best when he said that climate is the most complicated subject he could think of and climatologists were hiding behind their computer models sending out predictions of doom and gloom.
Code:
There are several layers of self-selection going on with this survey which, taken all together, make the results questionable to say the least.
If you look at the education of a meteorologist and a climatologist you will find that the two disciplines bifurcate rather late in the process. Those who find the arguments for human generated climate change compelling will tend to want to specialize in it and when they hang out their shingle it will say "climatologist". Those who find the arguments less credible are likely to chose a different specialization.
I bet 75% of home buyers though home prices would never come down this far too. So much for consensus.
Code:
I would like to know the number I scientists that want there to be a correlation between human activity and global warming. Oh remember, it was about global warming, not just climate change.
So, the survey was just another dubious survey with a meaningless result.
