For those thinking GW isnt happening reality is the northwest passage is free of enough ice for most of the year for the northwest passage to be considered a viable shipping route. Arctic Meltdown Opens Fabled Northwest Passage | LiveScience
Well considering it was first navigated in 1903, was it navigable at certain times 200 years ago? 500 years ago? 1000 years ago?

dude we need to get you a time machine so you can get yourself back to the present.
LOL.
First of all, there has never been a time in living memory when "the northwest passage is free of enough ice for most of the year" (quote from you).
There has been a few days per year when the NWP has been opened over the last few years. the summer of 2013 actually saw quite a bounce back from the 2012 low.

You would like to discuss the Cook study instead of the Doran study then? Which one would like to discuss, pick one and we'll debate the findings as long as you can refrain from hurling insults. Are you capable of that?
As I've already pointed out the Doran study is the only one that has directly polled scientists and is so often cited.
The Doran survey is wholly unreliable, considering the 77 who responded out of the 10,257 who were asked to participate (0.75%) did so anonymously. We really do not know who actually responded. It could be some earth scientist's niece or nephew for all we know. Or it may have been just one earth scientist responding positively 75 times.
To put any stock into either study would be stupid, since neither are credible or provide an accurate assessment of the scientific community's consensus on the subject.

Alarmists know this; but, it does not stop them from perpetuating the distortion of truth - ends always justify their means.

The Facts
Stewart is referring to a survey done for the American Geophysical Union in 2009 by researchers for the University of Illinois in Chicago. Peter Doran, associate professor of earth and environmental sciences, along with former graduate student Maggie Kendall Zimmerman, in 2008 sent a simple survey with nine questions to more than 10,000 experts listed in the 2007 edition of the American Geological Institute’s directory of geoscience departments.
They ended up getting responses from 3,146 scientists, and then publicized the results from two questions: (1) Have mean global temperatures risen compared to pre-1800s levels? (2) Has human activity been a significant factor in changing mean global temperatures?
The results? About 90 percent of the scientists agreed with the first question and 82 percent with the second.
How about we try to be current with these studies and stop cherry picking?
John Cook et al, 2013
Cook et al examined 11,944 abstracts from the peer-reviewed scientific literature from 1991–2011 that matched the topics 'global climate change' or 'global warming'. They found that, while 66.4% of them expressed no position on anthropogenic global warming (AGW), of those that did, 97.1% endorsed the consensus position that humans are causing global warming.
Farnsworth and Lichter, 2011
In an October 2011 paper published in the International Journal of Public Opinion Research, researchers from George Mason University analyzed the results of a survey of 489 scientists working in academia, government, and industry. The scientists polled were members of the American Geophysical Union or the American Meteorological Society and listed in the 23rd edition of American Men and Women of Science, a biographical reference work on leading American scientists. Of those surveyed, 97% agreed that global temperatures have risen over the past century. Moreover, 84% agreed that "human-induced greenhouse warming" is now occurring. Only 5% disagreed with the idea that human activity is a significant cause of global warming. Surveys of scientists' views on climate change - Wikipedia, the free encyclopedia

Isn't 97% of 34% smaller than 97%?
