I do know where that number (95% of climate scientists believe that human activity is a major contributor to global warming) is coming from, and it is not the news media, or some blog....That is where you get your denialist crap... http://tigger.uic.edu/~pdoran/012009_Doran_final.pdf
Setting aside the numerous technical issues like limiting IP's to one vote, actually not knowing who the person voting was and simple methodology issues like 90% of scientists polled being from the US lets' look at the question.

2. Do you think human activity is a significant contributing factor in changing mean global temperatures?
What is the quantification of significant? For example a homeless person would consider $100 a significant amount of money while Donald Trump would consider it peanuts. The question itself is subjective and without quantifying the meaning of the term "significant" the results should not be surprising. This is a carefully worded simplistic question to get a desired result.
Having said that the 95% (actually 97.4) figure comes from a grand total of 79 self described climate scientists. There waa 10K this survey was sent too with approximately 3000 responding. That 3000 was whittled down to 79 to arrive at that number.
Shall I go on?

Carry on if you like, but even you have to admit that the earth is warming, right? I agree with the science, and you can do as you want...What will be will be, but the cause is becoming more obvious every year...Even past warming events involved CO2...

Sanspeur I don't think there is too much evidence to suggest otherwise, the debate remains over what is causing it, to what degree and if there is really anything we can do about. Climate is very complex and the science is in it's infancy. There is also the political issues such as if we stop burning coal to what purpose does that serve if a country like China is increasing their consumption by enormous quantities. If you want a perspective on that they burn 5X what we do and their consumption rate within the last decade alone has increased what we burn in total.

So, what do you suggest, that we just throw up our hands and carry on polluting because other countries do it?

76 out of 79 hand picked climate scientists... 76??????
And you think 76 scientists is critical mass? I'm sure somebody could find 76 somewhere else that disagree with your 76.

Yes, the earth is warming.... and cooling. It always has and always will. Yes, I believe the science.
And you have it backwards. Warming causes increases in CO2.
So, what do you suggest, that we just throw up our hands and carry on polluting because other countries do it?
CO2 is not pollution.
Yes, I agree that we should address pollution. And we have done so quite well for a few decades. Those efforts to control real pollution should continue.
Unfortunately, the CO2 alarmists have taken our focus, money and resources from fighting real pollution.

The 79 were picked based on their answers to the questionnaire but you could certainly set a bias criteria. One specific question asked them something along the lines of what was their predominant field and that itself has issues. If you're a geologist studying ancient climate are you a geologist or climate scientist?

Actually, the percentage of geologists who answered "Yes" to question #2 (whether climate change was the result of humans) was only 47% (48 of 103), the lowest percentage of the survey.
