Question

This percentage is needed for a debate on global warming. Please include a source for the percentage!

Thanks a lot!

Answer 1

100% of the ones who know what they are talking about.

Answer 2

Percentage wise, well there cant be a number on that, so dont worry about using it for a debate...consider the number of "scientists" out there...the only ones counted are those who voice their opinions on the matter, meaning my guess is a very very small percentage of scientists actually would say it exists, but not because the evidence is not there...

That being said it is a real thing, funny how I remember researching this 13 years ago when it was not such a hot button issue, but the reasons for it are very hard to determine.  But only a completely biased ignoramous would think that they way we polute, burn up natural resources, and such , is a good thing for the Earth or us as humans...

Answer 3

The vast majority.  99+%?  Some sources:

Data about the scientific consensus in that site.  Here are some other quotes:

"Regardless of these spats, the fact that the community overwhelmingly supports the consensus is evidenced by picking up any copy of Journal of Climate or similar, any scientific program at the AGU or EGU meetings, or simply going to talk to scientists (not the famous ones, the ones at your local university or federal lab). I challenge you, if you think there is some un-reported division, show me the hundreds of abstracts at the Fall meeting (the biggest confernce in the US on this topic) that support your view - you won't be able to. You can argue whether the consensus is correct, or what it really implies, but you can't credibly argue it doesn't exist." -gavin

"There's a better scientific consensus on this [climate change] than on any issue I know - except maybe Newton's second law of dynamics". -Deltoid, ECOS Letter

Jerry Mahlman, NOAA

"The overwhelming majority of atmospheric scientists around the world and our own National Academy of Sciences are in essential agreement on the facts of global warming and the significant contribution of human activity to that trend."

Someone is sure to post about the "Oregon Petition".  It's a scam.
