You'll see this word in almost every newspaper article on global warming..."consensus". But is there really one in the scientific community? In 2003 Professor Dennis Bray of the GKSS Institute of Coastal Research in Geesthacht, Germany did a poll of the some of the worlds leading climatologists. And published the results to his poll in this paper.... http://www.sepp.org/Archive/NewSEPP/Bray.htm
In summary almost as many climatologists disagree at some level that our current global warming cycle is caused by man as agree with it.
50/50 is not a consensus.
