"Because of climate’s high complexity, reliable prognoses just aren’t possible. Nature does what it wants, and not what the models present as prophesy. The entire CO2-debate is nonsense. Even if CO2 were doubled, the temperature would rise only 1°C. The remainder of the IPCC’s assumed warming is based purely on speculative amplification mechanisms. Even though CO2 has risen, there has been no warming in 13 years."
- Klaus-Eckart Puls, a German physicist and meteorologist according to Powerline Blog, stating that that one cannot predict future warming while predicting that future warming will only be at the low end of the predicted range of increased temperature based upon a doubling of CO2 and also repeating the 1998 myth.
Among those who doubt global warming, a Stanford University poll last year found that their skepticism had grown even stronger: Those who are extremely or very certain that global warming is not happening rose from 35 percent in 2010 to 53 percent in 2011. But those skeptics are a minority among Americans over all. The same poll found that 83 percent of adult Americans believe that the world's temperature has been going up. An even larger proportion of scientists actively working in climate change have similar views: 97 percent of them believe human-caused global warming is under way, although there is plenty of disagreement about the details.....
Academic pollsters, sociologists, historians, and anthropologists have been sorting through public attitudes about global warming for some time, but even though human behavior is central to the debate, the voices of social scientists are often lost in the din.
"In the end, all of the changes come down to what makes us behave the way we do and think the way we do," says Anthony Leiserowitz, director of the Yale Project on Climate Change Communication. "We need to understand us, not just the natural world."
