From the desmogblog:
In an interview with ABC News, Dr. Fred Singer the “grandfather of the global warming “skeptics”", had a typical answer to a relevant question:
ABC Anchor, Dan Harris: There are so many scientists who disagree with what you’re saying, the IPCC [Intergovernmental Panel on Climate Change], NASA, NOAA, the National Academy of Science, the American Association for the Advancement of Science, the American Geophysical Union, the American Meteorological Society - we’re talking about scientists all over the globe.
S. Fred Singer: What can I say? They’re wrong.
Harris: All of those people are wrong?
S. Fred Singer: Yes.
It takes some pretty big stones (and ego) to stand up and say that “they’re wrong, I’m right” without anything to back up the assertion. It doesn’t take a “consensus” to realize that Galileo’s impact on science will continue to be measured just a little bit more substantially than Dr. Singer.


Rational is not necessary - the sign of a true fanatic.
