How arrogant art thy name-callers?

Ivar Giaevar

The guys at Popular Tech have done a Very Nice List. They’ve put together seven names of eminent scientists who are skeptical of man-made climate catastrophe, along with their stellar biographies and quotes. It tells us nothing about the climate, but before you write it off as just a fallacious appeal to authority, ponder that these eminent people are the same people that teenage tree-huggers would call “deniers”.

To see just how mindlessly puerile “denier” is, try the thought experiment of putting those-who-use-it in the same room as one of the more notable “deniers”.

Julia Gillard (the new PM downunder) used “denier” 11 times in one recent speech. So imagine she’s in a room talking with, say, Ivar Giaever. She studied arts and law, he got a PhD in theoretical physics two years before she was born, and won a Nobel Prize by the time she was nine. Picture him talking atmospheric physics and her telling him he’s a denier.

A Nobel doesn’t mean he’s right, but when Gillard says “Denier” she is referring to thousands of people including Freeman Dyson, Ivar Giaever (Nobel Prize), Robert Laughlin [...]

Consensus? What consensus?

How many scientists does it take to prove the debate is not over? More than 30,000 scientists have signed The Petition Project. More than 9,000 of them have PhDs (not that that proves anything about carbon, but it does prove something about the myth of “consensus”). The petition’s wording is unequivocal:

“There is no convincing scientific evidence that human release of carbon dioxide, methane, or other greenhouse gasses is causing or will, in the foreseeable future, cause catastrophic heating of the Earth’s atmosphere and disruption of the Earth’s climate. Moreover, there is substantial scientific evidence that increases in atmospheric carbon dioxide produce many beneficial effects upon the natural plant and animal environments of the Earth.” Source:

The Petition Project is funded by donations from individuals and run by volunteers. It receives no money from industry or companies. In late 2007, The Petition Project re-did the petition to verify names again.

AGW says: Everyone knows the petition is bogus and filled with duplicate and fake names.

Skeptics say: Name 10 fakes.
