The 30,000 Global Warming Petition Is Easily-Debunked Propaganda

To say that the oft-touted "30,000 Global Warming Petition" project stinks would be the understatement of the year.
I thought it would be timely to once again break down this flawed piece of global warming denier propaganda after it was mentioned last night in Daily Show host Jon Stewart's interview with US Energy Secretary of Energy, Dr. Stephen Chu.
.1% of Signers Have a Background in Climatology
The Petition Project website offers a breakdown of the areas of expertise of those who have signed the petition.
In the realm of climate science it breaks it breaks down as such:
Atmospheric Science (113)
Climatology (39)
Meteorology (341)
Astronomy (59)
Astrophysics (26)
So only .1% of the individuals on the list of 30,000 signatures have a scientific background in Climatology. To be fair, we can add in those who claim to have a background in Atmospheric Science, which brings the total percentage of signatories with a background in climate change science to a whopping .5%.
The page does not break out the names of those who do claim to be experts in Climatology and Atmospheric Science, which makes even that .5% questionable [see my section on "unverifiable mess" below].
This makes an already questionable list seem completely insignificant given the nature of scientific endeavor.
When I think I'm having chest pains I don't go to the dermatologist, I go to a cardiologist because it would be absurd to go to skin doctor for a heart problem. It would be equally absurd to look to a scientist with a background in medicine (of which there are 3,046 on the petition) for an expert opinion on the science of climate change. With science broken down into very narrow specialties a scientific expert in one specialty does not make that person an automatic authority in all things science.
In this way the logic of the 30,000 petition is completely flawed, which isn't surprising given its questionable beginnings.
