EXPERTS disAGREE: In 1997, Dr. Frederick Seitz, past president of the National Academy of Sciences, invited colleagues to sign a petition based on Robinson's work, which received more than 20,000 signers, most of whom hold advanced degrees in relevant fields of study. That petition stated, in part:

"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."
