Climatologist Dr. Roy Spencer: "Sec. Perry goes against the supposed consensus of scientists, it was not outlandish, it wasn’t a denial of a known fact. It was a valid opinion on an uncertain area of science. AMS, me thinks thou doth protest too much...The truth is, no one knows just how much of recent warming was human-caused, including those thousands of 'independent' scientists. They pin the blame on CO2 partly because that’s all they can think of, and we still don’t understand natural sources of climate change."
"Why did AMS stick up for 'consensus': 'All of the scientific institutions are going to jump on the bandwagon, with politically savvy committees agreeing with each other; they are in effect being paid by the government to agree with the consensus through billions of dollars in grants and contracts. If there is no global warming crisis, there would be little congressional funding to study it, and thousands of climate-dependent careers (including mine) simply wouldn’t exist. That money also trickles down to the AMS, which is paid to hold scientific conferences, workshops, and publish the resulting research studies in scientific journals. They have a vested interest in the gravy train continuing."
Meteorologist Anthony Watts: 'For the AMS to admonish Perry that there’s no room for debate on Carbon Dioxide as being the primary driver, is essentially to deny the process of science itself. Science is often right, and also often wrong, but just as often, it is self-correcting. If global warming hadn’t become such an entangled and messy social and political issue, it’s likely that science would have done some levels of self-correction on the issue already.'
Asked whether CO2 emissions are primarily responsible for climate change, Perry told CNBC's "Squawk Box": "No, most likely the primary control knob is the ocean waters and this environment that we live in." "The fact is this shouldn't be a debate about, 'Is the climate changing, is man having an effect on it?' Yeah, we are. The question should be just how much, and what are the policy changes that we need to make to effect that?" he said.
