Al Gore has appeared before Congress and more importantly (judging by popularity ratings) Oprah Winfrey saying that man-made Global Warming is now "settled science", comparing dissenters to "Flat-Earthers". Some Global Warming activists have gone farther than that- Scott Pelley has been quoted on the CBS News PublicEye blog saying: "There is virtually no disagreement in the scientific community any longer about ‘global warming.’ … The science that has been done in the last three to five years has been conclusive.” Pelley also posted this quote to the same blog: “If I do an interview with [Holocaust survivor] Elie Wiesel, am I required as a journalist to find a Holocaust denier?”
Is that the case? Are those who deny that the Global Warming that occurred between 1970 and 2000 (there has been no change the last eight years) no better than holocaust deniers? Let's look at them. There are a few deniers associated with the Oregon Institute of Science and Medicine ... 31,000 of them! "On May 19th 2008, OISM announced that over 31,000 scientists, including more than 9,000 with Ph.D.s, signed a petition that states, "... There is no convincing scientific evidence that human release of carbon dioxide, methane or other greenhouse gases is causing, or will cause in the future, catastrophic heating of the Earth's atmosphere and disruption of the Earth's climate..." Signatories include such luminaries as theoretical physicist Freeman Dyson, MIT's atmospheric physicist Richard Lindzen and first National Academy of Sciences president Frederick Seitz. More than 40 signatories are members of the prestigious national Academy of Sciences."
Then there's the American Physical Society , which has reversed its stance on climate change and is now proclaiming that many of its members disbelieve in human-induced global warming. "In a posting to the APS forum, editor Jeffrey Marque explains,"There is a considerable presence within the scientific community of people who do not agree with the IPCC conclusion that anthropogenic CO2 emissions are very probably likely to be primarily responsible for global warming that has occurred since the Industrial Revolution." This Article shows one of the things they are discussing:
"WASHINGTON (7-15-08) - Mathematical proof that there is no “climate crisis” appears today in a major, peer-reviewed paper in Physics and Society, a learned journal of the 10,000-strong American Physical Society, SPPI reports. Christopher Monckton, who once advised Margaret Thatcher, demonstrates via 30 equations that computer models used by the UN’s climate panel (IPCC) were pre-programmed with overstated values for the three variables whose product is “climate sensitivity” (temperature increase in response to greenhouse-gas increase), resulting in a 500-2000% overstatement of CO2’s effect on temperature in the IPCC’s latest climate assessment report, published in 2007."
Let's not leave Europe out- in a paper from the Danish National Space Center entitled "Reply to Lockwood and Fröhlich –
The persistent role of the Sun in climate forcing", they authors say, "As for the upward linear trend removed from Fig. 2 (lower), it is customary to attribute to greenhouse gases any increase in global temperatures not due to solar changes. While that is reasonable, one cannot distinguish between the effects of anthropogenic gases such as carbon dioxide and of natural greenhouse gases. For example, increased evaporation means that infrared radiation from water vapor, by far the most important greenhouse gas, will tend to provide positive feedback for any global warming, whether driven by anthropogenic or solar forcing. In any case, the most recent global temperature trend is close to zero."
It's starting to sound to me that there's some wiggle room here, that anthropogenic Global Warming is "settled science" only to Al Gore. What is the truth? I don't know; I'm not competent to say. Neither is Al Gore. In fact, neither are many of the scientists on both sides of the debate; a scientist, when speaking outside his specialty, is merely an educated layman. Even Nobel Prize winners. You doubt me? I offer in evidence William Shockley
, 1956 Noble Prize winner for physics, co-inventor of the transistor, one of the founders of silicon valley... who believed that it could be mathematically proven that Blacks are inferior to Whites. His math was correct, but his presumptions were wrong- which is what Global Warming debaters are saying about each other.
This being the case, it bothers me that both Presidential candidates are big believers, and want us to spend a fortune on programs that will further damage our economy before it is even determined what can be done, and what should be. I'm hoping that the new Congress will consider any such measures closely.
