Global Warming Zealots Get
Slammed by NASA Scientists
|by Mitch Battros - Earth Changes Media|
49 former NASA scientists and astronauts sent a letter to NASA Administrator Charles Bolden last week admonishing the agency for its role in advocating a high degree of certainty that man-made CO2 is a major cause of climate change while neglecting empirical evidence that calls the theory into question.
The group, which includes seven Apollo astronauts and two former directors of NASA's Johnson Space Center in Houston, are dismayed over the failure of NASA, and specifically the Goddard Institute For Space Studies (GISS), to make an objective assessment of all available scientific data on climate change. They charge that NASA is relying too heavily on complex climate models that have proven scientifically inadequate in predicting climate only one or two decades in advance.
"We believe the claims by NASA and Goddard, that man-made carbon dioxide is having a catastrophic impact on global climate change are not substantiated, especially when considering thousands of years of empirical data," the group wrote. "With hundreds of well-known climate scientists and tens of thousands of other scientists publicly declaring their disbelief in the catastrophic forecasts, coming particularly from the GISS leadership, it is clear that the science is NOT settled."
H. Leighton Steward, chairman of the non-profit Plants Need CO2, noted that many of the former NASA scientists harbored doubts about the significance of the C02-climate change theory and have concerns over NASA's advocacy on the issue. While making presentations in late 2011 to many of the signatories of the letter, Steward realized that the NASA scientists should make their concerns known to NASA and the GISS.
"These American heroes - the astronauts that took to space and the scientists and engineers that put them there - are simply stating their concern over NASA's extreme advocacy for an unproven theory," said Leighton Steward. "There's a concern that if it turns out that CO2 is not a major cause of climate change, NASA will have put the reputation of NASA, NASA's current and former employees, [and put] the very reputation of science itself at risk of public ridicule and distrust."
The letter included a request for NASA to refrain from mentioning CO2 as a cause of global warming in future press releases and websites. The agency's "Global Climate Change" webpage says that "Humans have increased atmospheric CO2 concentration by a third since the Industrial Revolution began. This is the most important long-lived "forcing" of climate change."
The EPA website says that "Increasing levels of greenhouse gases like carbon dioxide in the atmosphere since pre-industrial times are well-documented and understood." It goes on to say that "The atmospheric buildup of CO2 and other greenhouse gases is largely the result of human activities such as the burning of fossil fuels."
What does NASA say?
"NASA sponsors research into many areas of cutting-edge scientific inquiry, including the relationship between carbon dioxide and climate," says the agency's chief scientist, Dr. Waleed Abdalati. "As an agency, NASA does not draw conclusions and issue 'claims' about research findings. We support open scientific inquiry and discussion...If the authors of this letter disagree with specific scientific conclusions made public by NASA scientists, we encourage them to join the debate in the scientific literature or public forums rather than restrict any discourse."
