Plants Need CO2 To GrowApril 10, 2012
Former NASA Scientists and Astronauts Blast Agency for Disregarding Climate Change Evidence
Washington, D.C.-Nearly 50 former NASA scientists and astronauts-including seven Apollo astronauts and two former directors of NASA's Johnson Space Center in Houston-are condemning NASA for the space agency's role in advocating that man-made carbon dioxide (CO2) is a major cause of climate change while ignoring compelling empirical evidence that calls the theory into question.
In a formal letter sent to NASA Administrator Charles Bolden, the group criticizes NASA, and specifically the Goddard Institute for Space Studies (GISS), for its failure to make an objective assessment of all available scientific data on climate change. The scientists and astronauts argue that NASA is relying too heavily on complex climate models that have proven scientifically deficient in predicting climate change.
"These American heroes-the astronauts that took to space and the scientists and engineers that put them there-are right to criticize NASA's advocacy of an extreme and unsubstantiated position," said Leighton Steward, chairman of Plants Need CO2. Leighton Steward, a scientist, environmentalist, and New York Times best-selling author, had made presentations to many of the signatories of the letter and encouraged several in the group to come forward to make their concerns known to NASA.
"It's beyond disturbing that NASA would endanger its reputation and risk misleading the public by engaging in aggressive advocacy of scientifically unverified positions," said Leighton Steward. "NASA has a duty to make an objective assessment of all the available scientific data on climate change-including empirical evidence that calls the theory of man-made global warming into question."
The formal letter reads in part:
