Is NASA playing fast and loose with climate change science? That's the contention of a group of 49 former NASA scientists and astronauts.
On March 28 the group sent a letter to NASA administrator Charles Bolden, Jr., blasting the agency for making unwarranted claims about the role of carbon dioxide in global warming, Business Insider reported.
"We believe the claims by NASA and GISS [NASA Goddard Institute for Space Studies], 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."
The group features some..
marquee names, including Michael F. Collins, Walter Cunningham and five other Apollo astronauts, as well as two former directors of NASA's Johnson Space Center in Houston.
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."
