Deroy Murdock‘s latest column focuses on an interesting twist in the global warming debate:

To the long list of right-wing, knuckle-dragging know-nothings who dare question so-called “global warming,” environmentalists now can add six Apollo astronauts, two rocket men who flew aboard Skylab, and a pair of former directors of the Johnson Space Center (JSC).

These veterans of America’s space program are among the 49 retired NASA employees who recently asked the agency to halt what they consider its unscientific advocacy of climate alarmism.

In a letter to NASA administrator Charles Bolden Jr., these rocket scientists, space explorers, and other men and women of reason requested that “NASA and the Goddard Institute for Space Studies (GISS) refrain from including unproven remarks in public releases and websites.” They added: “We believe the claims by NASA and GISS, 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. 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.”
