Doesn’t make you an expert on climate science. That seems to be the case with a letter written to NASA recently by a group that includes some ex-astronauts. It’s gotten some notice in the press recently, because apparently some people think that just because you’re an astronaut, you now know everything. Well, they’re wrong, as Phil Plait points out in the Bad Astronomy blog.
I’ve been getting lots of email and other notes about a group of 49 people — including some ex-astronauts — who have written a public letter to NASA complaining about the space agency’s stance that global warming exists and is caused by humans.
You can guess how I feel about it. But to be clear: it’s more denialist spin, nonsense, and noise. You can read the original leter here, and then I strongly suggest reading Shawn Otto’s devastating deconstruction of it. You can also read the response to this letter by NASA’s Chief Scientist Waleed Abdalatim if you’d like.
I’ll note that it doesn’t matter that former astronauts signed this propaganda letter — I’ve written about Apollo 17′s Harrison Schmitt and his climate change denialism before — but I note it does matter that of the 49 signatories on that letter, not one is an actual working climate scientist. That should give you pause. I’ll also note that 49 former NASA employees is a tiny, tiny fraction of the total. It’s not hard to find statistical outliers in a group that big. I knew a creationistwho worked for NASA!
