"I guess it shouldn't have surprised me these gentlemen -- 49 out of tens of thousands of former NASA employees (more than 18,000 people currently work for NASA, so this is about 0.27% of current employees) would next move into the emotional language. It shouldn't have surprised me, but it disappointed me just the same."
"Here's the note I received from Russell Schweickart after I alerted him about the letter (he was unaware of it): To my knowledge most of the signatories on this letter are in fact engineers (or former engineers). Some are (or were) scientists... But none, to my limited knowledge, are what I would consider qualified climatologists. AND... they have every right to state and argue for their opinion, and I fully support their right on that score."
"Based on the job titles listed in the letter signatures, by my count they include 23 administrators, 8 astronauts, 7 engineers, 5 technicians, and 4 scientists/mathematicians of one sort or another (none of those sorts having the slightest relation to climate science). Amongst the signatories and their 1,000 years of combined professional experience, that appears to include a grand total of zero hours of climate research experience, and zero peer-reviewed climate science papers."
