Roger Simon runs into a Hollywood nitwit who believes in global warming because NASA says so.
Point 1: “NASA” doesn’t say so. One duplicitous ideologue masquerading as a climate scientist at one particular NASA center says so. That center had to confess error on his behalf (no doubt through clenched teeth).
Point 2: “NASA” has no opinion on anything. NASA is a government agency, with thousands of employees, of varying opinions. The previous NASA administrator, in fact, famously outraged the warm mongers with his own skepticism, but if any one person could have spoken for NASA at the time, it would have been Mike Griffin, not James Hansen.
Point 3: NASA has had many spectacular achievements in the past. It has also had many spectacular failures. To rely on it, as an agency, as a source of authority for something (particularly when there is no official agency position on it) is foolish. In fact, this false sense that people have in NASA as an authority has contributed greatly to the difficulty over the past decades to raise money for private ventures. This is because investors, when doing due diligence on an investment decisions, have often gone to someone at NASA who knows nothing about the venture, and relied on their foolish advice, for no other reason than they worked for NASA.
Anyway, this gets back to the foolishness of relying on people who claim to be scientists, instead of on science itself.
