NASA Administrator, Michael Griffin, is backing away from comments he made last week  in a National Public Radio interview. At the time Griffin stated that, " ...a trend of global warming exists, I am not sure that it is fair to say that it is a problem we must wrestle with.”
Today the White House appointed Griffin is apologizing to NASA staff  saying that,
All I can really do is apologize to all you guys ... I feel badly that I caused this amount of controversy over something like this."
The White House appointed administrator caused a flurry of controversy over his remarks prompting longtime NASA scientist, Jim Hansen to remark  that "it indicates a complete ignorance of understanding the implications of climate change."
