Q: But back in the 1970s, scientists told us the world was cooling! Why should we believe them about global warming now?
A: Don’t confuse a Newsweek cover story with a scientific consensus. Just because journalists latch on to one research paper and drum up a media storm about it doesn’t mean that the scientific community at large views that research paper as either definitive or compelling.
Q: Isn’t it unethical for scientists to delete raw data? How can we trust people who do that?
A: There is nothing unethical about deleting your copy of someone else’s raw data once you have finished using it, especially if that is a condition of access to that raw data. You can always get another copy of that raw data from the people who generated it if you need to look at it again.
People who keep harassing someone for a deleted copy of someone else’s raw data instead of going to the originator of that raw data for a copy of their own? Even when it’s been explained to them over and over that the originator is the only person who can provide another copy of that raw data? Now that’s unethical.
