The BBC have now responded to my request to see the email exchange which Roger Harrabin claims took place between himself and the World Meteorological Organisation at the time of the Jo Abbess "change the report or else" story.
It will probably come as no surprise to anyone that the Beeb is refusing to release the emails.
At the end of the day then, we have the word of one man, Roger Harrabin that the email exchange took place and what its contents were.
If he were a blogger, we would not accept this lack of any evidence. If you don't present evidence, the blogosphere isn't going to take your word for it.
This same principle applies to the BBC too. But more so.
