Sorry, but this is really unimpressive. "was told" means "was asked an unspecified question about, by a journalist". I'm guessing that Pachauri gets a lot of questions from journalists that, for one reason or another, don't merit close investigation.
Mr Bagla said he had informed Dr Pachauri that Graham Cogley, a professor at Ontario Trent University and a leading glaciologist, had dismissed the 2035 date as being wrong by at least 300 years. Professor Cogley believed the IPCC had misread the date in a 1996 report which said the glaciers could melt significantly by 2350.
I am currently on -2 for the original mistaken remark and +5 for this one, which means I've garnered one more upvote than downvote for screwing up and then admitting it.
I think that's wrong. Could someone please downvote one of these exactly once? (To be more precise: if you're reading this and the total score of its parent and great-grandparent is more than 2, please downvote one of them.)
