So says Al Gore on global warming. What did he mean? His defenders say that he was simply suggesting that now is the time to talk about the problem and not the solution. This is supported, although not entirely, about the question he was asked ("do we scare them or give them hope") and his next statement that says we are in something called "Category 5 denial" and that we can discuss solutions later.
On the other hand, it seems just as plausible to read his statement as an endorsement of useful exaggeration, of providing information that is "inaccurate, but true."
His movie seems to be an example of the latter..
