'This is the last chance'

"Exactly 20 years after warning America about global warming, a top NASA scientist said the situation has gotten so bad that the world's only hope is drastic action."
"We're toast if we don't get on a very different path," Hansen, director of the Goddard Institute of Space Sciences who is sometimes called the godfather of global warming science, told The Associated Press. "This is the last chance." (ap)

Haven't these so-called "scientists" been screaming the sky is falling, and that this is our "last chance," for a long time? I bet he said the same thing in 1988 that he said earlier this week. Why should we believe you now Mr. Hansen? Your attempts at scaring us aren't working.

(wow, you know I think that was the second chicken little reference we've made in the last few weeks. odd)
