They seem to talk about the change, but never any time tables. I mean, is the next ice age in 50 years? 150? Is it to late to do anything (as if everyone would do anything) and isn't the earth supposed to go through these climate shifts?
Easy, we don't fully know when the next ice age will come. Then again most AGW supporters either use information that stretches millions of years or only goes back to the 1800's.
