The concern I have with AGW is the potential for the loss of prestige by
science. If the climate doesn't warm over the next 20 years, in the minds of
the public it will be disproven, and the public will perceive it was at
least evidence that scientists are often wrong,

At the current time most climate scientists think the theory of AGW is
true but don't claim to be 100% certain.

To find out for sure we may have to wait 20 years.

In the meantime its safer to prepare for the possibility that its
true.
