Environmental models as "useless arithmetic"

Here's another book I'd like to read: Useless arithmetic: Why environmental scientists can't predict the future. Great title*.

The authors sound like a cool pair:
Noted coastal geologist Orrin Pilkey and environmental scientist Linda Pilkey-Jarvis show that the quantitative mathematical models policy makers and government administrators use to form environmental policies are seriously flawed. Based on unrealistic and sometimes false assumptions, these models often yield answers that support unwise policies. . . .

The authors demonstrate how many modelers have been reckless, employing fudge factors to assure "correct" answers and caring little if their models actually worked.
I stumbled on the book after reading of Pilkey in a John Stossel piece on federally-subsidized flood insurance. Stossel says Pilkey "has been one of the most persistent critics of the government's [flood insurance] policies."


*It sounds like one of Gary Jones's headlines at Muck & Mystery
