-
- This book, and the model on which it is based, was recently discussed in
- this group.
-
- Those who supported the book (myself included) see its models as a first
- order approximation with value for analysis on a global scale.
-
- An earlier book by some of the same authors used a
- similar model and its predictions over the 20 year period between the
- books were fairly good (according to the authors), but how much credibility
- this lends to extrapolations 100 years ahead is an open question.
-
- Those who didn't like the models complained that it did not represent
- non-linearities and demand saturation in the real world. Some feel
- that long-term modeling (more than a century ahead) is a waste of
- time since conditions will change so much in the
- intervening period.
-
- Most people discussing the model were not familiar with the specific
- mathematics, although the book gives a ref for a technical report
- that does provide these details.
-
- The authors challenge critics to present something better which some
- of them aren't inclined to do since they disagree with the whole
- field.
-
- In short, the field of science used in creating this model is new
- there is no solid consensus on it yet.
