At our Process Safety Report site we published the post All models are wrong, but some are useful. It turned out that, only one day earlier, my colleague Ugo Bardi also published a substack post: Are we on the Edge of Collapse? Impressive Data from a Recalibration of World3.

Both posts provide interesting and useful insights as to the use of models when it comes to understanding complex systems such as climate change and resource depletion.

The post The Value of Models: How to Use Models Without Believing in Them summarizes the two approaches (mine and Bardi’s). It also considers the role of Large Language Models (LLMs) within this overall discussion.
