The way the model results are reported needs to change. The worst case results were presented to the public as the expected outcome. This is something between highly deceptive and unethical. (think yelling "Fire!" in a crowded movie theater.) The best, worst and average outcomes from the model need to be reported. Perhaps even two sets of best, worst and average outcomes. One with large scale intervention and one with zero intervention.
A very simple way to think about when you know the model has failed: The model has failed when it makes 100 predictions with 95% certainty and more than 5 of the actual outcomes are outside the bounds defined by the best and worst outcomes. Note: I said SIMPLE.
The modelers need to be careful about what they say. Next time they predict armageddon, no one will take them seriously.
